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.
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
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.
