1Compiling and Installing 2======================== 3 4.. toctree:: 5 :maxdepth: 1 6 :hidden: 7 8 meson 9 101. Prerequisites for building 11----------------------------- 12 131.1 General 14~~~~~~~~~~~ 15 16Build system 17^^^^^^^^^^^^ 18 19- `meson <https://mesonbuild.com>`__ is required when building on \*nix 20 platforms and is supported on windows. 21- `SCons <http://www.scons.org/>`__ is an alternative for building on 22 Windows and Linux. 23- Android Build system when building as native Android component. Meson 24 is used when when building ARC. 25 26Compiler 27^^^^^^^^ 28 29The following compilers are known to work, if you know of others or 30you're willing to maintain support for other compiler get in touch. 31 32- GCC 4.2.0 or later (some parts of Mesa may require later versions) 33- clang - exact minimum requirement is currently unknown. 34- Microsoft Visual Studio 2015 or later is required, for building on 35 Windows. 36 37Third party/extra tools. 38^^^^^^^^^^^^^^^^^^^^^^^^ 39 40- `Python <https://www.python.org/>`__ - Python is required. When 41 building with scons 2.7 is required. When building with meson 3.5 or 42 newer is required. 43- `Python Mako module <http://www.makotemplates.org/>`__ - Python Mako 44 module is required. Version 0.8.0 or later should work. 45- lex / yacc - for building the Mesa IR and GLSL compiler. 46 47 On Linux systems, flex and bison versions 2.5.35 and 2.4.1, 48 respectively, (or later) should work. On Windows with MinGW, install 49 flex and bison with: 50 51 :: 52 53 mingw-get install msys-flex msys-bison 54 55 For MSVC on Windows, install `Win 56 flex-bison <http://winflexbison.sourceforge.net/>`__. 57 58.. note:: 59 60 Some versions can be buggy (eg. flex 2.6.2) so do try others 61 if things fail. 62 631.2 Requirements 64~~~~~~~~~~~~~~~~ 65 66The requirements depends on the features selected at configure stage. 67Check/install the respective -devel package as prompted by the configure 68error message. 69 70Here are some common ways to retrieve most/all of the dependencies based 71on the packaging tool used by your distro. 72 73:: 74 75 zypper source-install --build-deps-only Mesa # openSUSE/SLED/SLES 76 yum-builddep mesa # yum Fedora, OpenSuse(?) 77 dnf builddep mesa # dnf Fedora 78 apt-get build-dep mesa # Debian and derivatives 79 ... # others 80 812. Building with meson 82---------------------- 83 84**Meson >= 0.46.0 is required** 85 86Meson is the latest build system in mesa, it is currently able to build 87for \*nix systems like Linux and BSD, macOS, Haiku, and Windows. 88 89The general approach is: 90 91:: 92 93 meson builddir/ 94 ninja -C builddir/ 95 sudo ninja -C builddir/ install 96 97On windows you can also use the visual studio backend 98 99:: 100 101 meson builddir --backend=vs 102 cd builddir 103 msbuild mesa.sln /m 104 105Please read the :doc:`detailed meson instructions <meson>` for more 106information 107 1083. Building with SCons (Windows/Linux) 109-------------------------------------- 110 111To build Mesa with SCons on Linux or Windows do 112 113:: 114 115 scons 116 117The build output will be placed in 118build/\ *platform*-*machine*-*debug*/..., where *platform* is for 119example linux or windows, *machine* is x86 or x86_64, optionally 120followed by -debug for debug builds. 121 122To build Mesa with SCons for Windows on Linux using the MinGW 123crosscompiler toolchain do 124 125:: 126 127 scons platform=windows toolchain=crossmingw machine=x86 libgl-gdi 128 129This will create: 130 131- build/windows-x86-debug/gallium/targets/libgl-gdi/opengl32.dll — Mesa 132 + Gallium + softpipe (or llvmpipe), binary compatible with Windows's 133 opengl32.dll 134 135Put them all in the same directory to test them. Additional information 136is available in `README.WIN32 <README.WIN32>`__. 137 1384. Building with AOSP (Android) 139------------------------------- 140 141Currently one can build Mesa for Android as part of the AOSP project, 142yet your experience might vary. 143 144In order to achieve that one should update their local manifest to point 145to the upstream repo, set the appropriate BOARD_GPU_DRIVERS and build 146the libGLES_mesa library. 147 148FINISHME: Improve on the instructions add references to Rob H 149repos/Jenkins, Android-x86 and/or other resources. 150 1515. Library Information 152---------------------- 153 154When compilation has finished, look in the top-level ``lib/`` (or 155``lib64/``) directory. You'll see a set of library files similar to 156this: 157 158:: 159 160 lrwxrwxrwx 1 brian users 10 Mar 26 07:53 libGL.so -> libGL.so.1* 161 lrwxrwxrwx 1 brian users 19 Mar 26 07:53 libGL.so.1 -> libGL.so.1.5.060100* 162 -rwxr-xr-x 1 brian users 3375861 Mar 26 07:53 libGL.so.1.5.060100* 163 lrwxrwxrwx 1 brian users 14 Mar 26 07:53 libOSMesa.so -> libOSMesa.so.6* 164 lrwxrwxrwx 1 brian users 23 Mar 26 07:53 libOSMesa.so.6 -> libOSMesa.so.6.1.060100* 165 -rwxr-xr-x 1 brian users 23871 Mar 26 07:53 libOSMesa.so.6.1.060100* 166 167**libGL** is the main OpenGL library (i.e. Mesa), while **libOSMesa** is 168the OSMesa (Off-Screen) interface library. 169 170If you built the DRI hardware drivers, you'll also see the DRI drivers: 171 172:: 173 174 -rwxr-xr-x 1 brian users 16895413 Jul 21 12:11 i915_dri.so 175 -rwxr-xr-x 1 brian users 16895413 Jul 21 12:11 i965_dri.so 176 -rwxr-xr-x 1 brian users 11849858 Jul 21 12:12 r200_dri.so 177 -rwxr-xr-x 1 brian users 11757388 Jul 21 12:12 radeon_dri.so 178 179If you built with Gallium support, look in lib/gallium/ for 180Gallium-based versions of libGL and device drivers. 181 1826. Building OpenGL programs with pkg-config 183------------------------------------------- 184 185Running ``ninja install`` will install package configuration files for 186the pkg-config utility. 187 188When compiling your OpenGL application you can use pkg-config to 189determine the proper compiler and linker flags. 190 191For example, compiling and linking a GLUT application can be done with: 192 193:: 194 195 gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo 196
