Comment 1 Thomas Lübking 2010-09-04 12:20:05 UTC

can you please

grep GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE_EXT /usr/include/GL/glext.h

since either your glext is quite outdated (ought to be there since iirc at least 2007) or there's an issue in the include chain (kwinglutils apparently don't explicitly include glext)

Thanks for getting back Thomas.   I have already tracked this missing symbol to 
glext.h and it's present.

e.g.  grep GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE_EXT /usr/include/GL/glext.h    
gives:

#define GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE_EXT 0x8D56

I have tried to include glext.h at the beginning of kwinglutils.cpp, e.g. 
#include "glext.h", but this makes no difference.

Comment 3 Thomas Lübking 2010-09-04 19:16:46 UTC

presumingly sth.s defining GL_ARB_framebuffer_object before then...

you could try to inject "#undef GL_ARB_framebuffer_object" before calling the include, but there's either sth. messed up on your side or kwin/KDE/Qt has a problem... =\

Thanks Thomas.  In the end I added #define 
GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE_EXT   0x8D56
to kwinglutils.cpp like so:

#ifdef KWIN_HAVE_OPENGL

#include "kwinglobals.h"
#include "kwineffects.h"

#include "kdebug.h"
#include <kstandarddirs.h>

#include <QPixmap>
#include <QImage>
#include <QHash>
#include <QFile>


#define DEBUG_GLRENDERTARGET 0

#define MAKE_GL_VERSION(major, minor, release)  ( ((major) << 16) | ((minor) << 
8) | (release) )
#define GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE_EXT   0x8D56

and it worked, very odd, but then I'm no programmer.

Comment 5 Martin Flöser 2012-04-08 20:41:29 UTC

4.5 is already quite some time ago and the complete stack has moved since then. I assume this issue to be resolved by now and set the bug report to UNMAINTAINED due to the old version.
