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

  57 <h3>1.2 Prerequisites for DRI and hardware acceleration</h3>
  58
  59 <p>
  60 The following are required for DRI-based hardware acceleration with Mesa:
  61 </p>
  62
  63 <ul>
  64 <li><a href="http://xorg.freedesktop.org/releases/individual/proto/">dri2proto</a> version 1.99.3 or later
  65 <li>Linux 2.6.28
  66 <li><a href="http://dri.freedesktop.org/libdrm/" target="_parent">libDRM</a>
  67 version 2.4.15 or later
  68 <li>Xorg server version 1.5 or later
  69 </ul>
  70 </p>
  71 <p>
  72 If you're using a fedora distro the following command should install all
  73 the needed dependencies:
  74 <pre>
  75   sudo yum install flex bison imake libtool xorg-x11-proto-devel libdrm-devel \
  76   gcc-c++ xorg-x11-server-devel libXi-devel libXmu-devel libXdamage-devel git \
  77   expat-devel llvm-devel

  79

  81 <a name="autoconf">
  82 <h3>1.3 Building with Autoconf</h3>
  83
  84 <p>
  85 Mesa may be <a href="autoconf.html">built using autoconf</a>.
  86 This should work well on most GNU-based systems.
  87 If that fails the traditional Mesa build system is available.
  88
  89
  90
  91 <a name="traditional">
  92 <h3>1.4 Building with traditional Makefiles</h3>
  93
  94 <p>
  95 The traditional Mesa build system is based on a collection of pre-defined
  96 system configurations.
  97 </p>
  98 <p>
  99 To see the list of configurations, just type <code>make</code>.
 100 Then choose a configuration from the list and type <code>make</code>
 101 <em>configname</em>.
 102 </p>
 103
 104 <p>
 105 Mesa may be built in several different ways using the predefined configurations:
 106 </p>
 107 <ul>
 108 <li><b><em>Stand-alone/Xlib mode</em></b> - Mesa will be compiled as
 109 a software renderer using Xlib to do all rendering.
 110 The libGL.so library will be a self-contained rendering library that will
 111 allow you to run OpenGL/GLX applications on any X server (regardless of
 112 whether it supports the GLX X server extension).
 113 You will <em>not</em> be able to use hardware 3D acceleration.
 114 <p>
 115 To compile stand-alone Mesa type <code>make</code> in the top-level directory.
 116 You'll see a list of supported system configurations.
 117 Choose one from the list (such as linux-x86), and type:
 118 </p>
 119 <pre>
 120     make linux-x86
 121 </pre>
 122 <p>This will produce libGL.so and several other libraries</p>
 123 </li>
 124
 125 <li><b><em>DRI/accelerated</em></b> - The DRI hardware drivers for
 126 accelerated OpenGL rendering (for ATI, Intel, Matrox, etc) will be built.
 127 The libGL.so library will support the GLX extension and will load/use
 128 the DRI hardware drivers.
 129
 130
 131 <p>
 132 Build Mesa and the DRI hardware drivers by running
 133 </p>
 134 <pre>
 135    make linux-dri
 136 </pre>
 137 <p>
 138 There are also <code>linux-dri-x86</code>, <code>linux-dri-x86-64</code>,
 139 and <code>linux-ppc</code> configurations which are optimized for those
 140 architectures.
 141 </p>
 142 <p>
 143 Make sure you have the prerequisite versions of DRM and Xserver mentioned
 144 above.
 145 </p>
 146
 147 </li>
 148
 149 </ul>
 150
 151
 152 <p>
 153 Later, if you want to rebuild for a different configuration run
 154 <code>make realclean</code> before rebuilding.
 155 </p>
 156
 157
 158 <a name="libs">
 159 <h3>1.5 The libraries</h3>
 160
 161 <p>
 162 When compilation has finished, look in the top-level <code>lib/</code>
 163 (or <code>lib64/</code>) directory.
 164 You'll see a set of library files similar to this:
 165 </p>

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

 199 </pre>
 200
 201 <p>
 202 If you built with Gallium support, look in lib/gallium/ for Gallium-based
 203 versions of libGL and device drivers.

 208 <a name="install">
 209 <H3>1.6 Installing the header and library files</H3>
 210
 211 <p>
 212 The standard location for the OpenGL header files on Unix-type systems is
 213 in <code>/usr/include/GL/</code>.
 214 The standard location for the libraries is <code>/usr/lib/</code>.
 215 For more information see, the
 216 <a href="http://oss.sgi.com/projects/ogl-sample/ABI/" target="_parent">
 217 Linux/OpenGL ABI specification</a>.
 218 </p>
 219
 220 <p>
 221 If you'd like Mesa to co-exist with another implementation of OpenGL that's
 222 already installed, you'll have to choose different directories, like
 223 <code>/usr/local/include/GL/</code> and <code>/usr/local/lib/</code>.
 224 </p>
 225
 226 <p>
 227 To install Mesa's headers and libraries, run <code>make install</code>.
 228 But first, check the Mesa/configs/default file and examine the values
 229 of the <b>INSTALL_DIR</b> and <b>DRI_DRIVER_INSTALL_DIR</b> variables.
 230 Change them if needed, then run <code>make install</code>.
 231 </p>
 232
 233 <p>
 234 The variable
 235 <b>DESTDIR</b> may also be used to install the contents to a temporary
 236 staging directory.
 237 This can be useful for package management.
 238 For example: <code>make install DESTDIR=/somepath/</code>
 239 </p>
 240
 241 <p>
 242 Note: at runtime you can use the LD_LIBRARY_PATH environment variable
 243 (on Linux at least) to switch
 244 between the Mesa libraries and other vendor's libraries whenever you want.
 245 This is a handy way to compare multiple OpenGL implementations.
 246 </p>

 248
 249 <a name="pkg-config">
 250 <H3>1.7 Building OpenGL programs with pkg-config</H3>
 251
 252 <p>
 253 Running <code>make install</code> will install package configuration files
 254 for the pkg-config utility.
 255 </p>
 256
 257 <p>
 258 When compiling your OpenGL application you can use pkg-config to determine
 259 the proper compiler and linker flags.
 260 </p>
 261
 262 <p>
 263 For example, compiling and linking a GLUT application can be done with:
 264 </p>
 265 <pre>
 266    gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo
 267 </pre>
