<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>
<p>
<b> 0.</b> 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:
</p>
<pre>
autoconf 2.50
automake 1.4-p2
libtool 1.4
</pre>
<p>
<b>1.</b> Run the configure script
</p>
<pre>
./configure [options]
</pre>
<p>
For Linux, it is recommended that you use:
</p>
<pre>
./configure --prefix=/usr
</pre>
So that the headers and libs are located according to the Linux/OpenGL
standard spec at http://oss.sgi.com/projects/ogl-sample/ABI/
</p>
<p>
For Red Hat 8.0, Mandrake 9.1 and other Linux distros, you may have to use
the following:
</p>
<pre>
export LDFLAGS="-lstdc++" ; ./configure --prefix=/usr
or
setenv LDFLAGS -lstdc++ ; ./configure --prefix=/usr
</pre>
<p>
This works around a problem when building the GLU library. It needs to
be linked with the C++ runtime library, but libtool (for some reason)
doesn't do this.
</p>
<pre>
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.
</pre>
<p>
User specific compiler options can be set using the shell variable
CFLAGS. For instance,
</p>
<pre>
CFLAGS="-g -O2" ./configure
</pre>
<p>
(on some systems: env CFLAGS="-g -O2" ./configure)
sets the compiler flags to "-g -O2".
</p>
<p>
For more options run "./configure --help" and read INSTALL.GNU.
</p>
<p>
<b>2.</b> To build the Mesa libraries run:
</p>
<pre>
make
</pre>
<p>
When finished, libGL.so will be in src/.libs/ and libGLU.so will be in
si-glu/.libs/, etc.
</p>
<p>
Optionally, you can strip the libraries using
</p>
<pre>
make strip
</pre>
<p>
Now make sure that you have the permissions to install Mesa in the
specified directories, for example, by becoming super user ("su")
Then run:
</p>
<pre>
make install
</pre>
<p>
Mesa is now installed.
Please don't move the installed files but rerun all installation
steps if you want to use other directories.
</p>
<p>
<b>3.</b>To test whether Mesa works properly you might want to run the
Mesa demos:
</p>
<pre>
make check
</pre>
<p>
Builds all demos.
</p>
<pre>
make exec
</pre>
<p>
Builds and executes all demos.
</p>
<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>
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>
(for example <code>make linux-x86</code>).
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.
