I went through all the steps on the compiling / installing page on Mesa's site, and read the FAQ. The final command that you send to scons for compilation throws errors within python scripts. This is my output. What am I doing wrong? Also if anyone has compiled dll's for mesa using up to date mesa and mingw, or VS2012, then please share!
Here is my output, I haven't programmed python in a long time but it appears a map/dictionary doesn't contain the key/value pair.

EDIT: More complete procedure:
Install Visual Studio Express 2012 for Windows Desktop:
http://www.microsoft.com/visualstudio/eng/downloads#d-express-windows-desktop
Install MinGW:
http://www.mingw.org/
http://sourceforge.net/projects/mingw/files/
http://sourceforge.net/projects/mingw/files/latest/download?source=files
mingw-get-inst-20120426.exe
Run installer:
Download latest repo catalogs
Install to C:\MinGW (default)
Check:
* C compiler
* C++ compiler
* MSYS basic system
* MinGW developer toolkit (should install msys-flex and msys-bison)
Install Python 2.7:
http://www.python.org/download/
http://www.python.org/ftp/python/2.7.5/python-2.7.5.msi
You have to use 32-bit Python because the Scons people only distribute 32-bit installers.
Install for all users (default)
Install to C:\Python27 (default)
Use default install options/customizations
Install libxml2
for Python:
http://www.lfd.uci.edu/~gohlke/pythonlibs/
libxml2-python-2.9.1.win32-py2.7.exe
Installer should find the python install automagically
Install pywin32
:
http://pywin32.sourceforge.net/
http://sourceforge.net/projects/pywin32/files/pywin32/
http://sourceforge.net/projects/pywin32/files/pywin32/Build%20218/
http://sourceforge.net/projects/pywin32/files/pywin32/Build%20218/pywin32-218.win32-py2.7.exe
Installer should find the Python install automagically
Install Scons
:
http://www.scons.org/
http://prdownloads.sourceforge.net/scons/scons-2.3.0-setup.exe
Installer should find the Python install automagically
Add these near the top of your PATH
:
C:\Python27\
C:\Python27\Scripts
Download Mesa:
ftp://ftp.freedesktop.org/pub/mesa/
ftp://ftp.freedesktop.org/pub/mesa/9.1.5/MesaLib-9.1.5.zip
Extract somewhere (C:\Mesa-9.1.5)
Start MSYS shell:
C:\mingw\msys\1.0\msys.bat
Change into mesa src directory:
cd /c/Mesa-9.1.5/
Build Mesa:
scons.py \
build=release \
machine=x86 \
platform=windows \
MSVC_VERSION=11.0 \
libgl-gdi \
This should create an opengl32.dll
in build\windows-x86\gallium\targets\libgl-gdi
.
With a little bit more legwork it's possible to build llvmpipe
.
