Two components of GNU Libc are distributed as "add-on" bundles
separate from the main distribution. Unless you are doing an unusual
installation, you should get them both. Support for the `crypt'
function is distributed separately because of US export restrictions.
If you are outside the US or Canada, you must get `crypt' support from
a site outside the US, such as `ftp.ifi.uio.no'. (Most non-US mirrors
of `ftp.gnu.org' will have it too.) The file you need is
`glibc-crypt-VERSION.tar.gz'. Support for POSIX threads is maintained
by someone else, so it's in a separate package. At the moment it is
only available for Linux systems; this will change in the future. Get

Features can be added to GNU Libc via "add-on" bundles. These are
separate tarfiles which you unpack into the top level of the source
tree. Then you give `configure' the `--enable-add-ons' option to
activate them, and they will be compiled into the library. As of the
2.1 release, two important components of glibc are distributed as
"official" add-ons. Unless you are doing an unusual installation, you

should always give this option. The `--prefix' option tells configure

If you give just one of these, `configure' will get confused. If
`configure' doesn't correctly guess your system type for a native
build, report that as a bug.
If you give just `--host', configure will prepare for a native
compile but use what you say instead of guessing what your system
is. This is most useful to change the CPU submodel. For example,
if configure guesses your machine as `i586-pc-linux-gnu' but you
want to compile a library optimized for 386es, give
`--host=i386-pc-linux-gnu' or just `--host=i386-linux'. (A
library compiled for a Pentium (`i586') will still work on a 386,
but it may be slower.)
If you give just `--build', configure will get confused.

Installing the C Library
========================
To install the library and its header files, and the Info files of
the manual, type `make install'. This will build things if necessary,
before installing them. If you want to install the files in a different
place than the one specified at configuration time you can specify a
value for the Makefile variable `install_root' on the command line.
This is useful to create chroot'ed environment or to prepare binary
releases.
before installing them. Don't rely on that; compile everything first.
If you are installing glibc as your primary C library, we recommend you
shut the system down to single-user mode first, and reboot afterward.
This minimizes the risk of breaking things when the library changes out
from underneath.
If you are upgrading from a previous installation of glibc 2.0 or
2.1, `make install' will do the entire job. If you're upgrading from
Linux libc5 or some other C library, you need to rename the old
`/usr/include' directory out of the way first, or you will end up with
a mixture of header files from both libraries, and you won't be able to
compile anything. You may also need to reconfigure GCC to work with
the new library. The easiest way to do that is to figure out the
compiler switches to make it work again
(`-Wl,-dynamic-linker=/lib/ld-linux.so.2' should work on Linux systems)
and use them to recompile gcc. You can also edit the specs file
(`/usr/lib/gcc-lib/TARGET/VERSION/specs'), but that is a bit of a black
art.
You can install glibc somewhere other than where you configured it
to go by setting the `install_root' variable on the command line for
`make install'. The value of this variable is prepended to all the
paths for installation. This is useful when setting up a chroot
environment or preparing a binary distribution.
Glibc 2.1 includes two daemons, `nscd' and `utmpd', which you may or
may not want to run. `nscd' caches name service lookups; it can
dramatically improve performance with NIS+, and may help with DNS as
well. `utmpd' allows programs that use the old format for the `utmp'
file to coexist with new programs. For more information see the files
`nscd/README' and `login/README.utmpd'.
One auxiliary program, `/usr/libexec/pt_chown', is installed setuid
`root'. This program is invoked by the `grantpt' function; it sets the
permissions on a pseudoterminal so it can be used by the calling
process. This means programs like `xterm' and `screen' do not have to
be setuid to get a pty. (There may be other reasons why they need
privileges.) If you are using a 2.1 Linux kernel with the `devptsfs'
or `devfs' filesystems providing pty slaves, you don't need this
program; otherwise you do. The source for `pt_chown' is in
`login/programs/pt_chown.c'.

If you are installing GNU libc on a Linux system, you need to have
the header files from a development kernel around for reference. You
do not need to use the development kernel, just have its headers where
glibc can get at them. The easiest way to do this is to unpack a
development kernel in a directory such as `/usr/src/linux-dev'. In that
directory, run `make config' and accept all the defaults. Then
configure glibc with the option
`--with-headers=/usr/src/linux-dev/include'. Use the latest
development kernel you can get your hands on.
An alternate tactic is to unpack the development kernel and run
`make config' as above. Then rename or delete `/usr/include', create a
new `/usr/include', and make the usual symbolic links of
`/usr/include/linux' and `/usr/include/asm' into the development kernel
sources. You can then configure glibc with no special options. This
tactic is recommended if you are upgrading from libc5, since you need
to get rid of the old header files anyway.
Note that `/usr/include/net' and `/usr/include/scsi' should *not* be
symlinks into the kernel sources. GNU libc provides its own versions
of these files.
Linux expects some components of the libc installation to be in
`/lib' and some in `/usr/lib'. This is handled automatically if you
configure glibc with `--prefix=/usr'. If you set some other prefix or
allow it to default to `/usr/local', then all the components are
installed there.
If you are upgrading from libc5, you need to recompile every shared
library on your system against the new library for the sake of new code,
but keep the old libraries around for old binaries to use. This is
complicated and difficult. Consult the Glibc2 HOWTO at
`http://www.imaxx.net/~thrytis/glibc' for details.
You cannot use `nscd' with 2.0 kernels, due to bugs in the
kernel-side thread support. `nscd' happens to hit these bugs
particularly hard, but you might have problems with any threaded
program.

To install the library and its header files, and the Info files of the

before installing them. If you want to install the files in a different
place than the one specified at configuration time you can specify a

before installing them. Don't rely on that; compile everything first.
If you are installing glibc as your primary C library, we recommend you
shut the system down to single-user mode first, and reboot afterward.
This minimizes the risk of breaking things when the library changes out
from underneath.
If you are upgrading from a previous installation of glibc 2.0 or 2.1,
@samp{make install} will do the entire job. If you're upgrading from
Linux libc5 or some other C library, you need to rename the old
@file{/usr/include} directory out of the way first, or you will end up
with a mixture of header files from both libraries, and you won't be
able to compile anything. You may also need to reconfigure GCC to work
with the new library. The easiest way to do that is to figure out the
compiler switches to make it work again
(@samp{-Wl,-dynamic-linker=/lib/ld-linux.so.2} should work on Linux
systems) and use them to recompile gcc. You can also edit the specs
file (@file{/usr/lib/gcc-lib/@var{TARGET}/@var{VERSION}/specs}), but
that is a bit of a black art.
You can install glibc somewhere other than where you configured it to go
by setting the @code{install_root} variable on the command line for
@samp{make install}. The value of this variable is prepended to all the
paths for installation. This is useful when setting up a chroot
environment or preparing a binary distribution.
Glibc 2.1 includes two daemons, @code{nscd} and @code{utmpd}, which you
may or may not want to run. @code{nscd} caches name service lookups; it
can dramatically improve performance with NIS+, and may help with DNS as
well. @code{utmpd} allows programs that use the old format for the
@file{utmp} file to coexist with new programs. For more information see
the files @file{nscd/README} and @file{login/README.utmpd}.
One auxiliary program, @file{/usr/libexec/pt_chown}, is installed setuid
@code{root}. This program is invoked by the @code{grantpt} function; it
sets the permissions on a pseudoterminal so it can be used by the
calling process. This means programs like @code{xterm} and
@code{screen} do not have to be setuid to get a pty. (There may be
other reasons why they need privileges.) If you are using a 2.1 Linux
kernel with the @code{devptsfs} or @code{devfs} filesystems providing
pty slaves, you don't need this program; otherwise you do. The source
for @file{pt_chown} is in @file{login/programs/pt_chown.c}.

If you are installing GNU libc on a Linux system, you need to have the
header files from a development kernel around for reference. You do not
need to use the development kernel, just have its headers where glibc
can get at them. The easiest way to do this is to unpack a development
kernel in a directory such as @file{/usr/src/linux-dev}. In that
directory, run @samp{make config} and accept all the defaults. Then
configure glibc with the option
@samp{--with-headers=/usr/src/linux-dev/include}. Use the latest
development kernel you can get your hands on.
An alternate tactic is to unpack the development kernel and run
@samp{make config} as above. Then rename or delete @file{/usr/include},
create a new @file{/usr/include}, and make the usual symbolic links of
@file{/usr/include/linux} and @file{/usr/include/asm} into the
development kernel sources. You can then configure glibc with no
special options. This tactic is recommended if you are upgrading from
libc5, since you need to get rid of the old header files anyway.
Note that @file{/usr/include/net} and @file{/usr/include/scsi} should
@strong{not} be symlinks into the kernel sources. GNU libc provides its
own versions of these files.
Linux expects some components of the libc installation to be in
@file{/lib} and some in @file{/usr/lib}. This is handled automatically
if you configure glibc with @samp{--prefix=/usr}. If you set some other
prefix or allow it to default to @file{/usr/local}, then all the
components are installed there.
If you are upgrading from libc5, you need to recompile every shared
library on your system against the new library for the sake of new code,
but keep the old libraries around for old binaries to use. This is
complicated and difficult. Consult the Glibc2 HOWTO at
@url{http://www.imaxx.net/~thrytis/glibc} for details.
You cannot use @code{nscd} with 2.0 kernels, due to bugs in the
kernel-side thread support. @code{nscd} happens to hit these bugs
particularly hard, but you might have problems with any threaded
program.
