opengl in 1.7 on Win7 again

["Luke J. West" <luke at west dot me dot uk>]

Hi,

I forgot to mention in my previous email that glxgears works fine - even
though my sample opengl program bombs out like this...

sh-3.2$ ./sample.bin 
freeglut (./sample.bin):  ERROR:
Internal error <Visual with necessary capabilities not found> in
function fgOpenWindow
Segmentation fault (core dumped)

Where's the first place you would check if you had this problem? *any*
help appreciated. any suggestions as to where to look or what to check
will be most helpful.

Thanks again,

Luke

Hi,

I've just installed Cygwin 1.7 (Win7 Hmoe Premium) and am trying to get
started with OpenGL.

I have a sample OpenGL program (sample.c) and I get the following.

sh-3.2$ gcc -o sample.bin sample.c -lglut -lglu -lgl

sh-3.2$ ./sample.bin 
freeglut (./sample.bin):  ERROR:  Internal error <Visual with necessary
capabilities not found> in function fgOpenWindow
Segmentation fault (core dumped)

sh-3.2$ glxinfo
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: Brian Paul
...

Any advice or suggestions would be very much appreciated

Luke
