 <H2>1. Unix/X11 Compilation and Installation</H1>

 <p>
 Mesa uses a rather conventional Makefile system.
 A GNU autoconf/automake system used to be included, but was discarded
 in Mesa 5.1 because:
 </p>
 <ul>
 <li>It seldom worked on IRIX, Solaris, AIX, etc.
 <li>It was very compilicated
 <li>Nobody maintained it
 <li>libtool was just too weird
 </ul>
 <p>
 If someone strongly feels that Mesa should have a autoconf/automake
 system and wants to contribute one and maintain it, we'll consider
 adding it again.
 </p>

 <p>
 In Mesa 6.1 we modified the conventional Makefile system.
 Instead of specifying all the various system configurations in the
 Make-config file, there's a directory named <code>configs/</code> which
 has an individual file for each configuration.
 One of the configs gets copied to <code>configs/current</code>, which
 is then included by all Makefiles.
 </p>


 <h3>1.1 Compilation</h3>

 <p>
 Note: if you've obtained Mesa through CVS, do this first:
 </p>
 <pre>
     cd Mesa
     chmod a+x bin/mklib
 </pre>

 <p>
 Just type <b>make</b> 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>
 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 <b>lib/</b> 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*

 -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>


 <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.  For example:
 <p>
 <blockquote>
 <b>cd</b> into the Mesa <b>lib/</b> directory.
 <br>
 <b>setenv LD_LIBRARY_PATH ${cwd}</b>   (if using csh or tcsh shell)
 <br>
 or,
 <br>
 <b>export LD_LIBRARY_PATH=${PWD}</b>   (if using bash or sh shell)
 </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)

         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>

 Retrace your steps if this doesn't look right.

 <H3>1.4 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>
 You'll be prompted to enter alternative directories for the headers
 and libraries.
 </p>

 <p>
 Note: at runtime, you can set the LD_LIBRARY_PATH (on Linux) to switch
 between the Mesa libs and another vendor libs whenever you want.
 This is a handy way to compare multiple OpenGL implementations.
