Unix/X11 Compilation and Installation</H1> <a name="prereq"> <h3>1.1 Prerequisites for DRI and hardware acceleration</h3> <p> The following are required for DRI-based hardware acceleration with Mesa: </p> <ul> <li><a href="http://xorg.freedesktop.org/releases/individual/proto/">dri2proto</a> version 1.99.3 or later <li>Linux 2.6.28 <li><a href="http://dri.freedesktop.org/libdrm/" target="_parent">libDRM</a> version 2.4.15 or later <li>Xorg server version 1.5 or later </ul> </p> <a name="autoconf"> <h3>1.2 Building with Autoconf</h3> <p> Mesa may be <a href="autoconf.html">built using autoconf</a>. This should work well on most GNU-based systems. If that fails the traditional Mesa build system is available. <a name="traditional"> <h3>1.3 Building with traditional Makefiles</h3> <p> The traditional Mesa build system is based on a collection of pre-defined system configurations. </p> <p> To see the list of configurations, just type <code>make</code>. Then choose a configuration from the list and type <code>make</code> <em>configname</em>. </p> <p> Mesa may be built in several different ways using the predefined configurations: </p> <ul> <li><b><em>Stand-alone/Xlib mode</em></b> - Mesa will be compiled as a software renderer using Xlib to do all rendering. The libGL.so library will be a self-contained rendering library that will allow you to run OpenGL/GLX applications on any X server (regardless of whether it supports the GLX X server extension). You will <em>not</em> be able to use hardware 3D acceleration. <p> To compile stand-alone Mesa type <code>make</code> in the top-level directory. You'll see a list of supported system configurations. Choose one from the list (such as linux-x86), and type: </p> <pre> make linux-x86 </pre> <p>This will produce libGL.so and several other libraries</p> </li> <li><b><em>DRI/accelerated</em></b> - The DRI hardware drivers for accelerated OpenGL rendering (for ATI, Intel, Matrox, etc) will be built. The libGL.so library will support the GLX extension and will load/use the DRI hardware drivers. <p> Build Mesa and the DRI hardware 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 which are optimized for those architectures. </p> <p> Make sure you have the prerequisite versions of DRM and Xserver mentioned above. </p> </li> </ul> <p> Later, if you want to rebuild for a different configuration run <code>make realclean</code> before rebuilding. </p> <a name="libs"> <h3>1.4 The libraries</h3> <p> When compilation has finished, look in the top-level <code>lib/</code> (or <code>lib64/</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 15607851 Jul 21 12:11 ffb_dri.so -rwxr-xr-x 1 brian users 15148747 Jul 21 12:11 i810_dri.so -rwxr-xr-x 1 brian users 14497814 Jul 21 12:11 i830_dri.so -rwxr-xr-x 1 brian users 16895413 Jul 21 12:11 i915_dri.so -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 16050488 Jul 21 12:11 r300_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> <a name="demos"> <h3>1.5 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'll probably have to set two environment variables to indicate where the libraries are located. For example: <p> <blockquote> <b>cd lib/</b> <br> <b>export LD_LIBRARY_PATH=${PWD}</b> <br> <b>export LIBGL_DRIVERS_PATH=${PWD}</b> (if using DRI drivers) </blockquote> <p> Next, change to the Mesa/demos/ directory: </p> <blockquote> <b>cd ../progs/demos</b> </blockquote> <p> Run a demo such as gears: </p> <blockquote> <b>./gears</b> </blockquote> <p> If this doesn't work, try the <b>Mesa/progs/xdemos/glxinfo</b> program and see that it prints the expected Mesa version number. </p> <p> If you're using Linux or a similar OS, verify that the demo program is being linked with the proper library files: </p> <blockquote> <b>ldd gears</b> </blockquote> <p> You should see something like this: </p> <pre> libglut.so.3 => /home/brian/Mesa/lib/libglut.so.3 (0x40013000) libGLU.so.1 => /home/brian/Mesa/lib/libGLU.so.1 (0x40051000) libGL.so.1 => /home/brian/Mesa/lib/libGL.so.1 (0x400e0000) libc.so.6 => /lib/i686/libc.so.6 (0x42000000) libm.so.6 => /lib/i686/libm.so.6 (0x403da000) libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x403fc000) libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x404da000) libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x404f1000) libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x40543000) libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x4054b000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x405fd000) libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40605000) libpthread.so.0 => /lib/i686/libpthread.so.0 (0x40613000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) libdl.so.2 => /lib/libdl.so.2 (0x40644000) libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x40647000) libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x40650000) </pre> <p> Retrace your steps if this doesn't look right. </p> <a name="install"> <H3>1.6 Installing the header and library files</H3> <p> The standard location for the OpenGL header files on Unix-type systems is in <code>/usr/include/GL/</code>. The standard location for the libraries is <code>/usr/lib/</code>. For more information see, the <a href="http://oss.sgi.com/projects/ogl-sample/ABI/" target="_parent"> Linux/OpenGL ABI specification</a>. </p> <p> If you'd like Mesa to co-exist with another implementation of OpenGL that's already installed, you'll have to choose different directories, like <code>/usr/local/include/GL/</code> and <code>/usr/local/lib/</code>. </p> <p> To install Mesa's headers and libraries, run <code>make install</code>. But first, check the Mesa/configs/default file and examine the values of the <b>INSTALL_DIR</b> and <b>DRI_DRIVER_INSTALL_DIR</b> variables. Change them if needed, then run <code>make install</code>. </p> <p> The variable <b>DESTDIR</b> may also be used to install the contents to a temporary staging directory. This can be useful for package management. For example: <code>make install DESTDIR=/somepath/</code> </p> <p> Note: at runtime you can use the LD_LIBRARY_PATH environment variable (on Linux at least) to switch between the Mesa libraries and other vendor's libraries whenever you want. This is a handy way to compare multiple OpenGL implementations. </p> <a name="pkg-config"> <H3>1.7 Building OpenGL programs with pkg-config</H3> <p> Running <code>make install</code> will install package configuration files for the pkg-config utility. </p> <p> When compiling your OpenGL application you can use pkg-config to determine the proper compiler and linker flags. </p> <p> For example, compiling and linking a GLUT application can be done with: </p> <pre> gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo </pre> <br> <a name="windows"> <H2>2.
