If I put printf("HELLO MESA\n"); into wglGetProcAddress it prints it, so
some code from Mesa is certainly being executed.
The reason why I suspect that I have a windows dll loaded is that when
it calls wglGetProcAddress("wglMakeContextCurrentARB") it seems to be
inside a small DLL, while mesa is like 18mbytes. It doesn't look like
mesa's dll at all to me... Is there any way I can tell for sure?

Thanks for the reply.
Ok, I have a few new findings:
- It seems that I was wrong, the function that it fails to get the address
of is actually wglMakeContextCurrentARB!
Afacit Mesa (st/wgl) does not advertise WGL_ARB_make_current_read,
hence why the function pointer is NULL.
if the program does not check for the extension alongside the
eglGetProcAddress, then it's broken and you'd need to either
a) address that in the program
b) or, add support for the extension in st/wgl
- Inside opengl32.dll I see it keeps getting the pointer and deleting it
until it finally returns 0
- The thing is... I don't know if that's Mesa or windows's opengl32.dll. I
am very sorry, I really suck at debugging low level code
Simple printf("HELLO MESA\n"); or similar will tell you exactly
where/what you're using.
If someone here has some skill at using stuff like IDA pro, I will happily
send all the files so we can work together.
Since you've got the code for Mesa you really don't need any such
tools. But if anyone's interested to help you out they know how to
contact you.
I won't be able to offer much more help, I'm afraid.
