  28 <h2>1.1 General</h2>
  29 <ul>
  30 <li>lex / yacc - for building the GLSL compiler.
  31 On Linux systems, flex and bison are used.
  32 Versions 2.5.35 and 2.4.1, respectively, (or later) should work.
  33 <br>
  34 <br>
  35 On Windows with MinGW, install flex and bison with:
  36 <pre>mingw-get install msys-flex msys-bison</pre>
  37 </li>
  38 <li>python - Python is needed for building the Gallium components.
  39 Version 2.6.4 or later should work.
  40 <br>
  41 <br>
  42 To build OpenGL ES 1.1 and 2.0 you'll also need
  43 <a href="http://xmlsoft.org/sources/win32/python/libxml2-python-2.7.7.win32-py2.7.exe">libxml2-python</a>.
  44 </li>

  48 <h3 id="prereq-dri">1.2 For DRI and hardware acceleration</h3>
  49
  50 <p>
  51 The following are required for DRI-based hardware acceleration with Mesa:
  52 </p>
  53
  54 <ul>
  55 <li><a href="http://xorg.freedesktop.org/releases/individual/proto/"
  56 target="_parent">dri2proto</a> version 2.6 or later
  57 <li><a href="http://dri.freedesktop.org/libdrm/" target="_parent">libDRM</a>
  58 version 2.4.33 or later
  59 <li>Xorg server version 1.5 or later
  60 <li>Linux 2.6.28 or later
  61 </ul>
  62 <p>
  63 If you're using a fedora distro the following command should install all
  64 the needed dependencies:
  65 </p>
  66 <pre>
  67   sudo yum install flex bison imake libtool xorg-x11-proto-devel libdrm-devel \
  68   gcc-c++ xorg-x11-server-devel libXi-devel libXmu-devel libXdamage-devel git \
  69   expat-devel llvm-devel
  70 </pre>
  71

  73
  74 <h1 id="autoconf">2. Building with autoconf (Linux/Unix/X11)</h1>
  75
  76 <p>
  77 The primary method to build Mesa on Unix systems is with autoconf.
  78 </p>
  79
  80 <p>
  81 The general approach is the standard:
  82 </p>
  83 <pre>
  84   ./configure
  85   make
  86   sudo make install
  87 </pre>
  88 <p>
  89 But please read the <a href="autoconf.html">detailed autoconf instructions</a>
  90 for more details.
  91 </p>
  92
  93
  94
  95 <h1 id="scons">3. Building with SCons (Windows/Linux)</h1>
  96
  97 <p>
  98 To build Mesa with SCons on Linux or Windows do
  99 </p>
 100 <pre>
 101     scons
 102 </pre>
 103 <p>
 104 The build output will be placed in
 105 build/<i>platform</i>-<i>machine</i>-<i>debug</i>/..., where <i>platform</i> is for
 106 example linux or windows, <i>machine</i> is x86 or x86_64, optionally followed
 107 by -debug for debug builds.
 108 </p>
 109
 110 <p>
 111 To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do
 112 </p>
 113 <pre>
 114     scons platform=windows toolchain=crossmingw machine=x86 mesagdi libgl-gdi
 115 </pre>
 116 <p>
 117 This will create:
 118 </p>
 119 <ul>
 120 <li>build/windows-x86-debug/mesa/drivers/windows/gdi/opengl32.dll &mdash; Mesa + swrast, binary compatible with Windows's opengl32.dll
 121 <li>build/windows-x86-debug/gallium/targets/libgl-gdi/opengl32.dll &mdash; Mesa + Gallium + softpipe, binary compatible with Windows's opengl32.dll
 122 </ul>
 123 <p>
 124 Put them all in the same directory to test them.

 143 <h1 id="libs">5. Library Information</h1>
 144
 145 <p>
 146 When compilation has finished, look in the top-level <code>lib/</code>
 147 (or <code>lib64/</code>) directory.
 148 You'll see a set of library files similar to this:
 149 </p>
 150 <pre>
 151 lrwxrwxrwx    1 brian    users          10 Mar 26 07:53 libGL.so -> libGL.so.1*
 152 lrwxrwxrwx    1 brian    users          19 Mar 26 07:53 libGL.so.1 -> libGL.so.1.5.060100*
 153 -rwxr-xr-x    1 brian    users     3375861 Mar 26 07:53 libGL.so.1.5.060100*
 154 lrwxrwxrwx    1 brian    users          14 Mar 26 07:53 libOSMesa.so -> libOSMesa.so.6*
 155 lrwxrwxrwx    1 brian    users          23 Mar 26 07:53 libOSMesa.so.6 -> libOSMesa.so.6.1.060100*
 156 -rwxr-xr-x    1 brian    users       23871 Mar 26 07:53 libOSMesa.so.6.1.060100*
 157 </pre>
 158
 159 <p>
 160 <b>libGL</b> is the main OpenGL library (i.e. Mesa).
 161 <br>
 162 <b>libOSMesa</b> is the OSMesa (Off-Screen) interface library.
 163 </p>
 164
 165 <p>
 166 If you built the DRI hardware drivers, you'll also see the DRI drivers:
 167 </p>
 168 <pre>
 169 -rwxr-xr-x   1 brian users 16895413 Jul 21 12:11 i915_dri.so
 170 -rwxr-xr-x   1 brian users 16895413 Jul 21 12:11 i965_dri.so
 171 -rwxr-xr-x   1 brian users 11849858 Jul 21 12:12 r200_dri.so
 172 -rwxr-xr-x   1 brian users 16050488 Jul 21 12:11 r300_dri.so
 173 -rwxr-xr-x   1 brian users 11757388 Jul 21 12:12 radeon_dri.so
 174 </pre>
 175
 176 <p>
 177 If you built with Gallium support, look in lib/gallium/ for Gallium-based
 178 versions of libGL and device drivers.
 179 </p>
 180
 181
 182 <h1 id="pkg-config">6. Building OpenGL programs with pkg-config</h1>
 183
 184 <p>
 185 Running <code>make install</code> will install package configuration files
 186 for the pkg-config utility.
 187 </p>
 188
 189 <p>
 190 When compiling your OpenGL application you can use pkg-config to determine
 191 the proper compiler and linker flags.
 192 </p>
 193
 194 <p>
 195 For example, compiling and linking a GLUT application can be done with:
 196 </p>
 197 <pre>
 198    gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo
 199 </pre>
