<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>
<h3>1.1 Compilation</h3>
<p>
If you've obtained Mesa through CVS, do this to first:
</p>
<pre>
cd Mesa-newtree
cp Makefile.X11 Makefile
</pre>
<p>
Now, just type <b>make</b>.
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>
That's it.
</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 Sep 4 17:55 libGL.so -> libGL.so.1*
lrwxrwxrwx 1 brian users 19 Sep 4 17:55 libGL.so.1 -> libGL.so.1.4.050100*
-rwxr-xr-x 1 brian users 13940317 Sep 4 17:55 libGL.so.1.4.050100*
lrwxrwxrwx 1 brian users 11 Sep 4 17:54 libGLU.so -> libGLU.so.1*
lrwxrwxrwx 1 brian users 20 Sep 4 17:54 libGLU.so.1 -> libGLU.so.1.3.050100*
-rwxr-xr-x 1 brian users 324746 Sep 3 13:54 libGLU.so.1.1*
-rwxr-xr-x 1 brian users 2830539 Sep 4 17:54 libGLU.so.1.3.050100*
lrwxrwxrwx 1 brian users 12 Sep 4 17:53 libglut.so -> libglut.so.3*
lrwxrwxrwx 1 brian users 16 Sep 4 17:53 libglut.so.3 -> libglut.so.3.7.1*
-rwxr-xr-x 1 brian users 2426683 Sep 4 17:53 libglut.so.3.7.1*
</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.
</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)
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>
<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 the Mesa headers, do this:
<blockquote>
<b>cp -r include/GL /usr/include</b>
</blockquote>
<p>
To install the Mesa libraries, do this:
</p>
<blockquote>
<b>cp -pd lib/* /usr/lib</b>
<br>
(The -pd options preserve symbolic links)
</blockquote>
<p>
If you install the libraries in a non-standard location you can use
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.
