<TITLE>Compilation and Installation</TITLE>
<BODY text="#000000" bgcolor="#55bbff" link="#111188">
<H1>Compilation and Installation for Unix/X11</H1>
<p>
If you're not using a variant of Unix with X11, see the
<a href="systems.html">Supported Systems and Drivers</a> section
for instructions.
</p>
<p>
There are two methods for building Mesa on Unix/X11 systems:
</p>
<dl>
<dt><a href="#new">NEW-STYLE</a><dt>
<dd>
Basically, type "./configure" followed by "make"
This <em>should</em> work on most Unix-like operating systems.
Unfortunately, autoconf/automake seems to seldom work reliably on non-Linux
systems. For that reason, the old-style make system is still supported
(and is the preferred method of the Mesa developers).
</dd>
<br>
<dt><a href="#old">OLD-STYLE</a><dt>
<dd>
Simply type <code>make</code> and you'll see a list of supported
system configurations. Pick one and type <code>make</code> <em>config</em>.
More details below.
</dd>
</dl>
<p>
<B>NOTE</b>: The GLUT library and demonstrations programs are in the
MesaDemos-x.y.z.tar.gz file. If you don't have GLUT or you want to
run some demos, download the MesaDemos package too.
</p>
<p>
In either case, building Mesa entails the following:
<p>
<ul>
<li>Compiling libGL, the OpenGL-replacement library.
<li>Compiling libGLU, the OpenGL Utility library.
<li>Compiling libglut, the GLUT library (if you downloaded the Mesa demos
package)
<li>Compiling the demonstration programs in the directories:
<code>demos, xdemos, samples</code> and <code>book</code>
(if you downloaded the Mesa demos package.)
</ul>
<a name="new">
<H2>NEW-STYLE compilation and installation</H2>
<pre>
0) If you've downloaded Mesa via CVS there will not be a "configure"
script. You'll have to run the "bootstrap" script first. This script
may not work on any OS other than Linux. You'll need these programs
to run the bootstrap script:
autoconf 2.50
automake 1.4-p2
libtool 1.4
1) Run the configure script
./configure [options]
For Linux, it is recommended that you use:
./configure --prefix=/usr
So that the headers and libs are located according to the Linux/OpenGL
standard spec at http://oss.sgi.com/projects/ogl-sample/ABI/
Possible options are:
--prefix=DIR
The toplevel directory of the hierachy in which Mesa
will be installed (DIR/include,DIR/lib etc.).
The default is "/usr/local".
--sysconfdir=DIR
The directory where Mesa configuration files
will be stored. The default is "$prefix/etc".
You may want to overwrite the default with --sysconfdir=/etc.
--enable-static
Enable building of static libraries.
Static libraries are NOT built by default.
--disable-shared
Disable building of shared libraries.
Shared libraries are built by default.
--with-pic
--without-pic
In normal operation, libtool will build shared libraries from
PIC objects and static archives from non-PIC objects, except where one
or the other is not provided by the target host. By specifying
--with-pic you are asking libtool to build static archives from
PIC objects, and similarly by specifying --without-pic you are asking
libtool to build shared libraries from non-PIC objects.
libtool will only honour this flag where it will produce a
working library, otherwise it reverts to the default.
--enable-debug
Enable debugging messages (disabled by default).
--enable-profile
Enable profiling (disabled by default).
--disable-optimize
Disable extra optimizations (enabled by default,
i.e., optimize for maximum performance).
--enable-warn
Enable extended compiler warnings (disabled by default).
--enable-x86[=ARG]
--disable-x86
Enable/disable x86 assembler support to speed up Mesa
(autodetected by default). You may set `on' or `off'.
--enable-3dnow[=ARG]
--disable-3dnow
Enable/disable 3Dnow support to speed up Mesa
(autodetected by default). You may set `on' or `off'.
--enable-mmx[=ARG]
--disable-mmx
Enable/disable MMX support to speed up Mesa
(autodetected by default). You may set `on' or `off'.
--enable-sse[=ARG]
--disable-sse
Enable/disable SSE support to speed up Mesa
(autodetected by default). You may set `on' or `off'.
If you have a PentiumIII and want to use SSE make sure you have the
PIII Linux kernel-patch installed or things will fail!
You can get the patch from http://www.redhat.com/~dledford/linux_kernel.html
--with-glide[=DIR]
--without-glide
Enable/disable support for Glide (disabled by default).
DIR is the installation directory of Glide.
If Glide cannot be found, the driver won't be built.
--with-glut[=DIR]
--without-glut
Don't/use already-installed GLUT (autodetected by default).
DIR is the installation directory of Glut.
If GLUT cannot be found, the version shipped with Mesa will be built.
--with-ggi[=DIR]
--without-ggi
Enable/disable support for GGI (autodetected by default).
DIR is the installation directory of GGI.
If GGI cannot be found, the driver won't be built.
--disable-ggi-fbdev
Don't build the GGI fbdev target (autodetected by default).
--disable-ggi-genkgi
Don't build the GGI generic KGI driver (autodetected by default).
--disable-ggi-savage4
Don't build the GGI Savage4 KGI driver (autodetected by default).
--disable-osmesa
Disable OSmesa (offscreen rendering) support (enabled by default).
--with-svga[=DIR]
--without-svga
Enable/disable support for SVGALib (autodetected by default).
DIR is the installation directory of SVGALib.
If SVGALib cannot be found, the driver won't be built.
--x-includes=DIR
Search for the X include files in DIR.
--x-libraries=DIR
Search for the X library files in DIR.
User specific compiler options can be set using the shell variable
CFLAGS. For instance,
CFLAGS="-g -O2" ./configure
(on some systems: env CFLAGS="-g -O2" ./configure)
sets the compiler flags to "-g -O2".
For more options run "./configure --help" and read INSTALL.GNU.
2) To build the Mesa libraries run:
make
When finished, libGL.so will be in src/.libs/, libGLU.so will be in
si-glu/.libs/, etc.
Optionally, you can strip the libraries using
make strip
Now make sure that you have the permissions to install Mesa in the
specified directories, for example, by becoming super user ("su")
Then run:
make install
Mesa is now installed.
Please don't move the installed files but rerun all installation
steps if you want to use other directories.
3) To test whether Mesa works properly you might want to run the Mesa demos:
make check
Builds all demos.
make exec
Builds and executes all demos.
</pre>
<a name="old">
<H2>OLD-STYLE compilation and installation</H2>
<p>
This procedure usually works when <code>./configure ; make</code> fails.
</p>
<p>
<b>Note</b>: If you tried <code>./configure ; make</code> but it failed,
first copy the top-level <code>Makefile.X11</code> file over
<code>Makefile</code>.
</p>
<p>
First, just type <code>make</code> alone.
You'll see a list of supported system configurations.
Choose one and type <code>make</code> <em>config</em>.
The Mesa libraries and demo programs will be compiled.
</p>
<H3>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:
<pre>
cp -r include/GL /usr/include
</pre>
<p>
To install the Mesa libraries, do this:
</p>
<pre>
cp -pd lib/* /usr/lib
(The -pd options preserve symbolic links)
</pre>
<H3>LD_LIBRARY_PATH</H3>
<p>
On Linux and similar operating systems the <code>LD_LIBRARY_PATH</code>
environment variable can be used to indicate a list of directories to
search for shared libraries.
If you don't install Mesa in <code>/usr/lib/</code> you may have to
set the <code>LD_LIBRARY_PATH</code> variable in order to use the Mesa
libraries.
