Ok, manually adding OPENGL_INCLUDE_DIR works. We've configured for egl, but at link time, it still appears to be referring to wgl functions. I found this message from two years ago: http://forum.openscenegraph.org/viewtopic.php?t=4208view=previous where you say I've only written EGL support for GraphicsWindowX11.cpp, and don't have any access to a Windows or OSX system so can't directly help there. Members of the community will have to dive in and add EGL support to src/osgViewer/GraphicsWindowWin32.cpp to enable OpenGL ES under Windows. Can anyone confirm -- am I missing something, or in two years nobody has built GLES on Windows and written the egl stubs for GraphicsWindowWin32? I'm going to go dissect GraphicsWindowWin32 now and see what I can learn. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging. OpenGL.

[osg-users] Building on OpenGL ES
The instructions at: http://www.openscenegraph.org/projects/osg/wiki/Community/OpenGL-ES seem out of date. There is no mention in the CMake files of an OPENGL_INCLUDE variable. There is no mention of OSG_GLU_AVAILABLE. Does anyone have a current, correct, set of build instructions for OpenGL ES (2.0)? We'll be building Windows with the PowerVR emulation library, if it matters. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging. OpenGL.
