35<h3>1.1 General prerequisites for building</h3>
36
37<ul>
38<li>lex / yacc - for building the GLSL compiler.
39On Linux systems, flex and bison are used.
40Versions 2.5.35 and 2.4.1, respectively, (or later) should work.
41</li>
42<li>python - Python is needed for building the Gallium components.
43Version 2.6.4 or later should work.

49<h3>1.2 Prerequisites for DRI and hardware acceleration</h3>
50
51<p>
52The 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>
59version 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>
69Mesa may be <a href="autoconf.html">built using autoconf</a>.
70This should work well on most GNU-based systems.
71If 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>
79The traditional Mesa build system is based on a collection of pre-defined
80system configurations.
81</p>
82<p>
83To see the list of configurations, just type <code>make</code>.
84Then choose a configuration from the list and type <code>make</code>
85<em>configname</em>.
86</p>
87
88<p>
89Mesa 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
93a software renderer using Xlib to do all rendering.
94The libGL.so library will be a self-contained rendering library that will
95allow you to run OpenGL/GLX applications on any X server (regardless of
96whether it supports the GLX X server extension).
97You will <em>not</em> be able to use hardware 3D acceleration.
98<p>
99To compile stand-alone Mesa type <code>make</code> in the top-level directory.
100You'll see a list of supported system configurations.
101Choose 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
110accelerated OpenGL rendering (for ATI, Intel, Matrox, etc) will be built.
111The libGL.so library will support the GLX extension and will load/use
112the DRI hardware drivers.
113
114
115<p>
116Build Mesa and the DRI hardware drivers by running
117</p>
118<pre>
119   make linux-dri
120</pre>
121<p>
122There are also <code>linux-dri-x86</code>, <code>linux-dri-x86-64</code>, 
123and <code>linux-ppc</code> configurations which are optimized for those
124architectures.
125</p>
126<p>
127Make sure you have the prerequisite versions of DRM and Xserver mentioned
128above.
129</p>
130
131</li>
132
133</ul>
134
135
136<p>
137Later, 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>
146When compilation has finished, look in the top-level <code>lib/</code>
147(or <code>lib64/</code>) directory.
148You'll see a set of library files similar to this:

166<b>libGL</b> is the main OpenGL library (i.e. Mesa).
167<br>
168<b>libGLU</b> is the OpenGL Utility library.
169<br>
170<b>libglut</b> is the GLUT library.
171<br>
172<b>libOSMesa</b> is the OSMesa (Off-Screen) interface library.
173</p>
174
175<p>
176If you built the DRI hardware drivers, you'll also see the DRI drivers:

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

192<a name="install">
193<H3>1.6 Installing the header and library files</H3>
194
195<p>
196The standard location for the OpenGL header files on Unix-type systems is
197in <code>/usr/include/GL/</code>.
198The standard location for the libraries is <code>/usr/lib/</code>.
199For more information see, the
200<a href="http://oss.sgi.com/projects/ogl-sample/ABI/" target="_parent">
201Linux/OpenGL ABI specification</a>.
202</p>
203
204<p>
205If you'd like Mesa to co-exist with another implementation of OpenGL that's
206already 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>
211To install Mesa's headers and libraries, run <code>make install</code>.
212But first, check the Mesa/configs/default file and examine the values
213of the <b>INSTALL_DIR</b> and <b>DRI_DRIVER_INSTALL_DIR</b> variables.
214Change them if needed, then run <code>make install</code>.
215</p>
216
217<p>
218The variable
219<b>DESTDIR</b> may also be used to install the contents to a temporary
220staging directory.
221This can be useful for package management.
222For example: <code>make install DESTDIR=/somepath/</code>
223</p>
224
225<p>
226Note: at runtime you can use the LD_LIBRARY_PATH environment variable
227(on Linux at least) to switch
228between the Mesa libraries and other vendor's libraries whenever you want.
229This 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>
237Running <code>make install</code> will install package configuration files
238for the pkg-config utility.
239</p>
240
241<p>
242When compiling your OpenGL application you can use pkg-config to determine
243the proper compiler and linker flags.
244</p>
245
246<p>
247For 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
