<P><FONT SIZE=2>Hi Sean,<BR>
<BR>
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:<BR>
<BR>
void PivotCalibrationFLTKWidgetExampleUI::InitializeTrackingAndCalibration() {<BR>
}<BR>
<BR>
<BR>
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.<BR>

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

Hi Sean,<BR>
<BR>
which FLTK version do you use?<BR>
<BR>
IGSTK is compatible with FLTK versions 1.1.X<BR>
Best,<BR>

I am getting this link error when I building the calibration example.<BR>

<BR>
But suppose that those two functions are pure virtual functions and would be overridden in PivotCalibrationFLTKWidgetExample.<BR>
<BR>
Any ideas what are happening? Thanks.<BR>
