  34
  35 <h2>1.1 General</h2>
  36 <ul>
  37 <li>lex / yacc - for building the GLSL compiler.
  38 On Linux systems, flex and bison are used.
  39 Versions 2.5.35 and 2.4.1, respectively, (or later) should work.
  40 <br>
  41 <br>
  42 On Windows with MinGW, install flex and bison with:
  43 <pre>mingw-get install msys-flex msys-bison</pre>
  44 </li>
  45 <li>python - Python is needed for building the Gallium components.
  46 Version 2.6.4 or later should work.
  47 <br>
  48 <br>
  49 To build OpenGL ES 1.1 and 2.0 you'll also need
  50 <a href="http://xmlsoft.org/sources/win32/python/libxml2-python-2.7.7.win32-py2.7.exe">libxml2-python</a>.
  51 </li>
  52 </ul>
  53
  54
  55 <h3 id="prereq-dri">1.2 For DRI and hardware acceleration</h3>
  56
  57 <p>
  58 The following are required for DRI-based hardware acceleration with Mesa:
  59 </p>
  60
  61 <ul>
  62 <li><a href="http://xorg.freedesktop.org/releases/individual/proto/">
  63 dri2proto</a> version 2.6 or later
  64 <li><a href="http://dri.freedesktop.org/libdrm/">libDRM</a>
  65 version 2.4.33 or later
  66 <li>Xorg server version 1.5 or later
  67 <li>Linux 2.6.28 or later
  68 </ul>
  69 <p>
  70 If you're using a fedora distro the following command should install all
  71 the needed dependencies:
  72 </p>
  73 <pre>
  74   sudo yum install flex bison imake libtool xorg-x11-proto-devel libdrm-devel \
  75   gcc-c++ xorg-x11-server-devel libXi-devel libXmu-devel libXdamage-devel git \
  76   expat-devel llvm-devel
  77 </pre>

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

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