Basic Usage</h2> + +<p> +The autoconf generated configure script can be used to guess your +platform and change various options for building Mesa. To use the +configure script, type: +</p> + +<pre> + ./configure +</pre> + +<p> +To see a short description of all the options, type <code>./configure +--help</code>. If you are using a development snapshot and the configure +script does not exist, type <code>make configure</code> to generate it +first. Once you have run <code>./configure</code> and set the options to +your preference, type: +</p> + +<pre> + make +</pre> + +<p> +This will produce libGL.so and several other libraries depending on the +options you have chosen. Later, if you want to rebuild for a different +configuration run <code>make realclean</code> before rebuilding. +</p> + +<p> +Some of the generic autoconf options are used with Mesa: + +<ul> +<li><code>--prefix=PREFIX</code> - This is the root directory where +files will be installed by <code>make install</code>. The default is +<code>/usr/local</code>. +</li> +<li><code>--exec-prefix=EPREFIX</code> - This is the root directory +where architecture-dependent files will be installed. In Mesa, this is +only used to derive the directory for the libraries. The default is +<code>${prefix}</code>. +</li> +<li><code>--libdir=LIBDIR</code> - This option specifies the directory +where the GL libraries will be installed. The default is +<code>${exec_prefix}/lib</code>. It also serves as the name of the +library staging area in the source tree. For instance, if the option +<code>--libdir=/usr/local/lib64</code> is used, the libraries will be +created in a <code>lib64</code> directory at the top of the Mesa source +tree. +</li> +<li><code>--enable-static, --disable-shared</code> - By default, Mesa +will build shared libraries. Either of these options will force static +libraries to be built. It is not currently possible to build static and +shared libraries in a single pass. +</li> +<li><code>CC, CFLAGS, CXX, CXXFLAGS</code> - These environment variables +control the C and C++ compilers used during the build. By default, +<code>gcc</code> and <code>g++</code> are used with the options +<code>"-g -O2"</code>. +</li> +<li><code>LDFLAGS</code> - An environment variable specifying flags to +pass when linking programs. These are normally empty, but can be used +to direct the linker to use libraries in nonstandard directories. For +example, <code>LDFLAGS="-L/usr/X11R6/lib"</code>. +</li> +<li><code>PKG_CONFIG_PATH</code> - When available, the +<code>pkg-config</code> utility is used to search for external libraries +on the system. This environment variable is used to control the search +path for <code>pkg-config</code>. For instance, setting +<code>PKG_CONFIG_PATH=/usr/X11R6/lib/pkgconfig</code> will search for +package metadata in <code>/usr/X11R6</code> before the standard +directories. +</li> +</ul> +</p> + +<p> +There are also a few general options for altering the Mesa build: +<ul> +<li><code>--with-x</code> - When the X11 development libraries are +needed, the <code>pkg-config</code> utility <a href="#pkg-config">will +be used</a> for locating them. If they cannot be found through +<code>pkg-config</code> a fallback routing using <code>imake</code> will +be used. In this case, the <code>--with-x</code>, +<code>--x-includes</code> and <code>--x-libraries</code> options can +control the use of X for Mesa. +</li> +<li><code>--enable-debug</code> - This option will enable compiler +options and macros to aid in debugging the Mesa libraries. +</li> +<li><code>--disable-asm</code> - There are assembly routines +available for a few architectures. These will be used by default if +one of these architectures is detected. This option ensures that +assembly will not be used. +</li> +</ul> +</p> + + +<a name="driver"> +<h2>2. Driver Options</h2> + +<p> +There are several different driver modes that Mesa can use. These are +described in more detail in the <a href="install.html">basic +installation instructions</a>. The Mesa driver is controlled through the +configure option --with-driver. There are currently three supported +options in the configure script. +</p> + +<ul> + +<a name="xlib"> +<li><b><em>Xlib</em></b> - This is the default mode for building Mesa. +It uses Xlib as a software renderer to do all rendering. It corresponds +to the option <code>--with-driver=xlib</code>. The libX11 and libXext +libraries, as well as the X11 development headers, will be need to +support the Xlib driver. +</li> + +<!-- Xlib specific options --> +<p> +<ul> +<li><code>--disable-xlib-osmesa</code> - By default, the OSMesa library +will be built and linked to the Xlib enabled libGL. This option disables +building of libOSMesa. +</li> +</ul> +</p> + +<a name="dri"> +<li><b><em>DRI</em></b> - This mode uses the DRI hardware drivers for +accelerated OpenGL rendering. Enable the DRI drivers with the option +<code>--with-driver=dri</code>. See the <a href="install.html">basic +installation instructions</a> for details on prerequisites for the DRI +drivers. +</li> + +<!-- DRI specific options --> +<p> +<ul> +<li><code>--with-dri-driverdir=DIR</code> - This option specifies the +location the DRI drivers will be installed to and the location libGL +will search for DRI drivers. The default is +<code>/usr/X11R6/lib/modules/dri</code>. +</li> +<li><code>--with-dri-drivers=DRIVER,DRIVER,...</code> - This option +allows a specific set of DRI drivers to be built. For example, +<code>--with-dri-drivers="i965,radeon,nouveau"</code>. By default, +the drivers will be chosen depending on the target platform. See the +directory <code>src/mesa/drivers/dri</code> in the source tree for +available drivers. +</li> +<!-- This explanation might be totally bogus. Kristian? --> +<li><code>--disable-driglx-direct</code> - Disable direct rendering in +GLX. Normally, direct hardware rendering through the DRI drivers and +indirect software rendering are enabled in GLX. This option disables +direct rendering entirely. It can be useful on architectures where +kernel DRM modules are not available. +</li> +<li><code>--enable-glx-tls</code> - Enable Thread Local Storage (TLS) in +GLX. +</li> +<li><code>--with-expat=DIR</code> - The DRI-enabled libGL uses expat to +parse the DRI configuration files in <code>/etc/drirc</code> and +<code>~/.drirc</code>. This option allows a specific expat installation +to be used. For example, <code>--with-expat=/usr/local</code> will +search for expat headers and libraries in <code>/usr/local/include</code> +and <code>/usr/local/lib</code>, respectively. +</li> +</ul> +</p> + +<a name="osmesa"> +<li><b><em>OSMesa</em></b> - No libGL is built in this +mode. Instead, the driver code is built into the Off-Screen Mesa +(OSMesa) library. See the <a href="osmesa.html">Off-Screen Rendering</a> +page for more details. +</li> + +<!-- OSMesa specific options --> +<p> +<ul> +<li><code>--with-osmesa-bits=BITS</code> - This option allows the size +of the color channel in bits to be specified. By default, an 8-bit +channel will be used, and the driver will be named libOSMesa. Other +options are 16- and 32-bit color channels, which will add the bit size +to the library name. For example, <code>--with-osmesa-bits=16</code> +will create the libOSMesa16 library with a 16-bit color channel. +</li> +</ul> +</p> + +</ul> + + +<a name="library"> +<h2>3. Library Options</h2> + +<p> +The configure script provides more fine grained control over the GL +libraries that will be built. More details on the specific GL libraries +can be found in the <a href="install.html">basic installation +instructions</a>. + +<ul> +<a name="glu"> +<li><b><em>GLU</em></b> - The libGLU library will be built by default +on all drivers. This can be disable with the option +<code>--disable-glu</code>. +</li> + +<a name="glw"> +<li><b><em>GLw</em></b> - The libGLw library will be built by default +if libGLU has been enabled. This can be disable with the option +<code>--disable-glw</code>. +</li> + +<a name="glut"> +<li><b><em>GLUT</em></b> - The libglut library will be built by default +if libGLU has been enabled and the glut source code from the MesaGLUT +tarball is available.

Demo Program Options</h2> + +<p> +There are many demonstration programs in the MesaDemos tarball. If the +programs are available when <code>./configure</code> is run, a subset of +the programs will be built depending on the driver and library options +chosen. See the directory <code>progs</code> for the full set of demos. + +<ul> +<li><code>--with-demos=DEMOS,DEMOS,...</code> - This option allows a +specific set of demo programs to be built. For example, +<code>--with-demos="xdemos,slang"</code>. Beware that if this option is +used, it will not be ensured that the necessary GL libraries will be +available. +</li> +<li><code>--without-demos</code> - This completely disables building the +demo programs.
