I’ve got a program that I’ve been working on and off on for some time trying out various things. I’m compiling under cygwin and using VBOs.
I just updated my cygwin installation and now my opengl32.a doesn’t contain the VBO functions glBufferData etc. and my w32api/gl*.h headers don’t have the prototypes.
As far as I can see there are no w32api versions of these that support the VBO functions. I can only assume that when I first set it all up (about a year ago) I had problems getting it to work and copied over the above files with some library that I must have downloaded or compiled from somwhere (not very smart I know).
I’m pretty sure it wasn’t using Mesa3D, but I could be wrong. I’ve tried that and the headers and libGL.a do have the VBO functions, but now my glut functions and undeclared at link time. Though I can’t see why since nm on glut32.a shows they are there.
Basically I’ve stuffed my installation (which I seem to have hacked together in the first place) and I’m looking for help to get it back. My makefile had
-l glut32 -l glu32 -l opengl32
I’ve installed Mesa3d and changed it to
-l glut32 -l glu32 -L /usr/local/lib -l GL
but that now gives me
‘undefined reference to _glutInit’
and all the other glut functions.
I don’t really understand the whole w32api/opengl/GL/Mesa/glut/freeGlut/etc thing so any help would be much appreciated.
