QOpenGLWidget and glDebugMessageCallback

qtyeti

Hi,

since a few days I#m working on a Qt OpenGL program. It's working fine so far (I'm using QOpenGLWidget in Qt 5.12).
Now I added some code for OpenGL debugging and for some reason I get this error message:

D:\Daten\Develop\Qt\Test\OpenGL1\newglwidget.cpp:128: Fehler: use of undeclared identifier 'glDebugMessageCallback'

I already added this include-files, but still no luck...

#include <QOpenGLExtraFunctions>
#include <QOpenGLFunctions_4_5_Core>
#include <qopenglfunctions_4_5_compatibility.h>

My graphic card supports OpenGL 4.5, so this shouldn't be the issue...

Any Ideas?

Thanks in advance,
Peter

Hi,

fixed it (in fact some days ago already):

   QOpenGLFunctions_4_5_Core *f;
.
.
    f = QOpenGLContext::currentContext()->versionFunctions<QOpenGLFunctions_4_5_Core>();
