|

[A1] {UD} This is difficult to answer. The file `README' lists the
|
||||
architectures GNU libc is known to run *at some time*. This does not
|
||||
mean that it still can be compiled and run on them in the moment.

[Q8] ``I expect GNU libc to be 100% source code compatible with
|
||||
the old Linux based GNU libc. Why isn't it like this?''
|
||||
|
||||
[A8] {DMT} Not every extension in Linux libc's history was well
|
||||
thought. In fact it had a lot of problems with standard compliance
|
||||
and cleanliness. With the introduction of a new version number these
|
||||
errors now can be corrected. The following list shows a list of the
|
||||
know source code incompatibilities.
|
||||
|
||||
* _GNU_SOURCE: glibc does not automatically define _GNU_SOURCE. Thus,
|
||||
if a program depends on GNU extensions, it is necessary
|
||||
to compile it with C compiler option -D_GNU_SOURCE. This difference
|
||||
normally mainfests itself in the form of missing prototypes and/or
|
||||
data type definitions. Thus, if you get such errors, the first thing you
|
||||
should do is grep the header files in /usr/include and /usr/include/sys
|
||||
to check whether the functions are really missing or whether it is
|
||||
just necessary to add a define of _GNU_SOURCE. Similar comments apply
|
||||
to _BSD_SOURCE, _POSIX_SOURCE, _SVID_SOURCE etc (see
|
||||
/usr/include/features.h).
|
||||
|
||||
* reboot(): GNU libc sanitizes the interface of reboot() to be more
|
||||
compatible with the interface used on other OSes. In particular,
|
||||
reboot() as implemented in glibc takes just one argument. This argument
|
||||
corresponds to the third argument of the Linux reboot system call.
|
||||
That is, a call of the form reboot(a, b, c) needs to be changed into
|
||||
reboot(c).
|
||||
|
||||
* errno: If a program uses variable "errno", then it _must_ include header
|
||||
file <errno.h>. The old libc often (erroneously) declared this variable
|
||||
implicitly as a side-effect of including other libc header files. glibc
|
||||
is careful to avoid such namespace pollution, which, in turn, means that
|
||||
you really need to include the header files that you depend on. This
|
||||
difference normally manifests itself in the form of the compiler
|
||||
complaining about the references of the undeclared symbol "errno".
|
||||
|
||||
* Linux-specific syscalls: All Linux system calls now have appropriate
|
||||
library wrappers and corresponding declarations in various header files.
|
||||
This is because the syscall() macro that was traditionally used to
|
||||
work around missing syscall wrappers are inherently non-portable and
|
||||
error-prone. The following tables lists all the new syscall stubs,
|
||||
the header-file declaring their interface and the system call name.
|
||||
|
||||

get_kernel_syms get_kernel_syms <sys/module.h>
|
||||
init_module init_module <sys/module.h>
|
||||
syslog ksyslog_ctl <unistd.h>
|
||||
|
||||
To get the Linux-specific declarations in <unistd.h>, you'll need
|
||||
to define C pre-processor macro _LINUX_SOURCE during compilation.
