Beyond Linux® From Scratch (systemd edition) - Version 7.10

Chapter 24. X Window System Environment

Mesa-12.0.1

Introduction to Mesa

Mesa is an OpenGL compatible 3D graphics library.

This package is known to build and work properly using an LFS-7.10 platform.

Package Information

Additional Downloads

Mesa Dependencies

Required

Xorg Libraries, libdrm-2.4.70, and Python-2.7.12

Recommended

elfutils-0.167 (required for Gallium3D radeonsi driver), libva-1.7.1 (to build drivers for supported hardware, note that there is a circular dependency. You must build libva first without EGL and GLX support, install this package, and rebuild libva.), libvdpau-1.1.1 (to build VDPAU drivers), LLVM-3.8.1 (required for Gallium3D r300, r600 and radeonsi drivers and also for llvmpipe which is intended to be the fastest of the three sw rasterizers, see http://www.mesa3d.org/faq.html#part3)

Optional

libgcrypt-1.7.3, Nettle-3.2, (Wayland-1.11.0 required for Plasma-5.7.3 and for GNOME), mesa-demos (provides more than 300 extra demos to test Mesa; this includes the same programs added by the patch above), and Bellagio OpenMAX Integration Layer (for mobile platforms)

[Note]

Note

The instructions below assume that elfutils and LLVM with the r600/amdgpu and host backends are installed. You will need to modify the instructions if you choose not to install them. Please note that elfutils and LLVM are required for the Gallium3D r300, r600, radeonsi, and SWR drivers. For an explanation of Gallium3D please see https://en.wikipedia.org/wiki/Gallium3D.

Installation of Mesa

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-12.0.1-add_xdemos-1.patch

Install Mesa by running the following commands:

[Note]

Note

Add wayland to the --with-egl-platforms option below if you plan on building Plasma-5.7.3 or GNOME. 

GLL_DRV="nouveau,r300,r600,radeonsi,svga,swrast,swr" &&

sed -i "/pthread-stubs/d" configure.ac      &&
sed -i "/seems to be moved/s/^/: #/" bin/ltmain.sh &&
./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-12.0.1 &&
cp -rfv docs/* /usr/share/doc/mesa-12.0.1

Command Explanations

sed -i ... configure.ac: This sed removes a dependency on the libpthread-stubs package which is useless on Linux.

sed -i ... bin/ltmain.sh: This sed silences several useless and annoying warnings from libtool.

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 the OpenGL ES 1.x API.

--enable-gles2: This switch enables support for the OpenGL ES 2.x API.

--enable-osmesa: This switch enables building 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, swrast, and swr. You will need to remove r300, r600, radeonsi, and swr from the list if you did not install elfutils and LLVM with the r600/amdgpu and host backends.

--enable-r600-llvm-compiler: Use this switch to enable an experimental R600 LLVM backend for graphics shaders which claims to speed up the driver.
