[vtkusers] VTK on HP UX 11.0

[R K Shyamprakash]

Hello,
	I am trying to build VTK 4.2.0 on HP UX11.0 with java wrappers ON. I am
using gcc compiler. CMake configured without any error, but while compiling
I get the following error and compilation stops.

Building object file FTBitmapGlyphRenderOpenGL.o...
In file included from /opt/graphics/OpenGL/include/GL/gl.h:1692,
                 from /u/VTK-4.2.0/Utilities/ftgl/src/FTGLgl.h:25,
                 from
/u/VTK-4.2.0/Utilities/ftgl/src/FTBitmapGlyphRenderOpenGL.cpp:2:
		/opt/graphics/OpenGL/include/GL/glHpInt.h:34: syntax error before `char'
		/opt/graphics/OpenGL/include/GL/glHpInt.h:973: syntax error before `char'

Is it necessary to get Mesa3D if I am not using HP compiler? If yes, Can
some body point me a URL where I can download Mesa3D for HP UX 11.0.

Thanks
