[vtkusers] Problems linking with OpenGL on SUN ultra 2

[Donald Tournier]

Hi!

I am pretty sure OpenGL has installed correctly - I got the OpenGl 1.2.1
package from the SUN website a few days ago and ran their
'ogl_install_check' program, everything was fine. I did have problems with
configure, since it didn't recognise the OpenGL includes. I finally
managed to compile VTK by editing the system.make file to add
'-DVTK_USE_OGLR -L/usr/openwin/include/GL' to the GRAPHICS_API_FLAGS line.
I was assuming that if the VTK build was successful, then that meant that
the libraries were recognised as OK.

Another thing which is puzzling me: all the unrecognised symbols are
actual vtk routines - they are all named as vtkOpenGLsomething. Doesn't
that mean that the problem is not with the OpenGL libraries?

Thanks again for your time,

donald
