Unsolved Link callback error OpenGL

[A Former User]

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);
