[osg-users] [GL ES2] Compilation errors on master branch

[Jean Baptiste Poquelin]

Hello,

I used the cmake settings for OpenGL ES 2.0.

On my machine that would be:
OSG_GL1_AVAILABLE 	OFF
OSG_GL2_AVAILABLE 	OFF
OSG_GL3_AVAILABLE 	OFF
OSG_GLES1_AVAILABLE 	OFF
OSG_GLES2_AVAILABLE 	ON
OPENGL_INCLUDE_DIR /usr/include
OPENGL_LIBRARY 	/usr/lib/x86_64-linux-gnu/libGLESv2.so
OPENGL_egl_LIBRARY 	/usr/lib/x86_64-linux-gnu/libEGL.so
OSG_GL_DISPLAYLISTS_AVAILABLE 	OFF
SG_GL_MATRICES_AVAILABLE 	OFF
OSG_GL_VERTEX_FUNCS_AVAILABLE 	OFF
OSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE 	OFF
OSG_GL_FIXED_FUNCTION_AVAILABLE 	OFF
OSG_CPP_EXCEPTIONS_AVAILABLE 	OFF 

And I get the following errors:

Can you help me figuring out why? There is no issue on OpenSceneGraph-3.2 branch.

Thank you!

Cheers,
