Mesa uses a rather conventional Makefile system.
|
|
|
|
|
A GNU autoconf/automake system used to be included, but was discarded
|
|
|
|
|
in Mesa 5.1 because:

|
<li>It seldom worked on IRIX, Solaris, AIX, etc.
|
|
|
|
|
<li>It was very compilicated
|
|
|
|
|
<li>Nobody maintained it
|
|
|
|
|
<li>libtool was just too weird
|
2003-03-08 17:38:57 +00:00

</ul>

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>

|
|
|
|
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.

Note: if you've obtained Mesa through CVS, do this first:

<p>

2004-03-26 15:20:08 +00:00
|
|
|
Just type <b>make</b> in the top-level directory.
|
2003-09-05 15:47:07 +01:00
|
|
|
You'll see a list of supported system configurations.
|
|
|
|
|
Choose one from the list (such as linux-x86), and type:

|
|
|
<p>
|
2004-03-26 15:20:08 +00:00

If you want to rebuild for a different configuration run
|
|
|
|
|
<code>make realclean</code> before rebuilding.

When compilation has finished, look in the top-level <b>lib/</b> directory.

You'll see a set of library files similar to this:

<h3>1.3 Running the demos</h3>

|
|
|
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.
|
2003-03-16 16:43:04 +00:00
|
|
|

|
|
|
<p>
|
2003-09-05 15:47:07 +01:00
|
|
|
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:
|
2003-03-16 16:43:04 +00:00
|
|
|
<p>
|
2003-09-05 15:47:07 +01:00
|
|
|
<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)
|
|
|

|
|
|
<p>
|
2003-09-05 15:47:07 +01:00
|
|
|
Next, change to the Mesa/demos/ directory:
|
2003-03-16 16:43:04 +00:00
|
|
|
</p>
|
2003-09-05 15:47:07 +01:00

|
|
|
<p>
|
2003-09-05 15:47:07 +01:00
|
|
|
Run a demo such as gears:

|
|
|
|
|
|
<p>
|
2003-09-05 15:47:07 +01:00
|
|
|
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>
|
2003-09-05 15:47:07 +01:00
|
|
|
If you're using Linux or a similar OS, verify that the demo program is
|
|
|
|
|
being linked with the proper library files:

<H3>1.4 Installing the header and library files</H3>
|
2003-03-08 17:38:57 +00:00
|
|
|
|
|
|
|
|
<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
|

<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>
|
2004-03-26 15:20:08 +00:00
|
|
|
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>
|
2004-03-26 15:20:08 +00:00
|
|
|
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.
|
2003-09-05 15:47:07 +01:00
|
|
|
This is a handy way to compare multiple OpenGL implementations.
