  49 <h3>1.2 Prerequisites for DRI and hardware acceleration</h3>
  50
  51 <p>
  52 The following are required for DRI-based hardware acceleration with Mesa:
  53 </p>
  54
  55 <ul>
  56 <li><a href="http://xorg.freedesktop.org/releases/individual/proto/">dri2proto</a> version 1.99.3 or later
  57 <li>Linux 2.6.28
  58 <li><a href="http://dri.freedesktop.org/libdrm/" target="_parent">libDRM</a>
  59 version 2.4.15 or later
  60 <li>Xorg server version 1.5 or later
  61 </ul>
  62 </p>
  63
  64
  65 <a name="autoconf">
  66 <h3>1.3 Building with Autoconf</h3>
  67
  68 <p>
  69 Mesa may be <a href="autoconf.html">built using autoconf</a>.
  70 This should work well on most GNU-based systems.
  71 If that fails the traditional Mesa build system is available.
  72
  73
  74
  75 <a name="traditional">
  76 <h3>1.4 Building with traditional Makefiles</h3>
  77
  78 <p>
  79 The traditional Mesa build system is based on a collection of pre-defined
  80 system configurations.
  81 </p>
  82 <p>
  83 To see the list of configurations, just type <code>make</code>.
  84 Then choose a configuration from the list and type <code>make</code>
  85 <em>configname</em>.
  86 </p>
  87
  88 <p>
  89 Mesa may be built in several different ways using the predefined configurations:
  90 </p>
  91 <ul>
  92 <li><b><em>Stand-alone/Xlib mode</em></b> - Mesa will be compiled as
  93 a software renderer using Xlib to do all rendering.
  94 The libGL.so library will be a self-contained rendering library that will
  95 allow you to run OpenGL/GLX applications on any X server (regardless of
  96 whether it supports the GLX X server extension).
  97 You will <em>not</em> be able to use hardware 3D acceleration.
  98 <p>
  99 To compile stand-alone Mesa type <code>make</code> in the top-level directory.
 100 You'll see a list of supported system configurations.
 101 Choose one from the list (such as linux-x86), and type:
 102 </p>
 103 <pre>
 104     make linux-x86
 105 </pre>
 106 <p>This will produce libGL.so and several other libraries</p>
 107 </li>
 108
 109 <li><b><em>DRI/accelerated</em></b> - The DRI hardware drivers for
 110 accelerated OpenGL rendering (for ATI, Intel, Matrox, etc) will be built.
 111 The libGL.so library will support the GLX extension and will load/use
 112 the DRI hardware drivers.
 113
 114
 115 <p>
 116 Build Mesa and the DRI hardware drivers by running
 117 </p>
 118 <pre>
 119    make linux-dri
 120 </pre>
 121 <p>
 122 There are also <code>linux-dri-x86</code>, <code>linux-dri-x86-64</code>,
 123 and <code>linux-ppc</code> configurations which are optimized for those
 124 architectures.
 125 </p>
 126 <p>
 127 Make sure you have the prerequisite versions of DRM and Xserver mentioned
 128 above.
 129 </p>
 130
 131 </li>
 132
 133 </ul>
 134
 135
 136 <p>
 137 Later, if you want to rebuild for a different configuration run
 138 <code>make realclean</code> before rebuilding.
 139 </p>
 140
 141
 142 <a name="libs">
 143 <h3>1.5 The libraries</h3>
 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:

 184

 186 If you built with Gallium support, look in lib/gallium/ for Gallium-based
 187 versions of libGL and device drivers.

 192 <a name="install">
 193 <H3>1.6 Installing the header and library files</H3>
 194
 195 <p>
 196 The standard location for the OpenGL header files on Unix-type systems is
 197 in <code>/usr/include/GL/</code>.
 198 The standard location for the libraries is <code>/usr/lib/</code>.
 199 For more information see, the
 200 <a href="http://oss.sgi.com/projects/ogl-sample/ABI/" target="_parent">
 201 Linux/OpenGL ABI specification</a>.
 202 </p>
 203
 204 <p>
 205 If you'd like Mesa to co-exist with another implementation of OpenGL that's
 206 already installed, you'll have to choose different directories, like
 207 <code>/usr/local/include/GL/</code> and <code>/usr/local/lib/</code>.
 208 </p>
 209
 210 <p>
 211 To install Mesa's headers and libraries, run <code>make install</code>.
 212 But first, check the Mesa/configs/default file and examine the values
 213 of the <b>INSTALL_DIR</b> and <b>DRI_DRIVER_INSTALL_DIR</b> variables.
 214 Change them if needed, then run <code>make install</code>.
 215 </p>
 216
 217 <p>
 218 The variable
 219 <b>DESTDIR</b> may also be used to install the contents to a temporary
 220 staging directory.
 221 This can be useful for package management.
 222 For example: <code>make install DESTDIR=/somepath/</code>
 223 </p>
 224
 225 <p>
 226 Note: at runtime you can use the LD_LIBRARY_PATH environment variable
 227 (on Linux at least) to switch
 228 between the Mesa libraries and other vendor's libraries whenever you want.
 229 This is a handy way to compare multiple OpenGL implementations.
 230 </p>

 232
 233 <a name="pkg-config">
 234 <H3>1.7 Building OpenGL programs with pkg-config</H3>
 235
 236 <p>
 237 Running <code>make install</code> will install package configuration files
 238 for the pkg-config utility.
 239 </p>
 240
 241 <p>
 242 When compiling your OpenGL application you can use pkg-config to determine
 243 the proper compiler and linker flags.
 244 </p>
 245
 246 <p>
 247 For example, compiling and linking a GLUT application can be done with:
 248 </p>
 249 <pre>
 250    gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo
