31 <H2>1. Unix/X11 Compilation and Installation</H1>
34 <a name="prereq-general">
35 <h3>1.1 General prerequisites for building</h3>
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.
42 <li>python - Python is needed for building the Gallium components.
43 Version 2.6.4 or later should work.
49 <h3>1.2 Prerequisites for DRI and hardware acceleration</h3>
52 The following are required for DRI-based hardware acceleration with Mesa:
56 <li><a href="http://xorg.freedesktop.org/releases/individual/proto/">dri2proto</a> version 1.99.3 or later
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
66 <h3>1.3 Building with Autoconf</h3>
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.
75 <a name="traditional">
76 <h3>1.4 Building with traditional Makefiles</h3>
79 The traditional Mesa build system is based on a collection of pre-defined
80 system configurations.
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>
89 Mesa may be built in several different ways using the predefined configurations:
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.
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:
106 <p>This will produce libGL.so and several other libraries</p>
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.
116 Build Mesa and the DRI hardware drivers by running
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
127 Make sure you have the prerequisite versions of DRM and Xserver mentioned
137 Later, if you want to rebuild for a different configuration run
138 <code>make realclean</code> before rebuilding.
143 <h3>1.5 The libraries</h3>
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:
151 lrwxrwxrwx 1 brian users 10 Mar 26 07:53 libGL.so -> libGL.so.1*
152 lrwxrwxrwx 1 brian users 19 Mar 26 07:53 libGL.so.1 -> libGL.so.1.5.060100*
153 -rwxr-xr-x 1 brian users 3375861 Mar 26 07:53 libGL.so.1.5.060100*
154 lrwxrwxrwx 1 brian users 11 Mar 26 07:53 libGLU.so -> libGLU.so.1*
155 lrwxrwxrwx 1 brian users 20 Mar 26 07:53 libGLU.so.1 -> libGLU.so.1.3.060100*
156 -rwxr-xr-x 1 brian users 549269 Mar 26 07:53 libGLU.so.1.3.060100*
157 lrwxrwxrwx 1 brian users 12 Mar 26 07:53 libglut.so -> libglut.so.3*
158 lrwxrwxrwx 1 brian users 16 Mar 26 07:53 libglut.so.3 -> libglut.so.3.7.1*
159 -rwxr-xr-x 1 brian users 597754 Mar 26 07:53 libglut.so.3.7.1*
160 lrwxrwxrwx 1 brian users 14 Mar 26 07:53 libOSMesa.so -> libOSMesa.so.6*
161 lrwxrwxrwx 1 brian users 23 Mar 26 07:53 libOSMesa.so.6 -> libOSMesa.so.6.1.060100*
162 -rwxr-xr-x 1 brian users 23871 Mar 26 07:53 libOSMesa.so.6.1.060100*
166 <b>libGL</b> is the main OpenGL library (i.e. Mesa).
168 <b>libGLU</b> is the OpenGL Utility library.
170 <b>libglut</b> is the GLUT library.
172 <b>libOSMesa</b> is the OSMesa (Off-Screen) interface library.
176 If you built the DRI hardware drivers, you'll also see the DRI drivers:
179 -rwxr-xr-x 1 brian users 16895413 Jul 21 12:11 i915_dri.so
180 -rwxr-xr-x 1 brian users 11849858 Jul 21 12:12 r200_dri.so
181 -rwxr-xr-x 1 brian users 16050488 Jul 21 12:11 r300_dri.so
182 -rwxr-xr-x 1 brian users 11757388 Jul 21 12:12 radeon_dri.so
186 If you built with Gallium support, look in lib/gallium/ for Gallium-based
187 versions of libGL and device drivers.
193 <H3>1.6 Installing the header and library files</H3>
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>.
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>.
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>.
219 <b>DESTDIR</b> may also be used to install the contents to a temporary
221 This can be useful for package management.
222 For example: <code>make install DESTDIR=/somepath/</code>
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.
233 <a name="pkg-config">
234 <H3>1.7 Building OpenGL programs with pkg-config</H3>
237 Running <code>make install</code> will install package configuration files
238 for the pkg-config utility.
242 When compiling your OpenGL application you can use pkg-config to determine
243 the proper compiler and linker flags.
247 For example, compiling and linking a GLUT application can be done with:
250 gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo
256 <H2>2. Windows Compilation and Installation</H1>
259 Please see the <a href="#scons">instructions on building with SCons</a>.
265 <H2>3. Building with SCons</H1>
268 To build Mesa with SCons on Linux or Windows do
274 The build output will be placed in
275 build/<i>platform</i>-<i>machine</i>-<i>debug</i>/..., where <i>platform</i> is for
276 example linux or windows, <i>machine</i> is x86 or x86_64, optionally followed
277 by -debug for debug builds.
281 To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do
284 scons platform=windows toolchain=crossmingw machine=x86 mesagdi libgl-gdi
290 <li>build/windows-x86-debug/mesa/drivers/windows/gdi/opengl32.dll — Mesa + swrast, binary compatible with Windows's opengl32.dll
291 <li>build/windows-x86-debug/gallium/targets/libgl-gdi/opengl32.dll — Mesa + Gallium + softpipe, binary compatible with Windows's opengl32.dll
294 Put them all in the same directory to test them.
