    Default Compile error with OpenGL: How to set parameter compilation project QtCreator 2.6.0

    Hello to all. I have a project that uses calls to OpenGL, in particular, I'm:
    Qt Code:
    1. static GLUtesselator *tobj = NULL;
    2. tobj = gluNewTess();
    3. gluTessCallback(tobj, GLU_TESS_VERTEX, (GLvoid (*) ()) &glVertex3dv);
    4. ...
    To copy to clipboard, switch view to plain text mode 
    compiling I get this error message:
    Qt Code:
    1. C:\Qt\progetti\AreaRobot\blockgroup.cpp:187: error: invalid conversion from 'GLvoid (*)() {aka void (*)()}' to '_GLUfuncptr {aka void (*)()}' [-fpermissive]
    To copy to clipboard, switch view to plain text mode 
    I do not know how I can correct the error, can you help me ?

    Remove the ampersand.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.

    The solution is this:
    Qt Code:
    1. gluTessCallback(tobj, GLU_TESS_VERTEX, (void (__stdcall *)(void))glVertex3dv);
    To copy to clipboard, switch view to plain text mode 
    ie:
    Qt Code:
    1. (void (__stdcall *)(void))glVertex3dv
    To copy to clipboard, switch view to plain text mode
