MesaLib-10.6.6
Installation of MesaLib
If you have downloaded the xdemos patch (needed if testing the Xorg
installation per BLFS instructions), apply it by running the
following command:
patch -Np1 -i ../mesa-10.6.6-add_xdemos-1.patch
Install MesaLib by running the
following commands:
patch -Np1 -i ../mesa-10.6.6-llvm_3_7-1.patch &&
GLL_DRV="nouveau,r300,r600,radeonsi,svga,swrast" &&
./autogen.sh CFLAGS='-O2' CXXFLAGS='-O2' \
--prefix=$XORG_PREFIX \
--sysconfdir=/etc \
--enable-texture-float \
--enable-gles1 \
--enable-gles2 \
--enable-osmesa \
--enable-xa \
--enable-gbm \
--enable-glx-tls \
--with-egl-platforms="drm,x11" \
--with-gallium-drivers=$GLL_DRV &&
unset GLL_DRV &&
make
If you have applied the xdemos patch, build the demo programs by
running the following command:
make -C xdemos DEMOS_PREFIX=$XORG_PREFIX
To test the results, issue: make
check.
Now, as the root user:
make install
If you have built the demo programs, install them by running the
following command as the root user:
make -C xdemos DEMOS_PREFIX=$XORG_PREFIX install
If desired, install the optional documentation by running the
following commands as the root
user:
install -v -dm755 /usr/share/doc/mesa-10.6.6 &&
cp -rfv docs/* /usr/share/doc/mesa-10.6.6
Command Explanations
CFLAGS="-O2"
CXXFLAGS="-O2": By default, Autoconf sets CFLAGS and CXXFLAGS to "-g -O2".
That results in binaries and libraries being built with debugging
symbols which make them bigger. Override the default flags to omit
-g compiler flag so the final libraries are smaller.
--enable-texture-float:
This switch enables floating-point textures and render buffers.
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-osmesa: This
switch enables building of the libOSMesa library.
--enable-xa: This switch
enables building of the XA X Acceleration API (Required for VMware
3D Driver).
--enable-gbm: This switch
enables building of the Mesa
Graphics Buffer Manager library.
--enable-glx-tls: This
switch enables TLS (Thread Local Storage) support in GLX.
--with-egl-platforms="...":
This parameter controls which platforms EGL will be built for.
Available platforms are drm, x11 and wayland.
--with-gallium-drivers="...": This
parameter controls which Gallium3D drivers should be built.
Available drivers are: i915, ilo, nouveau, r300, r600, radeonsi,
svga and swrast. You will need to remove r300, r600 and radeonsi
from the list if you did not install elfutils and LLVM with the r600/amdgpu backend.
--enable-r600-llvm-compiler: Use this
switch to enable an experimental R600 LLVM backend for graphics shaders which claims
to speed up the driver.
--enable-sysfs: Use this switch to
enable simple PCI identification method, required for building DRI
on systems without udev.
