Prerequisites for building</h2> <h3>1.1 General</h3> <h4>Build system</h4> <ul> <li><a href="https://mesonbuild.com">meson</a> is required when building on *nix platforms and is supported on windows. <li><a href="http://www.scons.org/">SCons</a> is an alternative for building on Windows and Linux. </li> <li>Android Build system when building as native Android component. Meson is used when when building ARC. </li> </ul> <h4>Compiler</h4> <p> The following compilers are known to work, if you know of others or you're willing to maintain support for other compiler get in touch. </p> <ul> <li>GCC 4.2.0 or later (some parts of Mesa may require later versions) <li>clang - exact minimum requirement is currently unknown. <li>Microsoft Visual Studio 2015 or later is required, for building on Windows. </ul> <h4>Third party/extra tools.</h4> <ul> <li><a href="https://www.python.org/">Python</a> - Python is required. When building with scons 2.7 is required. When building with meson 3.5 or newer is required. </li> <li><a href="http://www.makotemplates.org/">Python Mako module</a> - Python Mako module is required. Version 0.8.0 or later should work. </li> <li>lex / yacc - for building the Mesa IR and GLSL compiler. <p> On Linux systems, flex and bison versions 2.5.35 and 2.4.1, respectively, (or later) should work. On Windows with MinGW, install flex and bison with: <pre>mingw-get install msys-flex msys-bison</pre> For MSVC on Windows, install <a href="http://winflexbison.sourceforge.net/">Win flex-bison</a>. </p> </ul> <p><strong>Note</strong>: Some versions can be buggy (eg. flex 2.6.2) so do try others if things fail.</p> <h3 id="prereq-dri">1.2 Requirements</h3> <p> The requirements depends on the features selected at configure stage. Check/install the respective -devel package as prompted by the configure error message. </p> <p> Here are some common ways to retrieve most/all of the dependencies based on the packaging tool used by your distro. </p> <pre> zypper source-install --build-deps-only Mesa # openSUSE/SLED/SLES yum-builddep mesa # yum Fedora, OpenSuse(?) dnf builddep mesa # dnf Fedora apt-get build-dep mesa # Debian and derivatives ... # others </pre> <h2 id="meson">2. Building with meson</h2> <p><string>Meson &6t;= 0.46.0 is required</string></p> <p> Meson is the latest build system in mesa, it is currently able to build for *nix systems like Linux and BSD, macOS, Haiku, and Windows. </p> <p> The general approach is: </p> <pre> meson builddir/ ninja -C builddir/ sudo ninja -C builddir/ install </pre> <p>On windows you can also use the visual studio backend</p> <pre> meson builddir --backend=vs cd builddir msbuild mesa.sln /m </pre> <p> Please read the <a href="meson.html">detailed meson instructions</a> for more information </p> <h2 id="scons">3. Building with SCons (Windows/Linux)</h2> <p> To build Mesa with SCons on Linux or Windows do </p> <pre> scons </pre> <p> The build output will be placed in build/<i>platform</i>-<i>machine</i>-<i>debug</i>/..., where <i>platform</i> is for example linux or windows, <i>machine</i> is x86 or x86_64, optionally followed by -debug for debug builds. </p> <p> To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do </p> <pre> scons platform=windows toolchain=crossmingw machine=x86 libgl-gdi </pre> <p> This will create: </p> <ul> <li>build/windows-x86-debug/gallium/targets/libgl-gdi/opengl32.dll — Mesa + Gallium + softpipe (or llvmpipe), binary compatible with Windows's opengl32.dll </ul> <p> Put them all in the same directory to test them. Additional information is available in <a href="README.WIN32">README.WIN32</a>. </p> <h2 id="android">4. Building with AOSP (Android)</h2> <p> Currently one can build Mesa for Android as part of the AOSP project, yet your experience might vary. </p> <p> In order to achieve that one should update their local manifest to point to the upstream repo, set the appropriate BOARD_GPU_DRIVERS and build the libGLES_mesa library. </p> <p> FINISHME: Improve on the instructions add references to Rob H repos/Jenkins, Android-x86 and/or other resources. </p> <h2 id="libs">5. Library Information</h2> <p> When compilation has finished, look in the top-level <code>lib/</code> (or <code>lib64/</code>) directory. You'll see a set of library files similar to this: </p> <pre> lrwxrwxrwx 1 brian users 10 Mar 26 07:53 libGL.so -> libGL.so.1* lrwxrwxrwx 1 brian users 19 Mar 26 07:53 libGL.so.1 -> libGL.so.1.5.060100* -rwxr-xr-x 1 brian users 3375861 Mar 26 07:53 libGL.so.1.5.060100* lrwxrwxrwx 1 brian users 14 Mar 26 07:53 libOSMesa.so -> libOSMesa.so.6* lrwxrwxrwx 1 brian users 23 Mar 26 07:53 libOSMesa.so.6 -> libOSMesa.so.6.1.060100* -rwxr-xr-x 1 brian users 23871 Mar 26 07:53 libOSMesa.so.6.1.060100* </pre> <p> <b>libGL</b> is the main OpenGL library (i.e. Mesa), while <b>libOSMesa</b> is the OSMesa (Off-Screen) interface library. </p> <p> If you built the DRI hardware drivers, you'll also see the DRI drivers: </p> <pre> -rwxr-xr-x 1 brian users 16895413 Jul 21 12:11 i915_dri.so -rwxr-xr-x 1 brian users 16895413 Jul 21 12:11 i965_dri.so -rwxr-xr-x 1 brian users 11849858 Jul 21 12:12 r200_dri.so -rwxr-xr-x 1 brian users 11757388 Jul 21 12:12 radeon_dri.so </pre> <p> If you built with Gallium support, look in lib/gallium/ for Gallium-based versions of libGL and device drivers. </p> <h2 id="pkg-config">6. Building OpenGL programs with pkg-config</h2> <p> Running <code>ninja install</code> will install package configuration files for the pkg-config utility. </p> <p> When compiling your OpenGL application you can use pkg-config to determine the proper compiler and linker flags. </p> <p> For example, compiling and linking a GLUT application can be done with: </p> <pre> gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo </pre> </div> </body> </html>
