This build has been tested under WinNT4/SP6. Win9x and WinNT5 remain untested by me. I have not tested any of the demos included with Mesa3d.

|

Greetings,
|
||||
I recommend using the GCC-2.95.2/Mingw32.
|
||||
|
||||
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:

||||

|
||||
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:
|
||||
Installing GCC-2.95.2/Mingw32 Build:
|
||||
|
||||
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) Open the file archive (either tar.gz or .zip extensions)
|
||||
|
||||
a) Move the mingw32.zip file to the top level of the hard drive on your
|
||||
system.
|
||||
b) Decide the directory you want to move the archived files to.
|
||||
|
||||
b) Copy all of the Beta 3.08 src/windows files to the src/ directory.
|
||||
d) Extract the files from the archive.
|
||||
|
||||
e) Edit the mingw32.bat file to accomodate your choice of directory structure.
|
||||
|
||||
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
|
||||
%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:
|
||||
|
||||
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.
|
||||
Open your Command Prompt or MS-DOS prompt.
|
||||
Go to your Mesa-3.3 'root' directory
|
||||
At the command line type: mingw32
|
||||
mingw32 is the .bat file that actually does the build.
|
||||
|
||||
That's all there is to it.
|
||||
|
||||
Enjoy!
