[Insight-users] QtImageViewer: link error

[flockmock at gmail.com]

hi,
I want to build the Qt test-application QtImageViewer from InsightApplications/Auxiliary and I get the following error:

Linking CXX executable QtSlicer
CMakeFiles/QtSlicer.dir/QtGlSliceView.cxx.o: In function `~QtGlSliceView':

make[2]: *** [QtSlicer] Error 1

I am using ITK and InsightApplications 3.12.0 and Qt-4.5.1. Does anyone know, how to avoid this? 

thanks, florian
