Unix/X11 Compilation and Installation</H1> <a name="prereq-general"> <h3>1.1 General prerequisites for building</h3> <ul> <li>lex / yacc - for building the GLSL compiler. On Linux systems, flex and bison are used. Versions 2.5.35 and 2.4.1, respectively, (or later) should work. </li> <li>python - Python is needed for building the Gallium components. Version 2.6.4 or later should work. </li> </ul> <a name="prereq-dri"> <h3>1.2 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>1.3 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>1.4 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>1.5 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 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>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 16895413 Jul 21 12:11 i915_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 </pre> <p> If you built with Gallium support, look in lib/gallium/ for Gallium-based versions of libGL and device drivers. </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.
