-If you're not using a variant of Unix with X11, see the -Supported Systems and Drivers section -for instructions. +Mesa uses a rather conventional Makefile system. +A GNU autoconf/automake system used to be included, but was discarded +in Mesa 5.1 because:
- --There are two methods for building Mesa on Unix/X11 systems: -
- -make and you'll see a list of supported
-system configurations. Pick one and type make config.
-More details below.
--NOTE: 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. -
- --In either case, building Mesa entails the following: -
demos, xdemos, samples and book
-(if you downloaded the Mesa demos package.)

You'll need these programs - to run the bootstrap script: +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.

-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/ - -
-For Red Hat 8.0, Mandrake 9.1 and other Linux distros, you may have to use -the following: -
-- export LDFLAGS="-lstdc++" ; ./configure --prefix=/usr - or - setenv LDFLAGS -lstdc++ ; ./configure --prefix=/usr --
-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. -
--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 --
(on some systems you may need to run gmake or
-gnumake instead)
-
-When finished, libGL.so will be in src/.libs/ and 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. -
- - - -
-This procedure usually works when ./configure ; make fails.
-
-Note: If you tried ./configure ; make but it failed,
-first copy the top-level Makefile.X11 file over
-Makefile.
-
-Also Note: if you've obtained Mesa directly from CVS you'll have -to copy the top-level Makefile.X11 to Makefile. -
- -
-Just type make alone.
+Now, just type make.
You'll see a list of supported system configurations.
-Choose one and type make config
-(for example make linux-x86).
-The Mesa libraries and demo programs will be compiled.
+Choose one from the list (such as linux-x86), and type:
+
+ make linux-x86 ++
+That's it.
