This directory is an add-on for the GNU C Library (glibc).
It provides additional ports to machines and/or operating systems that are
not maintained in the official glibc source tree.
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.
The scripts in the top level of this directory provide the infrastructure
necessary for a glibc add-on. You can make a new add-on containing one or
more ports by copying configure, configure.in, and Makeconfig into your own
add-on directory, which you can give any name (it doesn't have to be
`ports'). 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.
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 the glibc CVS as a
module called "ports". See http://www.gnu.org/software/libc/resources.html
for details on using CVS. 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
@ -25,15 +36,8 @@ 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.
Like all glibc add-ons, the only way to use this is to place this directory
(just a symlink won't do) inside the top-level glibc source directory.
Then include the name of this directory (e.g. `ports') when you specify
`--enable-add-ons=...' to glibc's configure (or use just --enable-add-ons
to have it try every add-on directory sitting in your source tree).
If you find problems with the top-level scripts in this add-on, please go
to http://sources.redhat.com/bugzilla/ and file a report for the glibc
under the "admin" component.
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.
