-
- Greetings,
-
- In order to build the Mingw32 set of Mesa 3-D Graphics Library for Beta3.08
- it will be necessary for you to use the Dos or Command Prompt that is available
- on most of the i86 based MS Windows machines. Also, I believe that this build
- will run on Win95, Win98, WinNT4 and WinNT5.
-
- I haven't tested Win95/98 or WinNT5. This build was generated under
- WinNT4 with SP3 installed.
-
- This has not been tested under any systems outside of
- a WinNT4 Workstation with EGCS-Mingw32 toolchain, v.1.0.2 installed.
-
- EGCS-Mingw32 uses a variation of gcc to handle its build. The Mesa 3-D
- Graphics Library build that I have generated is based, in small part, on the
- Cygwin32 build and associated makefiles that Stephane Rehel (rehel@worldnet.fr)
- defined back in 1997. The EGCS-Mingw32 toolchain is capable of generating
- native windows code and, as of the date of this readme, can be obtained from:
-
- http://www.xraylith.wisc.edu/~khan/software/gnu-win32/egcs-mingw32-102.html
-
- Much thanks to the combined efforts of Mumit Khan, Jan-Jaap Vanderhagen
- and Colin Peters for making it possible for the EGCS-Mingw32 toolchain to exist.
-
- Installing EGCS-Mingw32 Build Revisions:
-
- To install the makefile and source revisions incorporated with this build
- of the Mesa 3-D Graphics Library, you'll have to use a version of winzip. I am
- in the process of finding a suitable Win32 compatible tar executable so that if
- you don't have winzip, you can still decompress the files into their respective
- folders/directories.
-
- a) Move the mingw32.zip file to the top level of the hard drive on your
- system.
-
- b) Copy all of the Beta 3.08 src/windows files to the src/ directory.
-
- b) Open the Winzip file
-
- c) Verify that the files will be properly extracted.
-
- d) Extract the files with the Winzip "Overwrite" and "Use Folder Names"
- options enabled.
-
- The zip file directory structure extraction defaults to the top level of
- the hard drive where the mingw32.zip file exists unless otherwise instructed by
- you.
-
- The version of wmesa.c included with the mingw32 archive needs to replace
- the current version of the Beta 3.08 wmesa.c file in order for the egcs-mingw32
- build to work. This is because the original Win32 stuff assumes that the glut
- utilities are to be installed. The Glut utilities are not part of the
- egcs-mingw32 build for Beta 3.08.
-
-
- Build Considerations:
-
- In order to get the build to work, I needed to create a special makefile
- for each library which the Mesa 3-D Graphics Library requires since there is no
- comparable make-config/config on a native windows platform.
-
- Since I was only creating a few of the possible libraries for
- Mesa (gl, glu), I only created the new make files in their respective libraries
- src, src-glu). For libMesaaux.a. you will find a makefile for it in the
- src-aux directory. libMesatk.a and libglut.a were not ported.
-
- The build itself is a .bat based build and uses Gnu Make,Version 3.76.1 to
- process the makefiles noted above. The build must be run from the directory
- where the mingw32.bat file is. You can get the binary version of Make 3.76.1
- from Jan-Jaap van der Heijden's site in Germany:
-
- http://agnes.dida.physik.uni-essen.de/~janjaap/mingw32/download.html
-
- It was necessary to modify some source code, specifically the source code
- in the src-glu directory. I needed to modify nurbs.c, quadric.c and tess.c in
- order to get them to work using the EGCS-Mingw32 toolchain.
-
- The original EGCS-Mingw32 Toolchain, is available from:
-
- http://www.xraylith.wisc.edu/~khan/software/gnu-win32/egcs-mingw32-102.html
-
- Running the Build:
-
- Ok, now that we've got the basics out of the way, follows is all you need
- to do in order to build the EGCS-Mingw32 version of libMesaGL.a and libMesaGLU.a:
-
- Open your Command Prompt/Dos prompt.
- Go to your Mesa-3.0 beta 'root' directory.
- This is the same directory that the Mesa mingw32.zip file was
- originally stored in if you've installed the Mesa-3.0 beta 3-D
- Graphics Library source as outlined in the "readme" file included
- with the Mesa-3.0 beta distribution.
- At the command line type: mingw32
- mingw32 is the .bat file that actually does the build.
-
- Enjoy!
-
- Peace,
