[vtkusers] libvtkRendering.so.5.6: undefined symbol: _ZN8QMapData10createDataEi

[Jeff Baumes]

A quick google search turned up this page:

http://www.slicer.org/slicerWiki/index.php/Slicer3:Developers:Projects:QtSlicer/Tutorials/CompileWithQt

Which states:

"if you encounter compilation errors like undefined reference to
`QMapData::createData(int)', delete the entire build directory
(VTK-build) and start a build from scratch (you can use the same
CMakeCache.txt) Make sure there is not a different Qt version in the
PATH/LD_LIBRARY_PATH environment variables (ie Qt-4.6.0 while you try
to compile VTK with 4.6.2)."

HTH,
Jeff
