ToaruOS previously shipped with these demos - gears and teapot - as part of the base distribution, but as they were the only uses of Mesa in the standard build and no additional Mesa-based software has been ported to ToaruOS, it was decided that these would be better left as a package. Mesa weighs in at about 3MB, so it's a big thing to be including on the base live CD image with only these demos to show.

The only known-working version of Mesa is 7.5.2, which is very old (late September, 2009). It was rather arbitrarily chosen because it includes the pre-Gallium swrast software rasterizer in a form that manages to build with our Newlib. Later versions may still work. If you manage to build a Mesa newer than this, please let me know as I would love to update (something 8.x or newer would be very nice for the OpenGL 3.0 support).

1. Obtain Mesa - possibly from our mirror, as the actual Mesa site may not even have this particular version anymore.

2. Patch the config.sub to accept -toaru*.

3. Build it:

    ./configure --enable-32-bit --host=$TARGET --prefix=$VIRTPREFIX  --with-osmesa-bits=8 --with-driver=osmesa  --disable-egl --disable-shared --without-x --disable-glw --disable-glut --disable-driglx-direct --disable-gallium
    make
    make DESTDIR=$TOARU_SYSROOT install
   

4. Build libOSMesa.so from libOSMesa.a (depends on -lm; see the core Toaru Makefile if you don't know how to do this)
