-Installing GCC-2.95.2/Mingw32 Build:
-
- a) Open the file archive (either tar.gz or .zip extensions)
-
- b) Decide the directory you want to move the archived files to.
-
- d) Extract the files from the archive.
-
- e) Edit the mingw32.bat file to accomodate your choice of directory structure.
-
- %mesaroot%: This is your root directory (Mesa-3.3)
- %mesasrc%: This is the Mesa-3.3 src directory (Mesa-3.3\src)
- %mesalib%: This is where the build will put libGL.a and libGLU.a
-
-Running the Build:
-
- Open your Command Prompt or MS-DOS prompt.
- Go to your Mesa-3.3 'root' directory
- At the command line type: mingw32
-
- That's all there is to it.

- Enjoy!
