Installation of MesaLib

[Note]

Note

Unlike other packages, the MesaLib-7.11.2.tar.bz2 archive will extract to the Mesa-7.11.2 directory.

Install MesaLib by running the following commands: 

sed 's@FLAGS=\"-g@FLAGS=\"@' -i configure &&
patch -Np1 -i ../MesaLib-7.11.2-llvm_3.0-1.patch   &&
patch -Np1 -i ../MesaLib-7.11.2-add_xdemos-2.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-7.11.2 &&
install -v -m644    docs/* \
                    ${XORG_PREFIX}/share/doc/MesaLib-7.11.2

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 &&
ln -s -v ${XORG_PREFIX}/include/EGL /usr/include &&
ln -s -v ${XORG_PREFIX}/include/KHR /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).

--with-gallium-driver=...: build additional gallium drivers. Defaults to r300, r600, and swrast. You must specify i9xx and nouveau drivers.
