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

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

  77 <H1>2. Building with autoconf (Linux/Unix/X11)</H1>
  78
  79 <p>
  80 The primary method to build Mesa on Unix systems is with autoconf.
  81 </p>
  82
  83 <p>
  84 The general approach is the standard:
  85 <pre>
  86   ./configure
  87   make
  88   sudo make install
  89 </pre>
  90 But please read the <a href="autoconf.html">detailed autoconf instructions</a>
  91 for more details.

  96 <a name="scons">
  97 <H1>3. Building with SCons (Windows/Linux)</H1>
  98
  99 <p>
 100 To build Mesa with SCons on Linux or Windows do
 101 </p>
 102 <pre>
 103     scons
 104 </pre>
 105 <p>
 106 The build output will be placed in
 107 build/<i>platform</i>-<i>machine</i>-<i>debug</i>/..., where <i>platform</i> is for
 108 example linux or windows, <i>machine</i> is x86 or x86_64, optionally followed
 109 by -debug for debug builds.
 110 </p>
 111
 112 <p>
 113 To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do
 114 </p>
 115 <pre>
 116     scons platform=windows toolchain=crossmingw machine=x86 mesagdi libgl-gdi
 117 </pre>
 118 <p>
 119 This will create:
 120 </p>
 121 <ul>
 122 <li>build/windows-x86-debug/mesa/drivers/windows/gdi/opengl32.dll &mdash; Mesa + swrast, binary compatible with Windows's opengl32.dll
 123 <li>build/windows-x86-debug/gallium/targets/libgl-gdi/opengl32.dll &mdash; Mesa + Gallium + softpipe, binary compatible with Windows's opengl32.dll
 124 </ul>
 125 <p>
 126 Put them all in the same directory to test them.

 150 When compilation has finished, look in the top-level <code>lib/</code>
 151 (or <code>lib64/</code>) directory.
 152 You'll see a set of library files similar to this:

 167 <b>libGL</b> is the main OpenGL library (i.e. Mesa).

 169 <b>libGLU</b> is the OpenGL Utility library.

 171 <b>libOSMesa</b> is the OSMesa (Off-Screen) interface library.

 175 If you built the DRI hardware drivers, you'll also see the DRI drivers:

 183 </pre>
 184
 185 <p>
 186 If you built with Gallium support, look in lib/gallium/ for Gallium-based
 187 versions of libGL and device drivers.

 191 <a name="pkg-config">
 192 <H1>6. Building OpenGL programs with pkg-config</H1>
 193
 194 <p>
 195 Running <code>make install</code> will install package configuration files
 196 for the pkg-config utility.
 197 </p>
 198
 199 <p>
 200 When compiling your OpenGL application you can use pkg-config to determine
 201 the proper compiler and linker flags.
 202 </p>
 203
 204 <p>
 205 For example, compiling and linking a GLUT application can be done with:
 206 </p>
 207 <pre>
 208    gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo
 209 </pre>
