First, thanks Gerd.
In x11/blit.c, line 556, wouldn't it be nice a:
ext = glGetString(GL_EXTENSIONS);
+ if (NULL == ext) {
+ fprintf (strerr, "blit: gl: no extensions available\n");
+ return 0;
+ }
if (NULL == (pos = strstr(ext,find)))
I took HAVE_LIBXV off from config.h to make opengl work, just "-noxv"
arg in command line wasn't enought.
Sorry but I'm new in OpenGL, could you help me answering why does
GL_EXTENSIONS return NULL in my system? would it be a lack of my
GeForceMX400? I don't think so, I rather think I made a mistake
somewhere.
Thanks a lot,
Fabio
