| <h2 id="prereq-general">1. 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: |
| </p> |
| <pre>mingw-get install msys-flex msys-bison</pre> |
| <p> |
| 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><strong>Meson >= 0.46.0 is required</strong></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> |
