[vtkusers] vtkPNGReader (0x8089a00): Unable to open file ../../../../VTKData/Data/vtk.png

[Jorge Alberto Segura Mestas]

Hello
I have compile de ImageViewer example from /VTK/Examples/GUI/Qt/ImageViewer
and this is the output of the compiler:

csnmgeek at csnmgeek-desktop:~/vtk/VTK/Examples/GUI/Qt/ImageViewer$ cmake .

Scanning dependencies of target qtimageviewer
[100%] Building CXX object CMakeFiles/qtimageviewer.dir/main.o
Linking CXX executable qtimageviewer

But when I run it, I get this error:

csnmgeek at csnmgeek-desktop:~/vtk/VTK/Examples/GUI/Qt/ImageViewer$
./qtimageviewer
ERROR: In /home/csnmgeek/vtk/VTK/IO/vtkPNGReader.cxx, line 43
vtkPNGReader (0x8089a00): Unable to open file
../../../../VTKData/Data/vtk.png

Is this a bug?
Or
I'm doing something wrong?

regards
