Newbie question about cross compiling mesa3d on Linux for Windows7

Hi all!

I need OpenGL 2.0 or better support for an old notebook (intel 945 gpu). So I found out, that mesa could be a solution.
I cross compiled latest version on my ubuntu 12.10 box (with scons and mingw32), which worked without any errors.

In the result, I had my windows folder under build, where many libs and dll where saved. My problem now: which do I need in the local path of my application? I first just copied opengl32.dll from mesa/drivers/windows, but received an exception about illegal access in my applications (which is openRA, see http://openra.res0l.net/) log. Sorry, can't copy the original exception now, notebook is not, where I am now ;-) I could deliver that tomorrow, if someone needs it.

Any hints for me?

Cheers,
Joern
