No, that line is in osgHimmel code.

Yes, and in this case the error is:

Here is the header pattern of all osgHimmel shaders under gDEBugger:

#ifndef __version__
#define __version__

#version 150 compatibility

#endif // __version__

Yes, osgShaders works fine.

5. Also, i found that link:
https://www.opengl.org/discussion_boards/showthread.php/185603-Managing-several-versions-in-a-single-shader-file
There is a solution that maybe works: somehow pass version number through API.

Or something else maybe?

Thanks for help and patience!

Cheers,
Elias
