There really are multiple problems when trying to build with Visual Studio.<br>I tried to use SCons on Windows, but I'm not going very far with it:<br><br>1) I installed Python 3.1.2<br>2) then SCons (which detected C:\Python31 installation directory)<br>

If you really need to build Mesa 7.9 in Visual Studio, you can modify
the Visual Studio projects to get it building again. The delta between 7.8 and 7.9 is pretty
big, so it may take some effort to make these changes, but it is doable. The effort mainly consists of adding and removing files, although for Mesa 7.8, I had to add a step to compile the shader compiler and compile the pre-compiled shaders. I have not been following Mesa 7.9 that carefully, so I cannot estimate the work needed this time. There was some talk about needing to generate more files at build time using Python scripts, and that would make things harder. I also can't say when I might get around to updating the project files either.<br>
<br>
SCons seems to be the preferred tool for building Mesa for Windows,
probably because another set of build files do not have to be
maintained. It also uses the gallium softpipe and a better GDI
driver.<br>
<br>
I've tried to get Scons to work on Windows too, but ran into the same problems you did. It seems that we need better instructions for building with Scons on Windows.<br><br>Note that there is another thread in this list about using the MinGW crosscompiler toolchain on Linux.<br>
<br>The Mesa project doesn't distribute Windows binaries.<br><br>Given Scons, does anyone have any thoughts/opinions on trying to keep the Visual Studio projects going for Mesa 7.9 and beyond?<br><br>Karl<br><br>
