Mirek, here the compilation error :

In file included from /usr/include/GL/glx.h:336,
                 from /home/massimo/sources/upp-svn/uppsrc/GLCtrl/GLCtrl.h:12,
                 from /home/massimo/sources/upp-svn/MyApps/TestGL/TestOpenGL.cpp:1:
/usr/include/GL/glxext.h:714: error: typedef �Upp::Status� is initialized (use decltype instead)
/usr/include/GL/glxext.h:714: error: �PFNGLXGETTRANSPARENTINDEXSUNPROC� was not declared in this scope

The glext.h is included AFTER upp namespace opening because of your defines in X11 stuffs :

#ifndef _GLCtrl_GLCtrl_h
#define _GLCtrl_GLCtrl_h

#include <CtrlLib/CtrlLib.h>

#include <GL/gl.h>
#include <GL/glu.h>

NAMESPACE_UPP

#ifdef PLATFORM_X11
	#include <GL/glx.h>
#endif

If I include after I have tons of errors.
Now, with the #define we spoke about :

#ifdef PLATFORM_X11
	#define Status GLStatus
	#include <GL/glx.h>
	#undef Status
#endif

the error is almost the same :

In file included from /usr/include/GL/glx.h:336,
                 from /home/massimo/sources/upp-svn/uppsrc/GLCtrl/GLCtrl.h:13,
                 from /home/massimo/sources/upp-svn/uppsrc/GLCtrl/GLPicking.cpp:1,
                 from /home/massimo/sources/upp-svn/out/GLCtrl/GCC.Debug.Debug_full.Gui.Shared/$blitz.cpp:3:
/usr/include/GL/glxext.h:714: error: typedef �Upp::GLStatus� is initialized (use decltype instead)
/usr/include/GL/glxext.h:714: error: �PFNGLXGETTRANSPARENTINDEXSUNPROC� was not declared in this scope

The best would be of course include glext BEFORE upp namespace :

#ifdef PLATFORM_X11
	#define Status GLStatus
	#include <GL/glx.h>
	#undef Status
#endif

NAMESPACE_UPP

But then I get tons of errors because of your #defines in X11 core. If I replicate all those defines :

#ifdef PLATFORM_X11
	#define Time    XTime
	#define Font    XFont
	#define Display XDisplay
	#define Picture XPicture
	#define Status GLStatus
	#include <GL/gl.h>
	#include <GL/glu.h>
	#include <GL/glx.h>
	#undef Status
	#undef Picture
	#undef Time
	#undef Font
	#undef Display
#else
	#include <GL/gl.h>
	#include <GL/glu.h>
#endif

I get tons of errors, AND the same error as before at end.

Quite out of ideas ....
