[IGSTK-Users] pure virtual function in

[Yaniv, Ziv]

Hi Sean,

This seems to be a problem with the C++ code generated by FLTK. The PivotCalibrationFLTKWidgetExampleUI.{cxx,h} are autogenerated by FLTK's fluid program from the PivotCalibrationFLTKWidgetExampleUI.fl file. In the older versions of FLTK the generated cxx file contained the following implementation of the function:

void PivotCalibrationFLTKWidgetExampleUI::InitializeTrackingAndCalibration() {
}


An empty implementation which is overridden in the descendent PivotCalibrationFLTKWidgetExample. Based on the error you get I cannot be sure what is the problem. Please take a look at the *.fl file and the code generated by fluid. You will probably need to modify the *.fl file so that the generated C++ code doesn't cause this error.

        regards
            Ziv

Thanks, Ozgur.
It was fltk-1.3.2. But how do I fix it? Can I keep this version and fix the problem?

Hi Sean, 

which FLTK version do you use?

IGSTK is compatible with FLTK versions 1.1.X
Best,

Ozgur

But suppose that those two functions are pure virtual functions and would be overridden in  PivotCalibrationFLTKWidgetExample. 

Any ideas what are happening? Thanks.
