Unix/X11 Compilation and Installation</H1> 23 24<h3>1.1 Compilation</h3> 25 26<p> 27Mesa may be compiled in several different ways: 28</p> 29<ul> 30<li><b><em>Stand-alone/Xlib mode</em></b> - Mesa will be compiled as 31a software renderer using Xlib to do all rendering. 32The libGL.so library will be a self-contained rendering library that will 33allow you to run OpenGL/GLX applications on any X server (regardless of 34whether it supports the GLX X server extension). 35You will <em>not</em> be able to use hardware 3D acceleration. 36<p> 37To compile stand-alone Mesa type <b>make</b> in the top-level directory. 38You'll see a list of supported system configurations. 39Choose one from the list (such as linux-x86), and type: 40</p> 41<pre> 42 make linux-x86 43</pre> 44<p>This will produce libGL.so and several other libraries</p> 45</li> 46 47<li><b><em>DRI/accelerated</em></b> - The DRI hardware drivers for 48accelerated OpenGL rendering (for ATI, Intel, Matrox, etc) will be built. 49The libGL.so library will support the GLX extension and will load/use 50the DRI hardware drivers. 51 52<p> 53<b>Prerequisites:</b> 54</p> 55 56<ol> 57 58<li> 59<p> 60For Mesa 7.0.2 <a href="http://dri.freedesktop.org/libdrm/"> 61DRM version 2.3</a> is required. 62</p> 63<p> 64To check if you already have it, run: 65<br> 66<code>pkg-config --modversion libdrm</code> 67</p> 68<p> 69You can download and install a <a href="http://dri.freedesktop.org/libdrm/"> 70tarball release</a> or get the code from git with: 71<br> 72<code>git clone git://anongit.freedesktop.org/git/mesa/drm</code> 73<br> 74Then revert to the drm-2.3.0 tag with: 75<br> 76<code>git-reset --hard drm-2.3.0</code> 77</p> 78</li> 79 80<li> 81Relatively recent 82<a href="http://freedesktop.org/wiki/Software_2fXserver" target="_parent"> 83X.org</a> release. 84Mesa depends on a number of X header and library files. 85</li> 86 87</ol> 88 89 90<p> 91Build Mesa and the DRI hardware drivers by running 92</p> 93<pre> 94 make linux-dri 95</pre> 96<p> 97There are also <code>linux-dri-x86</code>, <code>linux-dri-x86-64</code>, 98and <code>linux-ppc</code> configurations which are optimized for those 99architectures. 100</p> 101 102</li> 103</ul> 104 105 106<p> 107Later, if you want to rebuild for a different configuration run 108<code>make realclean</code> before rebuilding. 109</p> 110 111 112<h3>1.2 The libraries</h3> 113 114<p> 115When compilation has finished, look in the top-level <code>lib/</code> 116(or <code>lib64/</code>) directory. 117You'll see a set of library files similar to this: 118</p> 119<pre> 120lrwxrwxrwx 1 brian users 10 Mar 26 07:53 libGL.so -> libGL.so.1* 121lrwxrwxrwx 1 brian users 19 Mar 26 07:53 libGL.so.1 -> libGL.so.1.5.060100* 122-rwxr-xr-x 1 brian users 3375861 Mar 26 07:53 libGL.so.1.5.060100* 123lrwxrwxrwx 1 brian users 11 Mar 26 07:53 libGLU.so -> libGLU.so.1* 124lrwxrwxrwx 1 brian users 20 Mar 26 07:53 libGLU.so.1 -> libGLU.so.1.3.060100* 125-rwxr-xr-x 1 brian users 549269 Mar 26 07:53 libGLU.so.1.3.060100* 126lrwxrwxrwx 1 brian users 12 Mar 26 07:53 libglut.so -> libglut.so.3* 127lrwxrwxrwx 1 brian users 16 Mar 26 07:53 libglut.so.3 -> libglut.so.3.7.1* 128-rwxr-xr-x 1 brian users 597754 Mar 26 07:53 libglut.so.3.7.1* 129lrwxrwxrwx 1 brian users 11 Mar 26 08:04 libGLw.so -> libGLw.so.1* 130lrwxrwxrwx 1 brian users 15 Mar 26 08:04 libGLw.so.1 -> libGLw.so.1.0.0* 131-rwxr-xr-x 1 brian users 20750 Mar 26 08:04 libGLw.so.1.0.0* 132lrwxrwxrwx 1 brian users 14 Mar 26 07:53 libOSMesa.so -> libOSMesa.so.6* 133lrwxrwxrwx 1 brian users 23 Mar 26 07:53 libOSMesa.so.6 -> libOSMesa.so.6.1.060100* 134-rwxr-xr-x 1 brian users 23871 Mar 26 07:53 libOSMesa.so.6.1.060100* 135</pre> 136 137<p> 138<b>libGL</b> is the main OpenGL library (i.e. Mesa). 139<br> 140<b>libGLU</b> is the OpenGL Utility library. 141<br> 142<b>libglut</b> is the GLUT library. 143<br> 144<b>libGLw</b> is the Xt/Motif OpenGL drawing area widget library. 145<br> 146<b>libOSMesa</b> is the OSMesa (Off-Screen) interface library. 147</p> 148 149<p> 150If you built the DRI hardware drivers, you'll also see the DRI drivers: 151</p> 152<pre> 153-rwxr-xr-x 1 brian users 15607851 Jul 21 12:11 ffb_dri.so* 154-rwxr-xr-x 1 brian users 15148747 Jul 21 12:11 i810_dri.so* 155-rwxr-xr-x 1 brian users 14497814 Jul 21 12:11 i830_dri.so* 156-rwxr-xr-x 1 brian users 16895413 Jul 21 12:11 i915_dri.so* 157-rwxr-xr-x 1 brian users 11320803 Jul 21 12:11 mach64_dri.so 158-rwxr-xr-x 1 brian users 11418014 Jul 21 12:12 mga_dri.so 159-rwxr-xr-x 1 brian users 11064426 Jul 21 12:12 r128_dri.so 160-rwxr-xr-x 1 brian users 11849858 Jul 21 12:12 r200_dri.so 161-rwxr-xr-x 1 brian users 16050488 Jul 21 12:11 r300_dri.so* 162-rwxr-xr-x 1 brian users 11757388 Jul 21 12:12 radeon_dri.so 163-rwxr-xr-x 1 brian users 11232304 Jul 21 12:13 s3v_dri.so 164-rwxr-xr-x 1 brian users 11062970 Jul 21 12:13 savage_dri.so 165-rwxr-xr-x 1 brian users 11214212 Jul 21 12:13 sis_dri.so 166-rwxr-xr-x 1 brian users 11368736 Jul 21 12:13 tdfx_dri.so 167-rwxr-xr-x 1 brian users 10598868 Jul 21 12:13 trident_dri.so 168-rwxr-xr-x 1 brian users 10997120 Jul 21 12:13 unichrome_dri.so 169</pre> 170 171 172<h3>1.3 Running the demos</h3> 173 174<p> 175If you downloaded/unpacked the MesaDemos-x.y.z.tar.gz archive or 176obtained Mesa from CVS, the <b>progs/</b> directory will contain a 177bunch of demonstration programs. 178</p> 179 180<p> 181Before running a demo, you may have to set an environment variable 182(such as <b>LD_LIBRARY_PATH</b> on Linux) to indicate where the 183libraries are located.
