I'm getting this weird runtime crash when instantiating QVariantAnimation or QPropertyAnimation. It appears this happens when the program doesn't link appropriately the class. But I have double checked my simple project and can't see anything wrong.

Qt Code: 
  1. #include <QtCore/QVariantAnimation>
  2. #include <QtCore/QEasingCurve>
  3.  
  4. class MyAnimacion : public QVariantAnimation {
  5. public:
  6. 	MyAnimacion() : QVariantAnimation()	{}
  7. 	~MyAnimacion(){}
  8. 	void updateCurrentValue( const QVariant & value ) {}
  9. };
  10. int main() {
  11. 	MyAnimacion myAnimacion;
  12. 	return 0;
  13. }

I don't know if QVariantAnimation is restricted to QtGui, I'm trying to use it to manually update the position of stuff in my game with the keyValueAt method.
