[osg-users] Arggh! Frustrating compiler error! OS X XCode3.0.

[Stephen Northcott]

Hi Stephan,

Thanks, that makes sense.

Suggestion one is a little hard as glew gets upset if it's not put  
together before gl.h etc.

Suggestion 2 & 3 are both viable as a fix.

I'll ping the Glew people about it also. Ultimately I'd like to move  
away from Glew and rely on OSG for that, but I can't right now.

Kind regards,
Stephen.
