-If you're not using a variant of Unix with X11, see the -Supported Systems and Drivers section -for instructions. -
+-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: -
+Mesa uses a rather conventional Makefile system. +A GNU autoconf/automake system used to be included, but was discarded +in Mesa 5.1 because: +
demos, xdemos, samples and book
-(if you downloaded the Mesa demos package.)
+- 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: +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.
-- autoconf 2.50 - automake 1.4-p2 - libtool 1.4 --
-1. Run the configure script
+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 configs/ which
+has an individual file for each configuration.
+One of the configs gets copied to configs/current, which
+is then included by all Makefiles.
- ./configure [options] -+ +
-For Linux, it is recommended that you use: +Note: if you've obtained Mesa through CVS, do this first:
- ./configure --prefix=/usr + cd Mesa + chmod a+x bin/mklib-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: +Just type make in the top-level directory. +You'll see a list of supported system configurations. +Choose one from the list (such as linux-x86), and type:
- export LDFLAGS="-lstdc++" ; ./configure --prefix=/usr - or - setenv LDFLAGS -lstdc++ ; ./configure --prefix=/usr + make linux-x86
-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.
+If you want to rebuild for a different configuration run
+make realclean before rebuilding.
-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. -+ + +
