This is the glibc ports repository, an add-on for the GNU C Library (glibc).
|
|
It contains code that is not maintained in the official glibc source tree.
|
|
|
|
This includes working ports to GNU/Linux on some machine architectures that
|
|
are not maintained in the official glibc source tree. It also includes
|
|
some code once used by old libc ports now defunct, which has been abandoned
|
|
but may be useful for some future porter to examine. It may also include
|
|
some optimized functions tailored for specific CPU implementations of an
|
|
architecture, to be selected using --with-cpu.
|
|
|
|
The ports repository is cooperatively maintained by volunteers on the
|
|
<libc-ports@sourceware.org> mailing list, and housed in a separate
|
|
ports git repository. See
|
|
http://www.gnu.org/software/libc/download.html for details on using
|
|
git. To report a bug in code housed in the ports repository, please
|
|
go to http://sources.redhat.com/bugzilla/ and file a bug report under
|
|
the glibc "ports" component.
|
|
|
|
An add-on for an individual port can be made from just the sysdeps/
|
|
subdirectories containing the port's code. You may want to include a
|
|
README and Banner of your own talking about your port's code in particular,
|
|
rather than the generic ones here.
|
|
|
|
The real source code for any ports is found in the sysdeps/ subdirectories.
|
|
These should be exactly what would go into the main libc source tree if you
|
|
were to incorporate it directly. The only exceptions are the files
|
|
sysdeps/*/preconfigure and sysdeps/*/preconfigure.in; these are fragments
|
|
used by this add-on's configure fragment. The purpose of these is to set
|
|
$base_machine et al when the main libc configure's defaults are not right
|
|
for some machine. Everything else can and should be done from a normal
|
|
sysdeps/.../configure fragment that is used only when the configuration
|
|
selects that sysdeps subdirectory. Each port that requires some special
|
|
treatment before the sysdeps directory list is calculated, should add a
|
|
sysdeps/CPU/preconfigure file; this can either be written by hand or
|
|
generated by Autoconf from sysdeps/CPU/preconfigure.in, and follow the
|
|
rules for glibc add-on configure fragments. No preconfigure file should do
|
|
anything on an unrelated configuration, so that disparate ports can be put
|
|
into a single add-on without interfering with each other. Files that
|
|
would go in scripts/data/ for libc go in data/ in ports.
|
|
|
|
Like all glibc add-ons, this must be used by specifying the directory in
|
|
the --enable-add-ons option when running glibc's configure script.
|
|
|
|
The GNU C Library is free software. See the file COPYING.LIB in the
|
|
libc repository for copying conditions, and LICENSES for notices about
|
|
a few contributions that require these additional notices to be
|
|
distributed. License copyright years may be listed using range
|
|
notation, e.g., 2000-2011, indicating that every year in the range,
|
|
inclusive, is a copyrightable year that would otherwise be listed
|
|
individually.
