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.

Common scons options:
build=release machine=x86 platform=windows libgl-gdi
Linux (Debian Wheezy), toolchain=crossmingw: Fails during linking phase because it can't find __vscprintf, among other things. Works as of Debian Jessie 8.5 & Mesa d2f42a945ec0fbcc51b59cfd329258bd62ebf0d2 via:
scons \ toolchain=crossmingw \ build=release \ machine=x86 \ platform=windows \ libgl-gdi
DLL is installed to build/windows-x86/gallium/targets/libgl-gdi/opengl32.dll
Windows, toolchain=mingw: Fails with "The command line is too long." despite multiple permutations of both snippits on LongCmdLinesOnWin32.
Windows, VS2012 Express, MSVC_VERSION=11.0: Succeeds after removing stray C99-isms from src/glsl/ralloc.c::ralloc_size().
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:
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.
