[Mesa-dev] Error building on Windows with SCons

[Campbell Barton]

Hi There, Im trying to build Mesa so we can distribute it with
Blender3D on Windows (we already do this on Linux).

But I have have been unsable to build mesa 7.10.3
 (Latest MingW XP, tested python 2.5, 2.7)

Simply running 'm;\python25\Scripts\scons.bat'
I always get this error:
# --- snip
scons: Reading SConscript files ...

scons: warning: Ignoring missing SConscript
'build\windows-x86-debug\glut\glx\SConscript'
File "M:\Mesa-7.10.3\src\SConscript", line 13, in <module>
warning: LLVM disabled: not building llvmpipe
scons: done reading SConscript files.
scons: Building targets ...
scons: *** [build\windows-x86-debug\gallium\targets\libgl-gdi\opengl32.dll]
Source `src\gallium\state_trackers\wgl\opengl32.def' not found, needed
by target `build\windows-x86-debug\gallium\targets\libgl-gdi\opengl32.dll'.
scons: building terminated because of errors.
# --- snip

So I copied: src\mesa\drivers\windows\gldirect\opengl32.def

But then I get this error:

# --- snip

Any hints on how to resolve these problems?
