Install MesaLib by running the following commands: sed 's@FLAGS=\"-g@FLAGS=\"@' -i configure && patch -Np1 -i ../MesaLib-&mesalib-version;-add_xdemos-1.patch && ./configure $XORG_CONFIG --enable-xcb && make This package does not come with a test suite. Now, as the root user: make install && install -v -m755 -d ${XORG_PREFIX}/share/doc/MesaLib-&mesalib-version; && install -v -m644 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: ln -s -v ${XORG_PREFIX}/include/GL /usr/include 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-xcb: use the XCB backend instead of the default XLib backend for GLX. --enable-motif: build motif widgets into the GL widgets library (requires lesstif).
