I have added a few new configuration files to the configs directory:
There's a base configuration, debian, which sets things up for
building in a debian environment.
There's also a debian-static configuration, which is for static
building.
All the others are derived from one of these two configurations.
The platform-specific optimizations go into a debian-foo_ARCH file, like
debian_i386 or debian_sparc. You can name this files whatever you want,
but the last token must be a debian arch name. Note the "_"! These
will be picked up automatically by the debian/rules.
In order to actually install the new files, you need to edit
debian/libdir.map, the format is:
target-name libdir package package-dev
The architecture optimized libraries should go under
/usr/lib/<something>, where <something> matches the optimizations used,
e.g. "cmov" or "v9".
Only packages listed in the control file *and* libdir.map are actually
built. That means that even if debian/libdir.map lists
libgl1-random-stuff, if libgl1-random-stuff is *not* listed in
debian/control it *won't* be built. The other way around, if
libgl1-random-stuff is listed in debian/control but there's no entry for
it in debian/libdir.map it *won't* be built.
Again...
If the libdir.map file doesn't mention your (lib)-(config), e.g.
gl-debian_i386, THE TARGET WON'T BE BUILT.
If the package listed in libdir.map is not listed in debian/control, THE
TARGET WON'T BE BUILT.
For architectures where glide3 is available an extra package is built
(iff this is the mesa-legacy source package). The list of supported
architectures in found in the control file.
There's an alioth project for this package:
