weird..

[JacquesOlivierLachaud]

Is there any other information ? I am even surprised that I include Qt in testSetFunctions !!

[kerautret]

it comes from the qmetatype.h which belongs to the QTCore group, here is the qt part mentioned with the "constant expression expected":

[JacquesOlivierLachaud]

But why QT is included after SetFunctions ? And I remember putting operator| into namespace DGtal::functions.

[kerautret]

It comes from the common.h ... (due to DrawableWithViewer3D)
