Optional

libxcb-1.4 and LessTif-0.95.2

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/mesalib

Installation of MesaLib

Extract both tarballs from the same top-level directory as both will extract to the Mesa-7.6 directory.

Install MesaLib by running the following commands: 

sed 's@FLAGS=\"-g@FLAGS=\"@' -i configure &&
./configure $XORG_CONFIG &&
make

This package does not come with a test suite.

Now, as the root user: 

make install

If you built the demo programs, install them using the following command as the root user: 

install -v -m755 progs/xdemos/glx{info,gears} ${XORG_PREFIX}/bin

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

Command Explanations

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).
