%general-entities; ]> $LastChangedBy$ $Date$ Mesa Mesa is an OpenGL compatible 3D graphics library. Mesa is updated relatively often. You may want to use the latest available &mesa-major-minor;.x mesa version. &lfs84_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &mesa-md5sum; Download size: &mesa-size; Estimated disk space required: &mesa-buildsize; Estimated build time: &mesa-time; Additional Downloads Recommended patch: (installs 2 demo programs for testing Mesa - not needed if you install the mesa-demos package) Mesa Dependencies Required , , and Recommended (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.), (to build VDPAU drivers), (required for Gallium3D, r300, and radeonsi drivers and for the llvmpipe software rasterizer. See for more information), and (required for , GNOME, and recommended for ) Optional , , (not used if Python3 is present), 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) The instructions below assume that LLVM with the r600/amdgpu and host backends are installed. You will need to modify the instructions if you choose not to install it. For an explanation of Gallium3D see . User Notes: 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-&mesa-version;-add_xdemos-1.patch Now, select the drivers you wish to install. The available drivers are i915, nouveau, r300, r600, radeonsi, freedreno, pl111, svga, swrast, swr, tegra, v3d, vc4, virgl, etnaviv, and imx. If the Gallium drivers are not specified, the default is 'r300,r600,svga,swrast'. Modify the command below for any desired drivers. The listed drivers below will cover most modern video cards. For help in selecting drivers see . GLL_DRV="i915,nouveau,radeonsi,svga,swrast" Install Mesa by running the following commands: ./configure CFLAGS='-O2' CXXFLAGS='-O2' LDFLAGS=-lLLVM \ --prefix=$XORG_PREFIX \ --sysconfdir=/etc \ --enable-osmesa \ --enable-xa \ --enable-glx-tls \ --with-platforms="drm,x11,wayland" \ --with-gallium-drivers=$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=$XORG_PREFIX To test the results, issue: make -k check. Now, as the root user: make install If you have built the demo programs, install them by running the following command as the root user: make -C xdemos DEMOS_PREFIX=$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-&mesa-version; && cp -rfv docs/* /usr/share/doc/mesa-&mesa-version; 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 the -g compiler flag so the final libraries are smaller. LDFLAGS=-lLLVM: This environment variable specifies the LLVM libraries that are not automatically included for some of the package components. --enable-osmesa: This switch enables building the libOSMesa library. --enable-xa: This switch enables building the XA X Acceleration API (Required for VMware 3D Driver). --enable-gbm: This switch enables building the Mesa Graphics Buffer Manager library. --enable-glx-tls: This switch enables TLS (Thread Local Storage) support in GLX. --with-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. --enable-sysfs: Use this switch to enable simple PCI identification method, required for building DRI on systems without udev.
