- README for port of Mesa to XFree86 on OS/2
- (as of 19980802)
+ README for port of Mesa 3.x to XFree86 on OS/2 (X/2)
+ (as of 19990514)
-Instructions to build Mesa for XFree86/OS2:
-You need a recent version of XFree86 (3.3x or above) installed including
-the supplied programming libraries and tools as well as EMX 0.9c (and above).
+ 1) Binary release
+ 2) Building from sources
+ 3) History
+ 4) Mesa Home Page
-Beginning after beta 7 there's again support for creating DLLs.
-The details are handled in "mklib-emx.cmd" a small REXX script.
-By now it does ensure compatiblity by using the function names as
-entry points instead of ordinals. This will cost performance and
-might be fixed in a future patch.
-We switched to the usual build method
-(based on Makefile and make-config) beginning with Mesa 3.0 beta 5.
-To use most of the standard files (including shell scripts) you should
-have a un*x shell (sh) in path.
+1) Binary release
-To actually build the (static) libraries and demos type
- make os2
+ Though Mesa 3.0 should build in a quite reasonable time on
+ a 585 class machine (or better) a binary relase is available
+ (check item 4) for an URL)
+ This package includes:
+ - lib/MesaGL.dll, MesaGL.a
+ - lib/MesaGLU.dll, MesaGLU.a
+ - lib/glut.dll, glut.a
+ - include/GL/*.h
+ Installing this in your XFree86 tree will enable you to build and
+ run all applications compatible with Mesa (and the current DLL
+ interface, of course ;-)
+ As usual the OMF-style libraries can be created using emxomf.
+ (e.g. "emxomf foo.a" creates the foo.lib omf-style library).
+ The static libraries are rarely used and you have to rebuild
+ Mesa to get them. They're a supported target, so you get
+ them in a straightforward way (see below).
+ The testing of these libraries was limited to the supplied
+ demos/examples and very few small third-party apps.
+ No warranty ... as usual ... ;-)
+2) Instructions to build Mesa 3.x for XFree86/OS2 from sources:
+ Except the official Mesa source distribution you need:
+ - a recent version of XFree86 (3.3.x or above) including
+ the programming libraries
+ - EMX 0.9c (0.9d might work, never checked)
+ - GNU make
+ - REXX (!)
+ The creation of the DLLs as well as of the static libraries
+ (if you want to have them) is handled in "mklib-emx.cmd",
+ a small REXX script. Perhaps not the best idea, but this
+ way it fits best in the scheme used to build libraries
+ on all platforms in Mesa 3.0.
+ By now binary compatiblity is ensured by using the function names
+ as entry points instead of ordinals. This might cost performance and
+ is subject to change in future. We might consider this release
+ therefore as a "demo release" to get them feedback about
+ remaining bugs.
+ To actually build the libraries and demos, check mklib-emx.cmd
+ and modify it as desired. Then type
+ make os2-x11
+ and wait for completion ;-)
+ Initially Darren Abbott (email@example.com) ported Mesa versions 2.x
+ to XFree86 OS/2. This port might still be available from
+ The current port picked up things during the beta test for 3.0.
+ No major changes in the source were done. The build mechanism under OS/2
+ has been made very similar to other platforms (if you treat mklib-emx.cmd
+ as a "black box").
+ Advantage is that X/2 is now a valid target and all files are
+ integrated in the official source distribution.
+ Disadvantage is that this port (i.e. the DLLs' interface itself) is
+ definitly NOT COMPATIBLE to those of version 2.x.
+ It's uncertain whether this would be at all possible but since there
+ a _very_ few those apps it's not worth to find out anyway.
+ Also some libs (MesaTK, MesaAUX) are withdrawn from the Mesa distribution,
+ and accordingly from the OS/2 port.
+4) Mesa Home Page
+ You can get the source code and more information about Mesa from
+ The OS/2 ports should in future be found on
