Thank you, I will investigate if I can get a windows build to work, and see how difficult it is, as we kind of want to have a single process in windows to load both OpenGL, and Mesa3D at the sometime, and the ability to use either simultaneously.

At very least the src/mesa/drivers/windows/gdi and src/gallium/targets/libgl-gdi targets will fail because the .DEF files there explicitly request the non-mangled symbols. Not sure if src/mesa/drivers/osmesa will produce something useful. You can ask scons to only build osmesa by passing "scons osmesa .." That said, there's little to zero merit in USE_MGL_NAMESPACE on Windows because on Windows it's fine to have different DLLs exporting the same symbols, since unlike Unixes, DLLs exports are not dumped into a global namespace.

I added the CFLAGS += -DUSE_MGL_NAMESPACE to the environment of the SConstruct, and the build process seems to be ok until the end when it tries to link the opengl32.dll, basically a lot of symbol not defined errors. Was wondering what is the correct way to build this mangled version of the dll?, or what step have I missed. The instructions on building the mesa3d dll that I follow is from this link http://qt-project.org/wiki/Cross-compiling-Mesa-for-Windows<https://urldefense.proofpoint.com/v2/url?u=http-3A__qt-2Dproject.org_wiki_Cross-2Dcompiling-2DMesa-2Dfor-2DWindows&d=AAMFAg&c=Sqcl0Ez6M0X8aeM67LKIiDJAXVeAw-YihVMNtXt-uEs&r=zfmBZnnVGHeYde45pMKNnVyzeaZbdIqVLprmZCM2zzE&m=6Ge3DEjWspM0_R8wmG4D9XUdqs4zKcdsmCWMwnnpm3w&s=azooVAijwKtW_999Prr91rlFVONWeD5zHoI2iIRRK80&e=> Cheers Jason Anderssen.
