How to Install the GNU C Library
|
||||
================================
|
||||
|
||||
Installation of the GNU C library is relatively simple.
|
||||
|
||||
You need the latest version of GNU `make'. Modifying the GNU C
|
||||
Library to work with other `make' programs would be so hard that we
|
||||
recommend you port GNU `make' instead. *Really.*
|
||||
|
||||
To configure the GNU C library for your system, run the shell script
|
||||
`configure' with `sh'. Use an argument which is the conventional GNU
|
||||
name for your system configuration--for example, `sparc-sun-sunos4.1',
|
||||
for a Sun 4 running Sunos 4.1. *Note Installation:
|
||||
(gcc.info)Installation, for a full description of standard GNU
|
||||
configuration names. If you omit the configuration name, `configure'
|
||||
will try to guess one for you by inspecting the system it is running
|
||||
on. It may or may not be able to come up with a guess, and the its
|
||||
guess might be wrong. `configure' will tell you the canonical name of
|
||||
the chosen configuration before proceeding.
|
||||
|
||||
The GNU C Library currently supports configurations that match the
|
||||
following patterns:

||||

While no other configurations are supported, there are handy aliases
|
||||
for these few. (These aliases work in other GNU software as well.)

Here are some options that you should specify (if appropriate) when
|
||||
you run `configure':
|
||||
|
||||
`--with-gnu-ld'
|
||||
Use this option if you plan to use GNU `ld' to link programs with
|
||||
the GNU C Library. (We strongly recommend that you do.) This
|
||||
option enables use of features that exist only in GNU `ld'; so if
|
||||
you configure for GNU `ld' you must use GNU `ld' *every time* you
|
||||
link with the GNU C Library, and when building it.
|
||||
|
||||
`--with-gnu-as'
|
||||
Use this option if you plan to use the GNU assembler, `gas', when
|
||||
building the GNU C Library. On some systems, the library may not
|
||||
build properly if you do *not* use `gas'.
|
||||
|
||||
`--nfp'
|
||||
Use this option if your computer lacks hardware floating point
|
||||
support.
|
||||
|
||||
`--prefix=DIRECTORY'
|
||||
Install machine-independent data files in subdirectories of
|
||||
`DIRECTORY'. (You can also set this in `configparms'; see below.)
|
||||
|
||||
`--exec-prefix=DIRECTORY'
|
||||
Install the library and other machine-dependent files in
|
||||
subdirectories of `DIRECTORY'. (You can also set this in
|
||||
`configparms'; see below.)
|
||||
|
||||
The simplest way to run `configure' is to do it in the directory
|
||||
that contains the library sources. This prepares to build the library
|
||||
in that very directory.
|
||||
|
||||
You can prepare to build the library in some other directory by going
|
||||
to that other directory to run `configure'. In order to run configure,
|
||||
you will have to specify a directory for it, like this:
|
||||
|
||||
mkdir sun4
|
||||
cd sun4
|
||||
../configure sparc-sun-sunos4.1
|
||||
|
||||
`configure' looks for the sources in whatever directory you specified
|
||||
for finding `configure' itself. It does not matter where in the file
|
||||
system the source and build directories are--as long as you specify the
|
||||
source directory when you run `configure', you will get the proper
|
||||
results.
|
||||
|
||||
This feature lets you keep sources and binaries in different
|
||||
directories, and that makes it easy to build the library for several
|
||||
different machines from the same set of sources. Simply create a build
|
||||
directory for each target machine, and run `configure' in that
|
||||
directory specifying the target machine's configuration name.
|
||||
|
||||
The library has a number of special-purpose configuration parameters.
|
||||
These are defined in the file `Makeconfig'; see the comments in that
|
||||
file for the details.
|
||||
|
||||
But don't edit the file `Makeconfig' yourself--instead, create a
|
||||
file `configparms' in the directory where you are building the library,
|
||||
and define in that file the parameters you want to specify.
|
||||
`configparms' should *not* be an edited copy of `Makeconfig'; specify
|
||||
only the parameters that you want to override. To see how to set these
|
||||
parameters, find the section of `Makeconfig' that says "These are the
|
||||
configuration variables." Then for each parameter that you want to
|
||||
change, copy the definition from `Makeconfig' to your new `configparms'
|
||||
file, and change the value as appropriate for your system.
|
||||
|
||||
It is easy to configure the GNU C library for cross-compilation by
|
||||
setting a few variables in `configparms'. Set `CC' to the
|
||||
cross-compiler for the target you configured the library for; it is
|
||||
important to use this same `CC' value when running `configure', like
|
||||
this: `CC=TARGET-gcc configure TARGET'. Set `BUILD_CC' to the compiler
|
||||
to use for for programs run on the build system as part of compiling
|
||||
the library. You may need to set `AR' and `RANLIB' to cross-compiling
|
||||
versions of `ar' and `ranlib' if the native tools are not configured to
|
||||
work with object files for the target you configured for.
|
||||
|
||||
Some of the machine-dependent code for some machines uses extensions
|
||||
in the GNU C compiler, so you may need to compile the library with GCC.
|
||||
(In fact, all of the existing complete ports require GCC.)
|
||||
|
||||
The current release of the C library contains some header files that
|
||||
the compiler normally provides: `stddef.h', `stdarg.h', and several
|
||||
files with names of the form `va-MACHINE.h'. The versions of these
|
||||
files that came with older releases of GCC do not work properly with
|
||||
the GNU C library. The `stddef.h' file in release 2.2 and later of GCC
|
||||
is correct. If you have release 2.2 or later of GCC, use its version
|
||||
of `stddef.h' instead of the C library's. To do this, put the line
|
||||
`override stddef.h =' in `configparms'. The other files are corrected
|
||||
in release 2.3 and later of GCC. `configure' will automatically detect
|
||||
whether the installed `stdarg.h' and `va-MACHINE.h' files are
|
||||
compatible with the C library, and use its own if not.
|
||||
|
||||
There is a potential problem with the `size_t' type and versions of
|
||||
GCC prior to release 2.4. ANSI C requires that `size_t' always be an
|
||||
unsigned type. For compatibility with existing systems' header files,
|
||||
GCC defines `size_t' in `stddef.h' to be whatever type the system's
|
||||
`sys/types.h' defines it to be. Most Unix systems that define `size_t'
|
||||
in `sys/types.h', define it to be a signed type. Some code in the
|
||||
library depends on `size_t' being an unsigned type, and will not work
|
||||
correctly if it is signed.
|
||||
|
||||
The GNU C library code which expects `size_t' to be unsigned is
|
||||
correct. The definition of `size_t' as a signed type is incorrect.
|
||||
Versions 2.4 and later of GCC always define `size_t' as an unsigned
|
||||
type, and GCC's `fixincludes' script massages the system's
|
||||
`sys/types.h' so as not to conflict with this.
|
||||
|
||||
In the meantime, we work around this problem by telling GCC
|
||||
explicitly to use an unsigned type for `size_t' when compiling the GNU C
|
||||
library. `configure' will automatically detect what type GCC uses for
|
||||
`size_t' arrange to override it if necessary.
|
||||
|
||||
To build the library, type `make lib'. This will produce a lot of
|
||||
output, some of which looks like errors from `make' (but isn't). Look
|
||||
for error messages from `make' containing `***'. Those indicate that
|
||||
something is really wrong.
|
||||
|
||||
To build and run some test programs which exercise some of the
|
||||
library facilities, type `make tests'. This will produce several files
|
||||
with names like `PROGRAM.out'.
|
||||
|
||||
To format the `GNU C Library Reference Manual' for printing, type
|
||||
`make dvi'. To format the Info version of the manual for on line
|
||||
reading with `C-h i' in Emacs or with the `info' program, type
|
||||
`make info'.
|
||||
|
||||
To install the library and its header files, and the Info files of
|
||||
the manual, type `make install', after setting the installation
|
||||
directories in `configparms'. This will build things if necessary,
|
||||
before installing them.
|
||||
|
||||
Reporting Bugs
|
||||
==============
|
||||
|
||||
There are probably bugs in the GNU C library. There are certainly
|
||||
errors and omissions in this manual. If you report them, they will get
|
||||
fixed. If you don't, no one will ever know about them and they will
|
||||
remain unfixed for all eternity, if not longer.
|
||||
|
||||
To report a bug, first you must find it. Hopefully, this will be the
|
||||
hard part. Once you've found a bug, make sure it's really a bug. A
|
||||
good way to do this is to see if the GNU C library behaves the same way
|
||||
some other C library does. If so, probably you are wrong and the
|
||||
libraries are right (but not necessarily). If not, one of the libraries
|
||||
is probably wrong.
|
||||
|
||||
Once you're sure you've found a bug, try to narrow it down to the
|
||||
smallest test case that reproduces the problem. In the case of a C
|
||||
library, you really only need to narrow it down to one library function
|
||||
call, if possible. This should not be too difficult.
|
||||
|
||||
The final step when you have a simple test case is to report the bug.
|
||||
When reporting a bug, send your test case, the results you got, the
|
||||
results you expected, what you think the problem might be (if you've
|
||||
thought of anything), your system type, and the version of the GNU C
|
||||
library which you are using. Also include the files `config.status'
|
||||
and `config.make' which are created by running `configure'; they will
|
||||
be in whatever directory was current when you ran `configure'.
|
||||
|
||||
If you think you have found some way in which the GNU C library does
|
||||
not conform to the ANSI and POSIX standards (*note Standards and
|
||||
Portability::.), that is definitely a bug. Report it!
|
||||
|
||||
Send bug reports to the Internet address `bug-glibc@prep.ai.mit.edu'
|
||||
or the UUCP path `mit-eddie!prep.ai.mit.edu!bug-glibc'. If you have
|
||||
other problems with installation or use, please report those as well.
|
||||
|
||||
If you are not sure how a function should behave, and this manual
|
||||
doesn't tell you, that's a bug in the manual. Report that too! If the
|
||||
function's behavior disagrees with the manual, then either the library
|
||||
or the manual has a bug, so report the disagreement. If you find any
|
||||
errors or omissions in this manual, please report them to the Internet
|
||||
address `bug-glibc-manual@prep.ai.mit.edu' or the UUCP path
|
||||
`mit-eddie!prep.ai.mit.edu!bug-glibc-manual'.
|
||||
|
||||
Adding New Functions
|
||||
====================
|
||||
|
||||
The process of building the library is driven by the makefiles, which
|
||||
make heavy use of special features of GNU `make'. The makefiles are
|
||||
very complex, and you probably don't want to try to understand them.
|
||||
But what they do is fairly straightforward, and only requires that you
|
||||
define a few variables in the right places.
|
||||
|
||||
The library sources are divided into subdirectories, grouped by
|
||||
topic. The `string' subdirectory has all the string-manipulation
|
||||
functions, `stdio' has all the standard I/O functions, etc.
|
||||
|
||||
Each subdirectory contains a simple makefile, called `Makefile',
|
||||
which defines a few `make' variables and then includes the global
|
||||
makefile `Rules' with a line like:
|
||||
|
||||
include ../Rules
|
||||
|
||||
The basic variables that a subdirectory makefile defines are:
|
||||
|
||||
`subdir'
|
||||
The name of the subdirectory, for example `stdio'. This variable
|
||||
*must* be defined.
|
||||
|
||||
`headers'
|
||||
The names of the header files in this section of the library, such
|
||||
as `stdio.h'.
|
||||
|
||||
`routines'
|
||||
`aux'
|
||||
The names of the modules (source files) in this section of the
|
||||
library. These should be simple names, such as `strlen' (rather
|
||||
than complete file names, such as `strlen.c'). Use `routines' for
|
||||
modules that define functions in the library, and `aux' for
|
||||
auxiliary modules containing things like data definitions. But the
|
||||
values of `routines' and `aux' are just concatenated, so there
|
||||
really is no practical difference.
|
||||
|
||||
`tests'
|
||||
The names of test programs for this section of the library. These
|
||||
should be simple names, such as `tester' (rather than complete file
|
||||
names, such as `tester.c'). `make tests' will build and run all
|
||||
the test programs. If a test program needs input, put the test
|
||||
data in a file called `TEST-PROGRAM.input'; it will be given to
|
||||
the test program on its standard input. If a test program wants
|
||||
to be run with arguments, put the arguments (all on a single line)
|
||||
in a file called `TEST-PROGRAM.args'.
|
||||
|
||||
`others'
|
||||
The names of "other" programs associated with this section of the
|
||||
library. These are programs which are not tests per se, but are
|
||||
other small programs included with the library. They are built by
|
||||
`make others'.
|
||||
|
||||
`install-lib'
|
||||
`install-data'
|
||||
`install'
|
||||
Files to be installed by `make install'. Files listed in
|
||||
`install-lib' are installed in the directory specified by `libdir'
|
||||
in `configparms' or `Makeconfig' (*note Installation::.). Files
|
||||
listed in `install-data' are installed in the directory specified
|
||||
by `datadir' in `configparms' or `Makeconfig'. Files listed in
|
||||
`install' are installed in the directory specified by `bindir' in
|
||||
`configparms' or `Makeconfig'.
|
||||
|
||||
`distribute'
|
||||
Other files from this subdirectory which should be put into a
|
||||
distribution tar file. You need not list here the makefile itself
|
||||
or the source and header files listed in the other standard
|
||||
variables. Only define `distribute' if there are files used in an
|
||||
unusual way that should go into the distribution.
|
||||
|
||||
`generated'
|
||||
Files which are generated by `Makefile' in this subdirectory.
|
||||
These files will be removed by `make clean', and they will never
|
||||
go into a distribution.
|
||||
|
||||
`extra-objs'
|
||||
Extra object files which are built by `Makefile' in this
|
||||
subdirectory. This should be a list of file names like `foo.o';
|
||||
the files will actually be found in whatever directory object
|
||||
files are being built in. These files will be removed by
|
||||
`make clean'. This variable is used for secondary object files
|
||||
needed to build `others' or `tests'.
|
||||
|
||||
Porting the GNU C Library
|
||||
=========================
|
||||
|
||||
The GNU C library is written to be easily portable to a variety of
|
||||
machines and operating systems. Machine- and operating system-dependent
|
||||
functions are well separated to make it easy to add implementations for
|
||||
new machines or operating systems. This section describes the layout of
|
||||
the library source tree and explains the mechanisms used to select
|
||||
machine-dependent code to use.
|
||||
|
||||
All the machine-dependent and operating system-dependent files in the
|
||||
library are in the subdirectory `sysdeps' under the top-level library
|
||||
source directory. This directory contains a hierarchy of
|
||||
subdirectories (*note Hierarchy Conventions::.).
|
||||
|
||||
Each subdirectory of `sysdeps' contains source files for a
|
||||
particular machine or operating system, or for a class of machine or
|
||||
operating system (for example, systems by a particular vendor, or all
|
||||
machines that use IEEE 754 floating-point format). A configuration
|
||||
specifies an ordered list of these subdirectories. Each subdirectory
|
||||
implicitly appends its parent directory to the list. For example,
|
||||
specifying the list `unix/bsd/vax' is equivalent to specifying the list
|
||||
`unix/bsd/vax unix/bsd unix'. A subdirectory can also specify that it
|
||||
implies other subdirectories which are not directly above it in the
|
||||
directory hierarchy. If the file `Implies' exists in a subdirectory,
|
||||
it lists other subdirectories of `sysdeps' which are appended to the
|
||||
list, appearing after the subdirectory containing the `Implies' file.
|
||||
Lines in an `Implies' file that begin with a `#' character are ignored
|
||||
as comments. For example, `unix/bsd/Implies' contains:
|
||||
# BSD has Internet-related things.
|
||||
unix/inet
|
||||
|
||||
and `unix/Implies' contains:
|
||||
posix
|
||||
|
||||
So the final list is `unix/bsd/vax unix/bsd unix/inet unix posix'.
|
||||
|
||||
`sysdeps' has two "special" subdirectories, called `generic' and
|
||||
`stub'. These two are always implicitly appended to the list of
|
||||
subdirectories (in that order), so you needn't put them in an `Implies'
|
||||
file, and you should not create any subdirectories under them.
|
||||
`generic' is for things that can be implemented in machine-independent
|
||||
C, using only other machine-independent functions in the C library.
|
||||
`stub' is for "stub" versions of functions which cannot be implemented
|
||||
on a particular machine or operating system. The stub functions always
|
||||
return an error, and set `errno' to `ENOSYS' (Function not
|
||||
implemented). *Note Error Reporting::.
|
||||
|
||||
A source file is known to be system-dependent by its having a
|
||||
version in `generic' or `stub'; every system-dependent function should
|
||||
have either a generic or stub implementation (there is no point in
|
||||
having both).
|
||||
|
||||
If you come across a file that is in one of the main source
|
||||
directories (`string', `stdio', etc.), and you want to write a machine-
|
||||
or operating system-dependent version of it, move the file into
|
||||
`sysdeps/generic' and write your new implementation in the appropriate
|
||||
system-specific subdirectory. Note that if a file is to be
|
||||
system-dependent, it *must not* appear in one of the main source
|
||||
directories.
|
||||
|
||||
There are a few special files that may exist in each subdirectory of
|
||||
`sysdeps':
|
||||
|
||||
`Makefile'
|
||||
A makefile for this machine or operating system, or class of
|
||||
machine or operating system. This file is included by the library
|
||||
makefile `Makerules', which is used by the top-level makefile and
|
||||
the subdirectory makefiles. It can change the variables set in the
|
||||
including makefile or add new rules. It can use GNU `make'
|
||||
conditional directives based on the variable `subdir' (see above)
|
||||
to select different sets of variables and rules for different
|
||||
sections of the library. It can also set the `make' variable
|
||||
`sysdep-routines', to specify extra modules to be included in the
|
||||
library. You should use `sysdep-routines' rather than adding
|
||||
modules to `routines' because the latter is used in determining
|
||||
what to distribute for each subdirectory of the main source tree.
|
||||
|
||||
Each makefile in a subdirectory in the ordered list of
|
||||
subdirectories to be searched is included in order. Since several
|
||||
system-dependent makefiles may be included, each should append to
|
||||
`sysdep-routines' rather than simply setting it:
|
||||
|
||||
sysdep-routines := $(sysdep-routines) foo bar
|
||||
|
||||
`Subdirs'
|
||||
This file contains the names of new whole subdirectories under the
|
||||
top-level library source tree that should be included for this
|
||||
system. These subdirectories are treated just like the
|
||||
system-independent subdirectories in the library source tree, such
|
||||
as `stdio' and `math'.
|
||||
|
||||
Use this when there are completely new sets of functions and header
|
||||
files that should go into the library for the system this
|
||||
subdirectory of `sysdeps' implements. For example,
|
||||
`sysdeps/unix/inet/Subdirs' contains `inet'; the `inet' directory
|
||||
contains various network-oriented operations which only make sense
|
||||
to put in the library on systems that support the Internet.
|
||||
|
||||
`Dist'
|
||||
This file contains the names of files (relative to the
|
||||
subdirectory of `sysdeps' in which it appears) which should be
|
||||
included in the distribution. List any new files used by rules in
|
||||
the `Makefile' in the same directory, or header files used by the
|
||||
source files in that directory. You don't need to list files that
|
||||
are implementations (either C or assembly source) of routines
|
||||
whose names are given in the machine-independent makefiles in the
|
||||
main source tree.
|
||||
|
||||
`configure'
|
||||
This file is a shell script fragment to be run at configuration
|
||||
time. The top-level `configure' script uses the shell `.' command
|
||||
to read the `configure' file in each system-dependent directory
|
||||
chosen, in order. The `configure' files are often generated from
|
||||
`configure.in' files using Autoconf.
|
||||
|
||||
A system-dependent `configure' script will usually add things to
|
||||
the shell variables `DEFS' and `config_vars'; see the top-level
|
||||
`configure' script for details. The script can check for
|
||||
`--with-PACKAGE' options that were passed to the top-level
|
||||
`configure'. For an option `--with-PACKAGE=VALUE' `configure'
|
||||
sets the shell variable `with_PACKAGE' (with any dashes in PACKAGE
|
||||
converted to underscores) to VALUE; if the option is just
|
||||
`--with-PACKAGE' (no argument), then it sets `with_PACKAGE' to
|
||||
`yes'.
|
||||
|
||||
`configure.in'
|
||||
This file is an Autoconf input fragment to be processed into the
|
||||
file `configure' in this subdirectory. *Note Introduction:
|
||||
(autoconf.info)Introduction, for a description of Autoconf. You
|
||||
should write either `configure' or `configure.in', but not both.
|
||||
The first line of `configure.in' should invoke the `m4' macro
|
||||
`GLIBC_PROVIDES'. This macro does several `AC_PROVIDE' calls for
|
||||
Autoconf macros which are used by the top-level `configure'
|
||||
script; without this, those macros might be invoked again
|
||||
unnecessarily by Autoconf.
|
||||
|
||||
That is the general system for how system-dependencies are isolated.
|
||||
|
||||
Layout of the `sysdeps' Directory Hierarchy
|
||||
-------------------------------------------
|
||||
|
||||
A GNU configuration name has three parts: the CPU type, the
|
||||
manufacturer's name, and the operating system. `configure' uses these
|
||||
to pick the list of system-dependent directories to look for. If the
|
||||
`--nfp' option is *not* passed to `configure', the directory
|
||||
`MACHINE/fpu' is also used. The operating system often has a "base
|
||||
operating system"; for example, if the operating system is `sunos4.1',
|
||||
the base operating system is `unix/bsd'. The algorithm used to pick
|
||||
the list of directories is simple: `configure' makes a list of the base
|
||||
operating system, manufacturer, CPU type, and operating system, in that
|
||||
order. It then concatenates all these together with slashes in
|
||||
between, to produce a directory name; for example, the configuration
|
||||
`sparc-sun-sunos4.1' results in `unix/bsd/sun/sparc/sunos4.1'.
|
||||
`configure' then tries removing each element of the list in turn, so
|
||||
`unix/bsd/sparc' and `sun/sparc' are also tried, among others. Since
|
||||
the precise version number of the operating system is often not
|
||||
important, and it would be very inconvenient, for example, to have
|
||||
identical `sunos4.1.1' and `sunos4.1.2' directories, `configure' tries
|
||||
successively less specific operating system names by removing trailing
|
||||
suffixes starting with a period.
|
||||
|
||||
As an example, here is the complete list of directories that would be
|
||||
tried for the configuration `sparc-sun-sunos4.1' (without the `--nfp'
|
||||
option):
|
||||
|
||||
sparc/fpu
|
||||
unix/bsd/sun/sunos4.1/sparc
|
||||
unix/bsd/sun/sunos4.1
|
||||
unix/bsd/sun/sunos4/sparc
|
||||
unix/bsd/sun/sunos4
|
||||

|
||||

|
||||

|
||||

|
||||
unix/bsd/sunos4.1/sparc
|
||||

|
||||

|
||||

|
||||

|
||||
unix/bsd/sunos
|
||||

|
||||

|
||||
unix/sun/sunos4.1/sparc
|
||||
unix/sun/sunos4.1
|
||||
unix/sun/sunos4/sparc
|
||||
unix/sun/sunos4
|
||||
unix/sun/sunos/sparc
|
||||
unix/sun/sunos
|
||||
unix/sun/sparc
|
||||
unix/sun
|
||||
unix/sunos4.1/sparc
|
||||

|
||||

|
||||

|
||||

|
||||

|
||||

||||

|
||||

||||

|
||||

|
||||

|
||||

|
||||
|
||||
Different machine architectures are conventionally subdirectories at
|
||||
the top level of the `sysdeps' directory tree. For example,
|
||||
`sysdeps/sparc' and `sysdeps/m68k'. These contain files specific to
|
||||
those machine architectures, but not specific to any particular
|
||||
operating system. There might be subdirectories for specializations of
|
||||
those architectures, such as `sysdeps/m68k/68020'. Code which is
|
||||
specific to the floating-point coprocessor used with a particular
|
||||
machine should go in `sysdeps/MACHINE/fpu'.
|
||||
|
||||
There are a few directories at the top level of the `sysdeps'
|
||||
hierarchy that are not for particular machine architectures.
|
||||
|
||||
`generic'
|
||||
`stub'
|
||||
As described above (*note Porting::.), these are the two
|
||||
subdirectories that every configuration implicitly uses after all
|
||||
others.
|
||||
|
||||
`ieee754'
|
||||
This directory is for code using the IEEE 754 floating-point
|
||||
format, where the C type `float' is IEEE 754 single-precision
|
||||
format, and `double' is IEEE 754 double-precision format. Usually
|
||||
this directory is referred to in the `Implies' file in a machine
|
||||
architecture-specific directory, such as `m68k/Implies'.
|
||||
|
||||
`posix'
|
||||
This directory contains implementations of things in the library in
|
||||
terms of POSIX.1 functions. This includes some of the POSIX.1
|
||||
functions themselves. Of course, POSIX.1 cannot be completely
|
||||
implemented in terms of itself, so a configuration using just
|
||||
`posix' cannot be complete.
|
||||
|
||||
`unix'
|
||||
This is the directory for Unix-like things. *Note Porting to
|
||||
Unix::. `unix' implies `posix'. There are some special-purpose
|
||||
subdirectories of `unix':
|
||||
|
||||
`unix/common'
|
||||
This directory is for things common to both BSD and System V
|
||||
release 4. Both `unix/bsd' and `unix/sysv/sysv4' imply
|
||||
`unix/common'.
|
||||
|
||||
`unix/inet'
|
||||
This directory is for `socket' and related functions on Unix
|
||||
systems. The `inet' top-level subdirectory is enabled by
|
||||
`unix/inet/Subdirs'. `unix/common' implies `unix/inet'.
|
||||
|
||||
`mach'
|
||||
This is the directory for things based on the Mach microkernel
|
||||
from CMU (including the GNU operating system). Other basic
|
||||
operating systems (VMS, for example) would have their own
|
||||
directories at the top level of the `sysdeps' hierarchy, parallel
|
||||
to `unix' and `mach'.
|
||||
|
||||
Porting the GNU C Library to Unix Systems
|
||||
-----------------------------------------
|
||||
|
||||
Most Unix systems are fundamentally very similar. There are
|
||||
variations between different machines, and variations in what
|
||||
facilities are provided by the kernel. But the interface to the
|
||||
operating system facilities is, for the most part, pretty uniform and
|
||||
simple.
|
||||
|
||||
The code for Unix systems is in the directory `unix', at the top
|
||||
level of the `sysdeps' hierarchy. This directory contains
|
||||
subdirectories (and subdirectory trees) for various Unix variants.
|
||||
|
||||
The functions which are system calls in most Unix systems are
|
||||
implemented in assembly code in files in `sysdeps/unix'. These files
|
||||
are named with a suffix of `.S'; for example, `__open.S'. Files ending
|
||||
in `.S' are run through the C preprocessor before being fed to the
|
||||
assembler.
|
||||
|
||||
These files all use a set of macros that should be defined in
|
||||
`sysdep.h'. The `sysdep.h' file in `sysdeps/unix' partially defines
|
||||
them; a `sysdep.h' file in another directory must finish defining them
|
||||
for the particular machine and operating system variant. See
|
||||
`sysdeps/unix/sysdep.h' and the machine-specific `sysdep.h'
|
||||
implementations to see what these macros are and what they should do.
|
||||
|
||||
The system-specific makefile for the `unix' directory (that is, the
|
||||
file `sysdeps/unix/Makefile') gives rules to generate several files
|
||||
from the Unix system you are building the library on (which is assumed
|
||||
to be the target system you are building the library *for*). All the
|
||||
generated files are put in the directory where the object files are
|
||||
kept; they should not affect the source tree itself. The files
|
||||
generated are `ioctls.h', `errnos.h', `sys/param.h', and `errlist.c'
|
||||
(for the `stdio' section of the library).
|
||||

||||
Contributors to the GNU C Library
|
||||
=================================
|
||||
|
||||
The GNU C library was written almost entirely by Roland McGrath, who
|
||||
now maintains it. Some parts of the library were contributed or worked
|
||||
on by other people.
|
||||
|
||||
* The `getopt' function and related code were written by Richard
|
||||
Stallman, David J. MacKenzie, and Roland McGrath.
|
||||
|
||||
* Most of the math functions are taken from 4.4 BSD; they have been
|
||||
modified only slightly to work with the GNU C library. The
|
||||
Internet-related code (most of the `inet' subdirectory) and several
|
||||
other miscellaneous functions and header files have been included
|
||||
with little or no modification.
|

* The random number generation functions `random', `srandom',
|
||||
`setstate' and `initstate', which are also the basis for the
|
||||
`rand' and `srand' functions, were written by Earl T. Cohen for

|
||||
|
||||
* The merge sort function `qsort' was written by Michael J. Haertel.
|

* The quick sort function used as a fallback by `qsort' was written
|

by Douglas C. Schmidt.
|

* The memory allocation functions `malloc', `realloc' and `free' and
|

GNU C Library NEWS -- history of user-visible changes. 26 January 1995
|
||||
|
||||
Copyright (C) 1992, 1993, 1994, 1995 Free Software Foundation, Inc.
|
||||
See the end for copying conditions.
|
||||
|
||||
Please send GNU C library bug reports to bug-glibc@prep.ai.mit.edu.
|
||||
|
||||
Version 1.10
|
||||
|
||||
* The library has changed from using GNU ld symbol aliases to using weak
|
||||
symbols where available. The ELF object file format supports weak
|
||||
symbols; GNU ld also supports weak symbols in the a.out format. (There
|
||||
is also now support for other GNU ld extensions in ELF. Use the
|
||||
`--with-elf' option to configure to indicate you have elf, and
|
||||
`--with-gnu-ld' if using GNU ld.) This changed resulted in the deletion
|
||||
of many files which contained only symbol aliases, reducing the size of
|
||||
the source and the compiled library; many other files were renamed to
|
||||
less cryptic names previously occupied by the symbol alias files.
|
||||
|
||||
* The pgrp functions have been regularized, slightly incompatibly but much
|
||||
less confusingly. The core functions are now `getpgid' and `setpgid',
|
||||
which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
|
||||
argument) and BSD `setpgrp' (identical to `setpgid') functions are
|
||||
provided for compatibility. There is no longer an incompatible `getpgrp'
|
||||
with an argument declared under _BSD_SOURCE; no BSD code uses it.
|
||||
|
||||
* The new header file <fts.h> and suite of functions simplify programs that
|
||||
operate on directory trees. This code comes from 4.4 BSD.
|
||||
|
||||
* Converted to Autoconf version 2, so `configure' has more options.
|
||||
Run `configure --help' to see the details.
|
||||
|
||||
* The resolver code has been updated from the BIND-4.9.3-BETA14 release.
|
||||
|
||||
* The new function `malloc_find_object_address' finds the starting address
|
||||
of a malloc'd block, given any address within the block. This can be
|
||||
useful for debugging.
|
||||
|
||||
* The new functions `strtoq' and `strtouq' parse integer values from
|
||||
strings, like `strtol' and `strtoul', but they return `long long int' and
|
||||
`unsigned long long int' values, respectively (64-bit quantities).
|
||||
|
||||
* There is a new malloc debugging hook `__memalign_hook'.
|
||||
|
||||
* There are new typedefs `ushort' for `unsigned short int' and `uint' for
|
||||
`unsigned int' in <sys/types.h>. These are for compatibility only and
|
||||
their use is discouraged.
|
||||
|
||||
* The `-lmcheck' library to enable standard malloc debugging hooks is now
|
||||
done differently, so that it works even without GNU ld.
|
||||
|
||||
Version 1.09
|
||||
|
||||
* For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
|
||||
|
||||
* New header file <fstab.h> and new functions `getfsspec', `getfsent' and
|
||||
friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
|
||||
|
||||
* The new function `daemon' from 4.4 BSD is useful for server programs that
|
||||
want to put themselves in the background.
|
||||
|
||||
* Joel Sherrill has contributed support for several standalone boards that
|
||||
run without an operating system.
|
||||
|
||||
* `printf', `scanf' and friends now accept a `q' type modifier for long
|
||||
long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
|
||||
|
||||
* All of the code taken from BSD (notably most of the math and networking
|
||||
routines) has been updated from the BSD 4.4-Lite release.
|
||||
|
||||
* The resolver code has been updated from the BIND-4.9.3-BETA9 release.
|
||||
|
||||
* The new functions `getdomainname' and `setdomainname' fetch or change the
|
||||
YP/NIS domain name. These are system calls which exist on systems which
|
||||
have YP (aka NIS).
|
||||
|
||||
* The time zone data files have been updated for the latest international
|
||||
conventions.
|
||||
|
||||
* The SunRPC programs `portmap' and `rpcinfo' are now installed in
|
||||
$(sbindir) (usually /usr/local/sbin) instead of $(bindir).
|
||||
|
||||
Version 1.08
|
||||
|
||||
* The C library now includes support for Sun RPC, from Sun's free
|
||||
RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
|
||||
are included. (There is still no support for YP.)
|
||||
|
||||
* Tom Quinn has contributed a port of the C library to SGI machines running
|
||||
Irix 4 (mips-sgi-irix4).
|
||||
|
||||
* The new `lockf' function is a simplified interface to the locking
|
||||
facilities of `fcntl', included for compatibility.
|
||||
|
||||
* New time functions `timegm', `timelocal', and `dysize' for compatibility.
|
||||
|
||||
* New header file <sys/timeb.h> and new function `ftime' for compatibility.
|
||||
|
||||
* New header files <poll.h> and <sys/poll.h> and new function `poll' for
|
||||
compatibility.
|
||||
|
||||
* The error message printed by `assert' for a failed assertion now includes
|
||||
the name of the program (if using GNU ld) and the name of the calling
|
||||
function (with versions of GCC that support this).
|
||||
|
||||
* The `psignal' function is now declared in <signal.h>, not <stdio.h>.
|
||||
|
||||
* The library now includes the <sys/mman.h> header file and memory
|
||||
management functions `mmap', `munmap', `mprotect', `msync', and
|
||||
`madvise', on systems that support those facilities.
|
||||
|
||||
* The interface for `mcheck' has changed slightly: the function called to
|
||||
abort the program when an allocation inconsistency is detected now takes
|
||||
an argument that indicates the type of failure. The new function
|
||||
`mprobe' lets you request a consistency check for a particular block at
|
||||
any time (checks are normally done only when you call `free' or `realloc'
|
||||
on a block).
|
||||
|
||||
* It is now possible to easily cross-compile the C library, building on one
|
||||
system a library to run on another machine and/or operating system. All
|
||||
you need to do is set the variable `HOST_CC' in `configparms' to the
|
||||
native compiler for programs to run on the machine you are building on (a
|
||||
few generator programs are used on Unix systems); set `CC' to the
|
||||
cross-compiler.
|
||||
|
||||
* The new function `fexecve' (only implemented on the GNU system) executes
|
||||
a program file given a file descriptor already open on the file.
|
||||
|
||||
Version 1.07
|
||||
|
||||
* Brendan Kehoe has contributed most of a port to the DEC Alpha
|
||||
running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
|
||||
|
||||
* You can set the variable `libprefix' in `configparms' to specify a prefix
|
||||
to be prepended to installed library files; this makes it easy to install
|
||||
the GNU C library to be linked as `-lgnuc' or whatever.
|
||||
|
||||
* The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
|
||||
copies a limited number of characters from a string, and returns the
|
||||
address of the last character written.
|
||||
|
||||
* You no longer need to check for whether the installed `stddef.h' is
|
||||
compatible with the GNU C library. configure now checks for you.
|
||||
|
||||
* You can now define a per-stream `fileno' function to convert the
|
||||
stream's cookie into an integral file descriptor.
|
||||
|
||||
* ``malloc (0)'' no longer returns a null pointer. Instead, it
|
||||
allocates zero bytes of storage, and returns a unique pointer which
|
||||
you can pass to `realloc' or `free'. The behavior is undefined if
|
||||
you dereference this pointer.
|
||||
|
||||
* The C library now runs on Sony NEWS m68k machines running either
|
||||
NewsOS 3 or NewsOS 4.
|
||||
|
||||
* The new `syscall' function is a system-dependent primitive function
|
||||
for invoking system calls. It has the canonical behavior on Unix
|
||||
systems, including unreliable return values for some calls (such as
|
||||
`pipe', `fork' and `getppid').
|
||||
|
||||
* The error code `EWOULDBLOCK' is now obsolete; it is always defined
|
||||
to `EAGAIN', which is the preferred name. On systems whose kernels
|
||||
use two distinct codes, the C library now translates EWOULDBLOCK to
|
||||
EAGAIN in every system call function.
|
||||
|
||||
Version 1.06
|
||||
|
||||
* The GNU C Library Reference Manual is now distributed with the library.
|
||||
`make dvi' will produce a DVI file of the printed manual.
|
||||
`make info' will produce Info files that you can read on line using C-h i
|
||||
in Emacs or the `info' program.
|
||||
Please send comments on the manual to bug-glibc-manual@prep.ai.mit.edu.
|
||||
|
||||
* The library now supports SVR4 on i386s (i386-unknown-sysv4).
|
||||
|
||||
* Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
|
||||
|
||||
* Jason Merrill has contributed a port to the Sequent Symmetry running
|
||||
Dynix version 3 (i386-sequent-dynix).
|
||||
|
||||
* The library has been ported to i386s running SCO 3.2.4 (also known as SCO
|
||||
ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
|
||||
|
||||
* New function `memory_warnings' lets you arrange to get warnings when
|
||||
malloc is running out of memory to allocate, like Emacs gives you.
|
||||
|
||||
* The C library now contains the relocating allocator used in Emacs 19 for
|
||||
its editing buffers. This allocator (ralloc) minimizes allocation
|
||||
overhead and fragmentation by moving allocated regions around whenever it
|
||||
needs to. You always refer to a ralloc'd region with a "handle" (a
|
||||
pointer to a pointer--an object of type `void **').
|
||||
|
||||
* There is a new `printf' format: `%m' gives you the string corresponding
|
||||
to the error code in `errno'.
|
||||
|
||||
* In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
|
||||
or `%[' conversion, but instead of filling in a fixed-sized buffer you
|
||||
pass, the `a' modifier says to fill in a `char **' you pass with a
|
||||
malloc'd string.
|
||||
|
||||
* The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
|
||||
`FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
|
||||
name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
|
||||
|
||||
* `mkstemp' is a traditional Unix function to atomically create and open a
|
||||
uniquely-named temporary file.
|
||||
|
||||
Version 1.05
|
||||
|
||||
* The standard location for the file that says what the local timezone is
|
||||
has changed again. It is now `/usr/local/etc/localtime' (or more
|
||||
precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
|
||||
|
||||
* The distribution no longer contains any files with names longer than 14
|
||||
characters.
|
||||
|
||||
* `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
|
||||
These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
|
||||
|
||||
* New functions `ttyslot' and `syslog' from 4.4 BSD.
|
||||
|
||||
Version 1.04
|
||||
|
||||
* The configuration process has changed quite a bit. The `configure'
|
||||
script is now used just like the configuration scripts for other GNU
|
||||
packages. The `sysdeps' directory hierarchy is much rearranged.
|
||||
The file `INSTALL' explains the new scheme in detail.
|
||||
|
||||
* The header files no longer need to be processed into ANSI C and
|
||||
traditional C versions. There is just one set of files to install, and
|
||||
it will work with ANSI or old C compilers (including `gcc -traditional').
|
||||
|
||||
* Brendan Kehoe and Ian Lance Taylor have ported the library to the
|
||||
MIPS DECStation running Ultrix 4.
|
||||
|
||||
* The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
|
||||
Tom Quinn contributed the initial code. The GNU C library can NOT yet be
|
||||
made itself into a shared library.
|
||||
|
||||
* Yet further improved support for the i386, running 4.3 BSD-like systems
|
||||
(such as Mach 3 with the Unix single-server), or System V.
|
||||
|
||||
* New function `strncasecmp' to do case-insensitive string comparison
|
||||
with limited length.
|
||||
|
||||
* New function `strsep' is a reentrant alternative to `strtok'.
|
||||
|
||||
* New functions `scandir' and `alphasort' for searching directories.
|
||||
|
||||
* New function `setenv' is a better interface to `putenv'.
|
||||
|
||||
* Ian Lance Taylor has contributed an implementation of the SVID `ftw'
|
||||
function for traversing a directory tree.
|
||||
|
||||
* The GNU obstack package is now also part of the C library.
|
||||
The new function `open_obstack_stream' creates a stdio stream that
|
||||
writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
|
||||
formatted output directly to an obstack.
|
||||
|
||||
* Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
|
||||
cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
|
||||
|
||||
* `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
|
||||
|
||||
* The new functions `strfry' and `memfrob' do mysterious and wonderful
|
||||
things to your strings.
|
||||
|
||||
* There are some new test programs: test-fseek, testmb, and testrand.
|
||||
|
||||
* Some work has been done to begin porting the library to 4.4 BSD and Linux.
|
||||
These ports are not finished, but are a good starting place for really
|
||||
supporting those systems.
|
||||
|
||||
* `/etc/localtime' is now the standard location for the file that says what
|
||||
the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
|
||||
This follows the general principle that `/etc' is the place for all local
|
||||
configuration files.
|
||||
|
||||
* The C library header files now use `extern "C"' when used by the C++
|
||||
compiler, so the C library should now work with C++ code.
|
||||
|
||||
* The header file <bstring.h> is gone. <string.h> now declares bcopy,
|
||||
bcmp, bzero, and ffs.
|
||||
|
||||
* Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
|
||||
function which uses the `merge sort' algorithm, and is said to be
|
||||
significantly faster than the old GNU `qsort' function. Merge sort is
|
||||
now the standard `qsort' function. The new algorithm can require a lot
|
||||
of temporary storage; so, the old sorting function is called when the
|
||||
required storage is not available.
|
||||
|
||||
* The C library now includes Michael Glad's Ultra Fast Crypt, which
|
||||
provides the Unix `crypt' function, plus some other entry points.
|
||||
Because of the United States export restriction on DES implementations,
|
||||
we are distributing this code separately from the rest of the C library.
|
||||
There is an extra distribution tar file just for crypt; it is called
|
||||
`glibc-VERSION-crypt.tar.Z', e.g. `glibc-1.04-crypt.tar.Z'. You can just
|
||||
unpack the crypt distribution along with the rest of the C library and
|
||||
build; you can also build the library without getting crypt. Users
|
||||
outside the USA can get the crypt distribution via anonymous FTP from
|
||||
ftp.uni-c.dk [129.142.6.74], or another archive site outside the U.S.
|
||||
|
||||
* The code and header files taken from 4.4 BSD have been updated with the
|
||||
latest files released from Berkeley.

Feature Test Macros
|
||||
-------------------
|
||||
|
||||
The exact set of features available when you compile a source file
|
||||
is controlled by which "feature test macros" you define.
|
||||
|
||||
If you compile your programs using `gcc -ansi', you get only the
|
||||
ANSI C library features, unless you explicitly request additional
|
||||
features by defining one or more of the feature macros. *Note GNU CC
|
||||
Command Options: (gcc.info)Invoking GCC, for more information about GCC
|
||||
options.
|
||||
|
||||
You should define these macros by using `#define' preprocessor
|
||||
directives at the top of your source code files. These directives
|
||||
*must* come before any `#include' of a system header file. It is best
|
||||
to make them the very first thing in the file, preceded only by
|
||||
comments. You could also use the `-D' option to GCC, but it's better
|
||||
if you make the source files indicate their own meaning in a
|
||||
self-contained way.
|
||||
|
||||
- Macro: _POSIX_SOURCE
|
||||
If you define this macro, then the functionality from the POSIX.1
|
||||
standard (IEEE Standard 1003.1) is available, as well as all of the
|
||||
ANSI C facilities.
|
||||
|
||||
- Macro: _POSIX_C_SOURCE
|
||||
If you define this macro with a value of `1', then the
|
||||
functionality from the POSIX.1 standard (IEEE Standard 1003.1) is
|
||||
made available. If you define this macro with a value of `2',
|
||||
then both the functionality from the POSIX.1 standard and the
|
||||
functionality from the POSIX.2 standard (IEEE Standard 1003.2) are
|
||||
made available. This is in addition to the ANSI C facilities.
|
||||
|
||||
- Macro: _BSD_SOURCE
|
||||
If you define this macro, functionality derived from 4.3 BSD Unix
|
||||
is included as well as the ANSI C, POSIX.1, and POSIX.2 material.
|
||||
|
||||
Some of the features derived from 4.3 BSD Unix conflict with the
|
||||
corresponding features specified by the POSIX.1 standard. If this
|
||||
macro is defined, the 4.3 BSD definitions take precedence over the
|
||||
POSIX definitions.
|
||||
|
||||
Due to the nature of some of the conflicts between 4.3 BSD and
|
||||
POSIX.1, you need to use a special "BSD compatibility library"
|
||||
when linking programs compiled for BSD compatibility. This is
|
||||
because some functions must be defined in two different ways, one
|
||||
of them in the normal C library, and one of them in the
|
||||
compatibility library. If your program defines `_BSD_SOURCE', you
|
||||
must give the option `-lbsd-compat' to the compiler or linker when
|
||||
linking the program, to tell it to find functions in this special
|
||||
compatibility library before looking for them in the normal C
|
||||
library.
|
||||
|
||||
- Macro: _SVID_SOURCE
|
||||
If you define this macro, functionality derived from SVID is
|
||||
included as well as the ANSI C, POSIX.1, and POSIX.2 material.
|
||||
|
||||
- Macro: _GNU_SOURCE
|
||||
If you define this macro, everything is included: ANSI C, POSIX.1,
|
||||
POSIX.2, BSD, SVID, and GNU extensions. In the cases where POSIX.1
|
||||
conflicts with BSD, the POSIX definitions take precedence.
|
||||
|
||||
If you want to get the full effect of `_GNU_SOURCE' but make the
|
||||
BSD definitions take precedence over the POSIX definitions, use
|
||||
this sequence of definitions:
|
||||
|
||||
#define _GNU_SOURCE
|
||||
#define _BSD_SOURCE
|
||||
#define _SVID_SOURCE
|
||||
|
||||
Note that if you do this, you must link your program with the BSD
|
||||
compatibility library by passing the `-lbsd-compat' option to the
|
||||
compiler or linker. *Note:* If you forget to do this, you may get
|
||||
very strange errors at run time.
|
||||
|
||||
We recommend you use `_GNU_SOURCE' in new programs. If you don't
|
||||
specify the `-ansi' option to GCC and don't define any of these macros
|
||||
explicitly, the effect is the same as defining `_GNU_SOURCE'.
|
||||
|
||||
When you define a feature test macro to request a larger class of
|
||||
features, it is harmless to define in addition a feature test macro for
|
||||
a subset of those features. For example, if you define
|
||||
`_POSIX_C_SOURCE', then defining `_POSIX_SOURCE' as well has no effect.
|
||||
Likewise, if you define `_GNU_SOURCE', then defining either
|
||||
`_POSIX_SOURCE' or `_POSIX_C_SOURCE' or `_SVID_SOURCE' as well has no
|
||||
effect.
|
||||
|
||||
Note, however, that the features of `_BSD_SOURCE' are not a subset of
|
||||
any of the other feature test macros supported. This is because it
|
||||
defines BSD features that take precedence over the POSIX features that
|
||||
are requested by the other macros. For this reason, defining
|
||||
`_BSD_SOURCE' in addition to the other feature test macros does have an
|
||||
effect: it causes the BSD features to take priority over the conflicting
|
||||
POSIX features.

This directory contains the version 1.09.5 test release of the GNU C Library.
|
||||
Many bugs have been fixed since the last release.
|
||||
Some bugs surely remain.
|
||||
|
||||
As of this release, the GNU C library has been ported to the following
|
||||
configurations:

alpha-dec-osf1
|

i386-bsd4.3

Porting the library is not hard. If you are interested in doing a port,
|

please get on the mailing list by sending electronic mail to
|
||||
bug-glibc-request@prep.ai.mit.edu.
|
||||
|
||||
The GNU C library now includes Michael Glad's Ultra Fast Crypt, which
|
||||
provides the Unix `crypt' function, plus some other entry points.
|
||||
Because of the United States export restriction on DES implementations,
|
||||
we are distributing this code separately from the rest of the C
|
||||
library. There is an extra distribution tar file just for crypt; it is
|
||||
called `glibc-1.09.5-crypt.tar.gz'. You can just unpack the crypt
|
||||
distribution along with the rest of the C library and build; you can
|
||||
also build the library without getting crypt. Users outside the USA
|
||||
can get the crypt distribution via anonymous FTP from ftp.uni-c.dk
|
||||
[129.142.6.74], or another archive site outside the USA. Archive
|
||||
maintainers are encouraged to copy this distribution to their archives
|
||||
outside the USA. Please get it from ftp.uni-c.dk; transferring this
|
||||
distribution from prep.ai.mit.edu (or any other site in the USA) to a
|
||||
site outside the USA is in violation of US export laws.
|
||||
|
||||
See the file INSTALL to find out how to configure, build, install, and port
|
||||
the GNU C library.
|
||||
|
||||
The GNU C Library is completely documented by the Texinfo manual found
|
||||
in the `manual/' subdirectory. The manual is still being updated and
|
||||
contains some known errors and omissions; we regret that we do not have
|
||||
the resources to work on the manual as much as we would like. Please
|
||||
send comments on the manual to bug-glibc-manual@prep.ai.mit.edu, and
|
||||
not to the library bug-reporting address.
|
||||
|
||||
The file NOTES contains a description of the feature-test macros used
|
||||
in the GNU C library, explaining how you can tell the library what
|
||||
facilities you want it to make available.

ARGLIST lists the arguments, separated by commas and enclosed in

|

ARGS list the arguments with their types. It becomes a prototype in

In ANSI C it is `NAMEPROTOTYPE' (so PROTOTYPE should be enclosed in

For a function that takes no arguments, PROTOTYPE should be `(NOARGS)'.

The GNU C library now includes Michael Glad's Ultra Fast Crypt, which
|
||||
provides the Unix `crypt' function, plus some other entry points. Because
|
||||
of the United States export restriction on DES implementations, we are
|
||||
distributing this code separately from the rest of the C library. There is
|
||||
an extra distribution tar file just for crypt; it is called
|
||||
`glibc-1.07-crypt.tar.gz'. You can just unpack the crypt distribution
|
||||
along with the rest of the C library and build; you can also build the
|
||||
library without getting crypt. Users outside the USA can get the crypt
|
||||
distribution via anonymous FTP from ftp.uni-c.dk [129.142.6.74], or another
|
||||
archive site outside the USA. Archive maintainers are encouraged to copy
|
||||
this distribution to their archives outside the USA. Please get it from
|
||||
ftp.uni-c.dk; transferring this distribution from prep.ai.mit.edu (or any
|
||||
other site in the USA) to a site outside the USA is in violation of US
|
||||
export laws.

|

Status of Hurd support in libc. Last updated 22 Nov 1994.
|
||||
Roland McGrath <roland@gnu.ai.mit.edu>
|
||||
|
||||
Everything not noted below is implemented, most of it tested. There are
|
||||
various very small things unfinished or thought to be perhaps wrong
|
||||
throughout the code, marked by comments containing `XXX'.
|
||||
|
||||
|
||||
* Signals and job control work, but are a very hairy area.
|
||||
There are various ways the signal thread can block and fail
|
||||
to respond when the program is losing badly.
|
||||
|
||||
* We are not sure about possible races between setpgrp (A, pgrp) from
|
||||
process B vs process A receiving proc_newids.
|
||||
|
||||
* The rest of libc (stdio et al) is not safe for multithreaded programs.
|
||||
mutex locks should be added to various things.
|
||||
|
||||
* Recovery from faults in the signal thread is not implemented yet.
|
||||
|
||||
* longjmp needs to clean up reply port, intr_port; needs thought about.
|
||||
|
||||
* Cooperation with cthreads is not finished. If you link with cthreads,
|
||||
libc internal code still does not use real condition variables.
|
||||
sigsuspend currently does a busy wait where it should use a condition.
|
||||
Signal state is per kernel thread; for unwired cthreads it should be per
|
||||
cthread instead.
|
||||
|
||||
* sigaltstack/sigstack do not really work: the signal stack needs thread
|
||||
variables and cthread data set up, which is not done.
|
||||
|
||||
* malloc is a kludge.
|
||||
|
||||
* Nothing uses mapped io. Eventually stdio and read/write/seek should. I
|
||||
have written a little code for this, but it is far from finished.
|
||||
|
||||
* Resource limits do not really work; current implementation is patchy and
|
||||
inconsistent.
|
||||
|
||||
* libc implicitly uses some environment variables. This is a security
|
||||
problem for setuid exec. Probably crt0 should remove the variables from
|
||||
the environment if setuid.
|
||||
|
||||
* The miscellaneous msg.defs calls are only partially implemented.
|
||||
|
||||
* The default SIGINFO handler needs to be written.
|
||||
|
||||
* File locking is not implemented; the RPC interface is not there yet.
|
||||
|
||||
* The current getitimer/setitimer implementation is a kludge.
|
||||
|
||||
* mmap cannot do MAP_NOEXTEND.
|
||||
|
||||
* Unimplemented calls (from the 4.4 system call list):
|
||||
acct
|
||||
fstatfs
|
||||
getfh
|
||||
getfsstat
|
||||
getrusage
|
||||
