[osg-users] [build] OSG with OpenGL ES 2.0 and Angle

[Andrea Pennarelli]

Hi,

I'm trying to build openscenegraph with OpenGL ES 2.0 and Angle on windows, using CMake GUI and Visual Studio 2015. I've setted the CMake variables like the page trac.openscenegraph dot org /projects/osg/wiki/Community/OpenGL-ES says. I've added the OPENGL_INCLUDE_DIR as explained in the page. I've not found the OPENGL_LIBRARY so I added it too. I've setted them to point to the Angle's include folder and Angle's libGLESv2.lib and libEGL.lib, but when I generate the project Cmake returns an error, and Visual Studio don't compile.
I receive this errors:
'glDepthRangef': identifier not found	
'GL_NUM_SHADER_BINARY_FORMATS': undeclared identifier
'GL_SHADER_BINARY_FORMATS': undeclared identifier
'glShaderBinary': identifier not found
'glClearDepthf': identifier not found

I've tried to search other guides to compile in OGL ES 2.0, but I wasn't so lucky so I decided to ask in the forum.

The final goal is to compile OSG with Angle to run it on Microsoft's HoloLens.

Thank you!

Cheers,
Andrea
