The DRI hardware drivers (for ATI, +Intel, Matrox, etc) are built. +libGL.so implements the GLX extension and dynamically loads the DRI drivers. +<p> +To build the DRI drivers you'll first need to have the DRM (Direct +Rendering Manager) kernel drivers and header files. +They're available from the <a href="http://dri.sf.net/" target="_parent">DRI</a> project. +</p> +<p> +You can get them from CVS by doing: +<pre> +cvs -d:pserver:anonymous@pds.freedesktop.org:/cvs/dri login +(hit enter when prompted for a password) +cvs -z3 -d:pserver:anonymous@pdx.freedesktop.org:/cvs/dri co drm +</pre> +<p> +Make note of the directory in which the drm files are placed. +</p> +<p> +See the <a href="http://dri.freedesktop.org/wiki/Building" target="_parent"> +DRI Building Instructions</a> for the steps to build the DRM modules. +</p> +<p> +Next, in the <code>Mesa-x.y.z/configs/default</code> file, set the +<code>DRM_SOURCE_PATH</code> variable to indicate where the DRM files +are located. +</p> +<p> +Now build Mesa and the DRI drivers by running +</p> +<pre> +make linux-dri +</pre> +<p> +There are also <code>linux-dri-x86</code>, <code>linux-dri-x86-64</code>, +and <code>linux-ppc</code> configurations, optimized for those architectures. +</p> + +<p> +Finally, you'll need a DRI-enabled X server from +<a href="http://freedesktop.org/wiki/Software_2fXserver" target="_parent"> +X.org</a> or <a href="http://www.xfree86.org" target="_parent">XFree86</a>. +Visit those projects' home pages for more information. +</p> + +</li> +</ul> + + +<p> +Later, if you want to rebuild for a different configuration run +<code>make realclean</code> before rebuilding. +</p> + + +<h3>1.2 The libraries</h3> + +<p> +When compilation has finished, look in the top-level <code>lib/</code> +directory. +You'll see a set of library files similar to this: +</p> +<pre> +lrwxrwxrwx 1 brian users 10 Mar 26 07:53 libGL.so -> libGL.so.1* +lrwxrwxrwx 1 brian users 19 Mar 26 07:53 libGL.so.1 -> libGL.so.1.5.060100* +-rwxr-xr-x 1 brian users 3375861 Mar 26 07:53 libGL.so.1.5.060100* +lrwxrwxrwx 1 brian users 11 Mar 26 07:53 libGLU.so -> libGLU.so.1* +lrwxrwxrwx 1 brian users 20 Mar 26 07:53 libGLU.so.1 -> libGLU.so.1.3.060100* +-rwxr-xr-x 1 brian users 549269 Mar 26 07:53 libGLU.so.1.3.060100* +lrwxrwxrwx 1 brian users 12 Mar 26 07:53 libglut.so -> libglut.so.3* +lrwxrwxrwx 1 brian users 16 Mar 26 07:53 libglut.so.3 -> libglut.so.3.7.1* +-rwxr-xr-x 1 brian users 597754 Mar 26 07:53 libglut.so.3.7.1* +lrwxrwxrwx 1 brian users 11 Mar 26 08:04 libGLw.so -> libGLw.so.1* +lrwxrwxrwx 1 brian users 15 Mar 26 08:04 libGLw.so.1 -> libGLw.so.1.0.0* +-rwxr-xr-x 1 brian users 20750 Mar 26 08:04 libGLw.so.1.0.0* +lrwxrwxrwx 1 brian users 14 Mar 26 07:53 libOSMesa.so -> libOSMesa.so.6* +lrwxrwxrwx 1 brian users 23 Mar 26 07:53 libOSMesa.so.6 -> libOSMesa.so.6.1.060100* +-rwxr-xr-x 1 brian users 23871 Mar 26 07:53 libOSMesa.so.6.1.060100* +</pre> + +<p> +<b>libGL</b> is the main OpenGL library (i.e. Mesa). +<br> +<b>libGLU</b> is the OpenGL Utility library. +<br> +<b>libglut</b> is the GLUT library. +<br> +<b>libGLw</b> is the Xt/Motif OpenGL drawing area widget library. +<br> +<b>libOSMesa</b> is the OSMesa (Off-Screen) interface library. +</p> + +<p> +If you built the DRI hardware drivers, you'll also see the DRI drivers: +</p> +<pre> +-rwxr-xr-x 1 brian users 11320803 Jul 21 12:11 mach64_dri.so +-rwxr-xr-x 1 brian users 11418014 Jul 21 12:12 mga_dri.so +-rwxr-xr-x 1 brian users 11064426 Jul 21 12:12 r128_dri.so +-rwxr-xr-x 1 brian users 11849858 Jul 21 12:12 r200_dri.so +-rwxr-xr-x 1 brian users 11757388 Jul 21 12:12 radeon_dri.so +-rwxr-xr-x 1 brian users 11232304 Jul 21 12:13 s3v_dri.so +-rwxr-xr-x 1 brian users 11062970 Jul 21 12:13 savage_dri.so +-rwxr-xr-x 1 brian users 11214212 Jul 21 12:13 sis_dri.so +-rwxr-xr-x 1 brian users 11368736 Jul 21 12:13 tdfx_dri.so +-rwxr-xr-x 1 brian users 10598868 Jul 21 12:13 trident_dri.so +-rwxr-xr-x 1 brian users 10997120 Jul 21 12:13 unichrome_dri.so +</pre> + + +<h3>1.3 Running the demos</h3> + +<p> +If you downloaded/unpacked the MesaDemos-x.y.z.tar.gz archive or +obtained Mesa from CVS, the <b>progs/</b> directory will contain a +bunch of demonstration programs. +</p> + +<p> +Before running a demo, you may have to set an environment variable +(such as <b>LD_LIBRARY_PATH</b> on Linux) to indicate where the +libraries are located.
