  35
  36 <h3>1.1 General</h3>
  37
  38 <h4>Build system</h4>
  39
  40 <ul>
  41 <li><a href="https://mesonbuild.com">meson</a> is required when building on *nix platforms.
  42 <li>Autoconf was removed in 19.1.0, use meson instead
  43 <li><a href="http://www.scons.org/">SCons</a> is required for building on
  44 Windows and optional for Linux (it's an alternative to meson.)
  45 </li>
  46 <li>Android Build system when building as native Android component. Meson
  47 is used when when building ARC.
  48 </li>
  49 </ul>
  50
  51 <h4>Compiler</h4>
  52 <p>
  53 The following compilers are known to work, if you know of others or you're
  54 willing to maintain support for other compiler get in touch.
  55 </p>
  56
  57 <ul>
  58 <li>GCC 4.2.0 or later (some parts of Mesa may require later versions)
  59 <li>clang - exact minimum requirement is currently unknown.
  60 <li>Microsoft Visual Studio 2015 or later is required, for building on Windows.
  61 </ul>
  62
  63
  64 <h4>Third party/extra tools.</h4>
  65
  66 <ul>
  67 <li><a href="https://www.python.org/">Python</a> - Python is required.
  68 When building with scons 2.7 is required.
  69 When building with meson 3.5 or newer is required.
  70 </li>
  71 <li><a href="http://www.makotemplates.org/">Python Mako module</a> -
  72 Python Mako module is required. Version 0.8.0 or later should work.
  73 </li>
  74 <li>lex / yacc - for building the Mesa IR and GLSL compiler.
  75 <p>
  76 On Linux systems, flex and bison versions 2.5.35 and 2.4.1, respectively,
  77 (or later) should work.
  78 On Windows with MinGW, install flex and bison with:
  79 <pre>mingw-get install msys-flex msys-bison</pre>
  80 For MSVC on Windows, install
  81 <a href="http://winflexbison.sourceforge.net/">Win flex-bison</a>.
  82 </p>
  83 </ul>
  84 <p><strong>Note</strong>: Some versions can be buggy (eg. flex 2.6.2) so do try others if things fail.</p>
  85
  86
  87 <h3 id="prereq-dri">1.2 Requirements</h3>
  88
  89 <p>
  90 The requirements depends on the features selected at configure stage.
  91 Check/install the respective -devel package as prompted by the configure error
  92 message.
  93 </p>
  94
  95 <p>
  96 Here are some common ways to retrieve most/all of the dependencies based on
  97 the packaging tool used by your distro.
  98 </p>
  99
 100 <pre>
 101   zypper source-install --build-deps-only Mesa # openSUSE/SLED/SLES
 102   yum-builddep mesa # yum Fedora, OpenSuse(?)
 103   dnf builddep mesa # dnf Fedora
 104   apt-get build-dep mesa # Debian and derivatives
 105   ... # others
 106 </pre>
 107
 108 <h2 id="meson">2. Building with meson</h2>
 109
 110 <p><string>Meson &6t;= 0.46.0 is required</string></p>
 111
 112 <p>
 113 Meson is the latest build system in mesa, it is currently able to build for
 114 *nix systems like Linux and BSD, macOS, Haiku, and will be able to build for
 115 windows as well.
 116 </p>
 117
 118 <p>
 119 The general approach is:
 120 </p>
 121 <pre>
 122   meson builddir/
 123   ninja -C builddir/
 124   sudo ninja -C builddir/ install
 125 </pre>
 126 <p>
 127 Please read the <a href="meson.html">detailed meson instructions</a>
 128 for more information
 129 </p>
 130
 131 <h2 id="autoconf">3. Building with autoconf (Linux/Unix/X11)</h2>
 132
 133 <p>
 134   Autoconf support was removed in Mesa 19.1.0. Please use meson instead.
 135 </p>
 136
 137
 138
 139 <h2 id="scons">4. Building with SCons (Windows/Linux)</h2>
 140
 141 <p>
 142 To build Mesa with SCons on Linux or Windows do
 143 </p>
 144 <pre>
 145     scons
 146 </pre>
 147 <p>
 148 The build output will be placed in
 149 build/<i>platform</i>-<i>machine</i>-<i>debug</i>/..., where <i>platform</i> is for
 150 example linux or windows, <i>machine</i> is x86 or x86_64, optionally followed
 151 by -debug for debug builds.
 152 </p>
 153
 154 <p>
 155 To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do
 156 </p>
 157 <pre>
 158     scons platform=windows toolchain=crossmingw machine=x86 libgl-gdi
 159 </pre>
 160 <p>
 161 This will create:
 162 </p>
 163 <ul>
 164 <li>build/windows-x86-debug/gallium/targets/libgl-gdi/opengl32.dll &mdash; Mesa + Gallium + softpipe (or llvmpipe), binary compatible with Windows's opengl32.dll
 165 </ul>
 166 <p>
 167 Put them all in the same directory to test them.
 168
 169 Additional information is available in <a href="README.WIN32">README.WIN32</a>.
 170
 171 </p>
 172
 173
 174
 175 <h2 id="android">5. Building with AOSP (Android)</h2>
 176
 177 <p>
 178 Currently one can build Mesa for Android as part of the AOSP project, yet
 179 your experience might vary.
 180 </p>
 181
 182 <p>
 183 In order to achieve that one should update their local manifest to point to the
 184 upstream repo, set the appropriate BOARD_GPU_DRIVERS and build the
 185 libGLES_mesa library.
 186 </p>
 187
 188 <p>
 189 FINISHME: Improve on the instructions add references to Rob H repos/Jenkins,
 190 Android-x86 and/or other resources.
 191 </p>
 192
 193
 194 <h2 id="libs">6. Library Information</h2>
 195
 196 <p>
 197 When compilation has finished, look in the top-level <code>lib/</code>
 198 (or <code>lib64/</code>) directory.
 199 You'll see a set of library files similar to this:
 200 </p>
 201 <pre>
 202 lrwxrwxrwx    1 brian    users          10 Mar 26 07:53 libGL.so -&gt; libGL.so.1*
 203 lrwxrwxrwx    1 brian    users          19 Mar 26 07:53 libGL.so.1 -&gt; libGL.so.1.5.060100*
 204 -rwxr-xr-x    1 brian    users     3375861 Mar 26 07:53 libGL.so.1.5.060100*
 205 lrwxrwxrwx    1 brian    users          14 Mar 26 07:53 libOSMesa.so -&gt; libOSMesa.so.6*
 206 lrwxrwxrwx    1 brian    users          23 Mar 26 07:53 libOSMesa.so.6 -&gt; libOSMesa.so.6.1.060100*
 207 -rwxr-xr-x    1 brian    users       23871 Mar 26 07:53 libOSMesa.so.6.1.060100*
 208 </pre>
 209
 210 <p>
 211 <b>libGL</b> is the main OpenGL library (i.e. Mesa), while <b>libOSMesa</b>
 212 is the OSMesa (Off-Screen) interface library.
 213 </p>
 214
 215 <p>
 216 If you built the DRI hardware drivers, you'll also see the DRI drivers:
 217 </p>
 218 <pre>
 219 -rwxr-xr-x   1 brian users 16895413 Jul 21 12:11 i915_dri.so
 220 -rwxr-xr-x   1 brian users 16895413 Jul 21 12:11 i965_dri.so
 221 -rwxr-xr-x   1 brian users 11849858 Jul 21 12:12 r200_dri.so
 222 -rwxr-xr-x   1 brian users 11757388 Jul 21 12:12 radeon_dri.so
 223 </pre>
 224
 225 <p>
 226 If you built with Gallium support, look in lib/gallium/ for Gallium-based
 227 versions of libGL and device drivers.
 228 </p>
 229
 230
 231 <h2 id="pkg-config">7. Building OpenGL programs with pkg-config</h2>
 232
 233 <p>
 234 Running <code>ninja install</code> will install package configuration files
 235 for the pkg-config utility.
 236 </p>
 237
 238 <p>
 239 When compiling your OpenGL application you can use pkg-config to determine
 240 the proper compiler and linker flags.
 241 </p>
 242
 243 <p>
 244 For example, compiling and linking a GLUT application can be done with:
 245 </p>
 246 <pre>
 247    gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo
 248 </pre>
