User Notes: Unlike other packages, the MesaLib-&mesalib-version;.tar.bz2 archive will extract to the Mesa-&mesalib-version; directory. Install MesaLib by running the following commands: sed 's@FLAGS=\"-g@FLAGS=\"@' -i configure && patch -Np1 -i ../MesaLib-&mesalib-version;-add_xdemos-2.patch && patch -Np1 -i ../MesaLib-&mesalib-version;-llvm-3.1-fixes-1.patch && ./configure --prefix=$XORG_PREFIX \ --enable-texture-float \ --enable-gles1 \ --enable-gles2 \ --enable-xa \ --enable-shared-glapi \ --enable-shared-dricore \ --enable-glx-tls \ --with-gallium-drivers="nouveau,r300,r600,svga,swrast" && make This package does not come with a test suite. Now, as the root user: make install && mkdir -pv ${XORG_PREFIX}/share/doc/MesaLib-&mesalib-version; && cp -rfv docs/* ${XORG_PREFIX}/share/doc/MesaLib-&mesalib-version; Finally, if installing to any prefix other than /usr, you should create symlinks to the GL headers in /usr/include. Execute the following command as the root user: for GLHEADER in EGL GL GLES GLES2 KHR xa_composite.h xa_context.h xa_tracker.h do ln -sfv ${XORG_PREFIX}/include/${GLHEADER} /usr/include/${GLHEADER} done sed 's@FLAGS=\"-g@FLAGS=\"@' -i configure: by default, Mesa builds with debugging symbols. Remove the -g switch from both CFLAGS and CXXFLAGS with this command. --enable-texture-float: This switch enables floating-point textures and renderbuffers. Please consult docs/patents.txt to see if there are any legal issues if you use this feature. --enable-gles1: This switch enables support for OpenGL ES 1.x API. --enable-gles2: This switch enables support for OpenGL ES 2.x API. --enable-xa: This switch enables building of the XA X Acceleration API (Required for VMware 3D Driver). --enable-shared-glapi: This switch enables building of the shared glapi library. --enable-shared-dricore: This switch enables linking of the DRI modules with shared core DRI routines. --enable-glx-tls: This switch enables TLS support in GLX. --with-gallium-drivers="...": This parameter controls which Gallium drivers should be built. Available drivers are: i915, nouveau, r300, r600, swrast and svga. Note that you will need to remove r300 and r600 from the list if you haven't installed .
