      Hi I want to use "glDebugMessageCallback" but I didn't found how make it.

      In some tuto it explaine like that :

      void OpenGLCallback( GLenum source, GLenum type, GLuint id, GLenum severity, GLsizei length, const GLchar *msg, const void *data )
      {
          std::cout << "debug call: " << msg << std::endl;
      }
      
      void Paint::SetContext(QOpenGLContext* context)
      {
          OpenGLFunction = context->versionFunctions<QOpenGLFunctions_4_3_Core>();
          glDebugMessageCallback = (PFNGLGENBUFFERSARBPROC) context->getProcAddress("glDebugMessageCallback");
          if (glDebugMessageCallback)
      	    glDebugMessageCallback(OpenGLCallback, NULL);
          else
      	    std::cout << "ERROR : Impossible to load glDebugMessageCallback" << std::endl;
      }
      

      But this code didn't works :(
      error C2664: 'void (GLsizei,GLuint *)' : cannot convert argument 1 from 'void (__cdecl *)(GLenum,GLenum,GLuint,GLenum,GLsizei,const GLchar *,const void *)' to 'GLsizei'

      Best regards,
      Robin

        Hi,

        AFAIK it should be glDebugMessageCallback(&OpenGLCallBack, NULL);
