- - - -

1. Unix/X11 Compilation and Installation

- - - -

1.1 General prerequisites for building

- -
    -
  • lex / yacc - for building the GLSL compiler. -On Linux systems, flex and bison are used. -Versions 2.5.35 and 2.4.1, respectively, (or later) should work. -
    • -
  • python - Python is needed for building the Gallium components. -Version 2.6.4 or later should work. -
    • -
- - - -

1.2 Prerequisites for DRI and hardware acceleration

- -

-The following are required for DRI-based hardware acceleration with Mesa: -

- -
    -
  • dri2proto version 1.99.3 or later -
  • Linux 2.6.28 -
  • libDRM -version 2.4.15 or later -
  • Xorg server version 1.5 or later -
-

- - - -

1.3 Building with Autoconf

- -

-Mesa may be built using autoconf. -This should work well on most GNU-based systems. -If that fails the traditional Mesa build system is available. - - - - -

1.4 Building with traditional Makefiles

- -

-The traditional Mesa build system is based on a collection of pre-defined -system configurations. -

-

-To see the list of configurations, just type make. -Then choose a configuration from the list and type make -configname. -

- -

-Mesa may be built in several different ways using the predefined configurations: -

-
    -
  • Stand-alone/Xlib mode - Mesa will be compiled as -a software renderer using Xlib to do all rendering. -The libGL.so library will be a self-contained rendering library that will -allow you to run OpenGL/GLX applications on any X server (regardless of -whether it supports the GLX X server extension). -You will not be able to use hardware 3D acceleration. -

    -To compile stand-alone Mesa 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: -

    -
    -    make linux-x86
-
    -

    This will produce libGL.so and several other libraries

    -
    • - -
  • DRI/accelerated - The DRI hardware drivers for -accelerated OpenGL rendering (for ATI, Intel, Matrox, etc) will be built. -The libGL.so library will support the GLX extension and will load/use -the DRI hardware drivers. - - -

    -Build Mesa and the DRI hardware drivers by running -

    -
    -   make linux-dri
-
    -

    -There are also linux-dri-x86, linux-dri-x86-64, -and linux-ppc configurations which are optimized for those -architectures. -

    -

    -Make sure you have the prerequisite versions of DRM and Xserver mentioned -above. -

    - -
    • - -
- - -

-Later, if you want to rebuild for a different configuration run -make realclean before rebuilding. -

- - - -

1.5 The libraries

- -

-When compilation has finished, look in the top-level lib/ -(or lib64/) directory. -You'll see a set of library files similar to this: -

-
-lrwxrwxrwx    1 brian    users          10 Mar 26 07:53 libGL.so -> libGL.so.1*
-lrwxrwxrwx    1 brian    users          19 Mar 26 07:53 libGL.so.1 -> libGL.so.1.5.060100*
--rwxr-xr-x    1 brian    users     3375861 Mar 26 07:53 libGL.so.1.5.060100*

--rwxr-xr-x    1 brian    users      549269 Mar 26 07:53 libGLU.so.1.3.060100*
-lrwxrwxrwx    1 brian    users          12 Mar 26 07:53 libglut.so -> libglut.so.3*
-lrwxrwxrwx    1 brian    users          16 Mar 26 07:53 libglut.so.3 -> libglut.so.3.7.1*
--rwxr-xr-x    1 brian    users      597754 Mar 26 07:53 libglut.so.3.7.1*
-lrwxrwxrwx    1 brian    users          14 Mar 26 07:53 libOSMesa.so -> libOSMesa.so.6*
-lrwxrwxrwx    1 brian    users          23 Mar 26 07:53 libOSMesa.so.6 -> libOSMesa.so.6.1.060100*
--rwxr-xr-x    1 brian    users       23871 Mar 26 07:53 libOSMesa.so.6.1.060100*
-
- -

-libGL is the main OpenGL library (i.e. Mesa). -
-libGLU is the OpenGL Utility library. -
-libglut is the GLUT library. -
-libOSMesa is the OSMesa (Off-Screen) interface library. -

- -

-If you built the DRI hardware drivers, you'll also see the DRI drivers: -

-
--rwxr-xr-x   1 brian users 16895413 Jul 21 12:11 i915_dri.so
--rwxr-xr-x   1 brian users 11849858 Jul 21 12:12 r200_dri.so
--rwxr-xr-x   1 brian users 16050488 Jul 21 12:11 r300_dri.so
--rwxr-xr-x   1 brian users 11757388 Jul 21 12:12 radeon_dri.so
-
- -

-If you built with Gallium support, look in lib/gallium/ for Gallium-based -versions of libGL and device drivers. -

- - - - -

1.6 Installing the header and library files

- -

-The standard location for the OpenGL header files on Unix-type systems is -in /usr/include/GL/. -The standard location for the libraries is /usr/lib/. -For more information see, the - -Linux/OpenGL ABI specification. -

- -

-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 -/usr/local/include/GL/ and /usr/local/lib/. -

- -

-To install Mesa's headers and libraries, run make install. -But first, check the Mesa/configs/default file and examine the values -of the INSTALL_DIR and DRI_DRIVER_INSTALL_DIR variables. -Change them if needed, then run make install. -

- -

-The variable -DESTDIR may also be used to install the contents to a temporary -staging directory. -This can be useful for package management. -For example: make install DESTDIR=/somepath/ -

- -

-Note: at runtime you can use the LD_LIBRARY_PATH environment variable -(on Linux at least) to switch -between the Mesa libraries and other vendor's libraries whenever you want. -This is a handy way to compare multiple OpenGL implementations. -

- - - -

1.7 Building OpenGL programs with pkg-config

- -

-Running make install will install package configuration files -for the pkg-config utility. -

- -

-When compiling your OpenGL application you can use pkg-config to determine -the proper compiler and linker flags. -

- -

-For example, compiling and linking a GLUT application can be done with: -

-
-   gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo
-
- -
- - -

2. Windows Compilation and Installation

- -

-Please see the instructions on building with SCons. -

- - - - -

3. Building with SCons

- -

-To build Mesa with SCons on Linux or Windows do -

-
-    scons
-
-

-The build output will be placed in -build/platform-machine-debug/..., where platform is for -example linux or windows, machine is x86 or x86_64, optionally followed -by -debug for debug builds. -

- -

-To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do -

-
-    scons platform=windows toolchain=crossmingw machine=x86 mesagdi libgl-gdi
-
-

-This will create: -

Compiling and Installing

+ +
    +
  1. Unix / X11 + +
  2. Windows +
  3. Building with SCons +
  4. Other +
+
+ + + +

1. Unix/X11 Compilation and Installation

+ + + +

1.1 General prerequisites for building

+ +
    +
  • lex / yacc - for building the GLSL compiler. +On Linux systems, flex and bison are used. +Versions 2.5.35 and 2.4.1, respectively, (or later) should work. +
    • +
  • python - Python is needed for building the Gallium components. +Version 2.6.4 or later should work. +
    • +
+ + + +

1.2 Prerequisites for DRI and hardware acceleration

+ +

+The following are required for DRI-based hardware acceleration with Mesa: +

+ +
    +
  • dri2proto version 1.99.3 or later +
  • Linux 2.6.28 +
  • libDRM +version 2.4.15 or later +
  • Xorg server version 1.5 or later +
+

+ + + +

1.3 Building with Autoconf

+ +

+Mesa may be built using autoconf. +This should work well on most GNU-based systems. +If that fails the traditional Mesa build system is available. + + + + +

1.4 Building with traditional Makefiles

+ +

+The traditional Mesa build system is based on a collection of pre-defined +system configurations. +

+

+To see the list of configurations, just type make. +Then choose a configuration from the list and type make +configname. +

+ +

+Mesa may be built in several different ways using the predefined configurations: +

+
    +
  • Stand-alone/Xlib mode - Mesa will be compiled as +a software renderer using Xlib to do all rendering. +The libGL.so library will be a self-contained rendering library that will +allow you to run OpenGL/GLX applications on any X server (regardless of +whether it supports the GLX X server extension). +You will not be able to use hardware 3D acceleration. +

    +To compile stand-alone Mesa 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: +

    +
    +    make linux-x86
+
    +

    This will produce libGL.so and several other libraries

    +
    • + +
  • DRI/accelerated - The DRI hardware drivers for +accelerated OpenGL rendering (for ATI, Intel, Matrox, etc) will be built. +The libGL.so library will support the GLX extension and will load/use +the DRI hardware drivers. + + +

    +Build Mesa and the DRI hardware drivers by running +

    +
    +   make linux-dri
+
    +

    +There are also linux-dri-x86, linux-dri-x86-64, +and linux-ppc configurations which are optimized for those +architectures. +

    +

    +Make sure you have the prerequisite versions of DRM and Xserver mentioned +above. +

    + +
    • + +
+ + +

+Later, if you want to rebuild for a different configuration run +make realclean before rebuilding. +

+ + + +

1.5 The libraries

+ +

+When compilation has finished, look in the top-level lib/ +(or lib64/) directory. +You'll see a set of library files similar to this: +

+
+lrwxrwxrwx    1 brian    users          10 Mar 26 07:53 libGL.so -> libGL.so.1*
+lrwxrwxrwx    1 brian    users          19 Mar 26 07:53 libGL.so.1 -> libGL.so.1.5.060100*
+-rwxr-xr-x    1 brian    users     3375861 Mar 26 07:53 libGL.so.1.5.060100*
+lrwxrwxrwx    1 brian    users          11 Mar 26 07:53 libGLU.so -> libGLU.so.1*
+lrwxrwxrwx    1 brian    users          20 Mar 26 07:53 libGLU.so.1 -> libGLU.so.1.3.060100*
+-rwxr-xr-x    1 brian    users      549269 Mar 26 07:53 libGLU.so.1.3.060100*
+lrwxrwxrwx    1 brian    users          12 Mar 26 07:53 libglut.so -> libglut.so.3*
+lrwxrwxrwx    1 brian    users          16 Mar 26 07:53 libglut.so.3 -> libglut.so.3.7.1*
+-rwxr-xr-x    1 brian    users      597754 Mar 26 07:53 libglut.so.3.7.1*
+lrwxrwxrwx    1 brian    users          14 Mar 26 07:53 libOSMesa.so -> libOSMesa.so.6*
+lrwxrwxrwx    1 brian    users          23 Mar 26 07:53 libOSMesa.so.6 -> libOSMesa.so.6.1.060100*
+-rwxr-xr-x    1 brian    users       23871 Mar 26 07:53 libOSMesa.so.6.1.060100*
+
+ +

+libGL is the main OpenGL library (i.e. Mesa). +
+libGLU is the OpenGL Utility library. +
+libglut is the GLUT library. +
+libOSMesa is the OSMesa (Off-Screen) interface library. +

+ +

+If you built the DRI hardware drivers, you'll also see the DRI drivers: +

+
+-rwxr-xr-x   1 brian users 16895413 Jul 21 12:11 i915_dri.so
+-rwxr-xr-x   1 brian users 11849858 Jul 21 12:12 r200_dri.so
+-rwxr-xr-x   1 brian users 16050488 Jul 21 12:11 r300_dri.so
+-rwxr-xr-x   1 brian users 11757388 Jul 21 12:12 radeon_dri.so
+
+ +

+If you built with Gallium support, look in lib/gallium/ for Gallium-based +versions of libGL and device drivers. +

+ + + + +

1.6 Installing the header and library files

+ +

+The standard location for the OpenGL header files on Unix-type systems is +in /usr/include/GL/. +The standard location for the libraries is /usr/lib/. +For more information see, the + +Linux/OpenGL ABI specification. +

+ +

+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 +/usr/local/include/GL/ and /usr/local/lib/. +

+ +

+To install Mesa's headers and libraries, run make install. +But first, check the Mesa/configs/default file and examine the values +of the INSTALL_DIR and DRI_DRIVER_INSTALL_DIR variables. +Change them if needed, then run make install. +

+ +

+The variable +DESTDIR may also be used to install the contents to a temporary +staging directory. +This can be useful for package management. +For example: make install DESTDIR=/somepath/ +

+ +

+Note: at runtime you can use the LD_LIBRARY_PATH environment variable +(on Linux at least) to switch +between the Mesa libraries and other vendor's libraries whenever you want. +This is a handy way to compare multiple OpenGL implementations. +

+ + + +

1.7 Building OpenGL programs with pkg-config

+ +

+Running make install will install package configuration files +for the pkg-config utility. +

+ +

+When compiling your OpenGL application you can use pkg-config to determine +the proper compiler and linker flags. +

+ +

+For example, compiling and linking a GLUT application can be done with: +

+
+   gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo
+
+ +
+ + +

2. Windows Compilation and Installation

+ +

+Please see the instructions on building with SCons. +

+ + + + +

3. Building with SCons

+ +

+To build Mesa with SCons on Linux or Windows do +

+
+    scons
+
+

+The build output will be placed in +build/platform-machine-debug/..., where platform is for +example linux or windows, machine is x86 or x86_64, optionally followed +by -debug for debug builds. +

+ +

+To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do +

+
+    scons platform=windows toolchain=crossmingw machine=x86 mesagdi libgl-gdi
+
+

+This will create: +

+
    +
  • build/windows-x86-debug/mesa/drivers/windows/gdi/opengl32.dll — Mesa + swrast, binary compatible with Windows's opengl32.dll +
  • build/windows-x86-debug/gallium/targets/libgl-gdi/opengl32.dll — Mesa + Gallium + softpipe, binary compatible with Windows's opengl32.dll +
+

+Put them all in the same directory to test them. +

I'm pleased to announce that I've accepted a position with Precision Insight, -Inc. effective October, 1999. I'll be leaving Avid Technology in September.

-

I've been working on Mesa in my spare time for over five years. With Precision -Insight I now have the opportunity to devote my full attention to advancing Mesa -and OpenGL on Linux.

-

While I'll be focused on Linux, the X Window System, and hardware acceleration, -my work will continue to be open sourced and available to any other programmers who -may want to contribute to it, or use it for other projects or platforms

-

PS: I'm going to be traveling until Sep 6 and won't be reading email until then.

May 1999 - John Carmack of id Software, Inc. has made a donation of
-US$10,000 to the Mesa project to support its continuing development.
-Mesa is a free implementation of the OpenGL 3D graphics library and id's
-newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
-
-The donation will go to Keith Whitwell, who has been optimizing Mesa to
-improve performance on 3d hardware.  Thanks to Keith's work, many
-applications using Mesa 3.1 will see a dramatic performance increase
-over Mesa 3.0.  The donation will allow Keith to continue working on
-Mesa full time for some time to come.
-
-For more information about Mesa see www.mesa3d.org.  For more
-information about id Software, Inc. see www.idsoftware.com.

I'm pleased to announce that I've accepted a position with Precision Insight, +Inc. effective October, 1999. I'll be leaving Avid Technology in September.

+

I've been working on Mesa in my spare time for over five years. With Precision +Insight I now have the opportunity to devote my full attention to advancing Mesa +and OpenGL on Linux.

+

While I'll be focused on Linux, the X Window System, and hardware acceleration, +my work will continue to be open sourced and available to any other programmers who +may want to contribute to it, or use it for other projects or platforms

+

PS: I'm going to be traveling until Sep 6 and won't be reading email until then.

May 1999 - John Carmack of id Software, Inc. has made a donation of
+US$10,000 to the Mesa project to support its continuing development.
+Mesa is a free implementation of the OpenGL 3D graphics library and id's
+newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
+
+The donation will go to Keith Whitwell, who has been optimizing Mesa to
+improve performance on 3d hardware.  Thanks to Keith's work, many
+applications using Mesa 3.1 will see a dramatic performance increase
+over Mesa 3.0.  The donation will allow Keith to continue working on
+Mesa full time for some time to come.
+
+For more information about Mesa see www.mesa3d.org.  For more
+information about id Software, Inc. see www.idsoftware.com.

+--------------------------------
+
+This donation from John/id is very generous.  Keith and I are very
+grateful.
