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

[Robert Osfield]

Hi Jean,

I have just had a look on my Kubuntu 15.04 system and do a build using:

 cd OpenSceneGraph
 cmake .  -DOPENGL_PROFILE=GLES2
 make

And I get the same errors as you.  Previously I've used GLES2 other
headers rather than the ones that now come as part of Kubuntu/Ubuntu
and there are older and different.  The new headers add the GLuint64
definition, unfortunately I haven't yet spotted an easy way to detect
which set of headers are in use and enable/disable the typedef
accordingly.

I'd welcome suggestions.

Robert.
