[Mesa-users] Building Mesa 8.0.4 on Windows

[Daedalos Knossos]

Hello there,

I am currently trying to get the newest version of Mesa's Gallium
driver (8.0.4) to work on Microsoft Windows XP (32Bit). Basically I
want to run a specific OpenGL application within a virtual machine,
without hardware 3D acceleration to ensure maximum compatibility.

So far I have succeeded in building the official source code using
scons on the following machine:

-------------------------------------------
Distribution: Ubuntu 12.04 Server
Kernel: Linux 3.2.0-26-generic-pae #41-Ubuntu SMP Thu Jun 14 16:45:14
UTC 2012 i686 athlon i368 GNU/Linux
MinGW32: 4.2.1.dfsg-2ubuntu1
Scons: 2.1.0-1
Python: 2.7.3-0ubuntu2
Bison: 1:2.5.dfsg-2.1
Gcc: 4:4.6.3-1ubuntu5
libc6: 2.15-0ubuntu10
-------------------------------------------

The command I used was:
$ scons platform=windows toolchain=crossmingw machine=x86

After that, I copied the resulting "opengl32.dll" from
../mesa-8.0.4/build/windows-x86-debug/gallium/targets/libgl-gdi

To the same directory as the OpenGL application I want to run. (which
in fact uses only a Subset of OpenGL).

As soon as I start the application, I am greeting with the following
error message:
-------------------------------------------
Assertion failed!
Program: ...Executable.exe
File: src/mesa/program/program.c
Line: 432

Expression: prog->Target == 0x8620
-------------------------------------------

I have to say that, when building Mesa3D 7.0.0 using the Makefile.mgw
the application at least starts up correctly, but does not display
anything (this is why I wanted to try a newer release).

In addition to that, I was not successful in building Mesa3D 8.0.x on
Windows, so I just tried to build it on Linux instead. (which worked
like a charm btw.)

Do you have any clues or advice how I should proceed to diagnose the problem?

Sincerely yours,

George Rider.
