Hi Robert,
Hope you're feeling better today. Looks like one of the recent changes
broke the GLES2 build. Regular OpenGL profile still works fine for me.
Afraid I don't have time to work on it today, but maybe I can send in
a fix in a few days. Should be an easy one.

I'm compiling for GLES2 profile with this configuration:

ccmake .. -DOSG_GL1_AVAILABLE=OFF -DOSG_GL2_AVAILABLE=OFF
-DOSG_GL3_AVAILABLE=OFF -DOSG_GLES1_AVAILABLE=OFF
-DOSG_GLES2_AVAILABLE=ON -DOPENGL_HEADER1="#include <GLES2/gl2.h>"
-DOPENGL_HEADER2="#include <GLES2/gl2ext.h>"
-DOPENGL_egl_LIBRARY=/usr/lib64/libEGL.so
-DOSG_GL_DISPLAYLISTS_AVAILABLE=OFF -DOSG_GL_MATRICES_AVAILABLE=OFF
-DOSG_GL_VERTEX_FUNCS_AVAILABLE=OFF
-DOSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE=OFF
-DOSG_GL_FIXED_FUNCTION_AVAILABLE=OFF
-DOSG_CPP_EXCEPTIONS_AVAILABLE=ON -DCMAKE_INSTALL_PREFIX=../../..

And I get these errors during comiple:
