[vtkusers] Fwd: QVTK compile error with vtk 5

[Ruben Schilling]

Hi,

I am trying to compile the VTK 5.0.3 release on an X86_64 system running
SuSe Linux, gcc 4.2.0 and Qt 4.3.2. For the build I chose a 'Release' build
with a couple of optimization flags and (!) QVTK as well as GUI support. The
compilation runs fine except QVTK which gives me the following error at
compile time:

I searched the bug tracker but couldn't find this error. Does anyone have a
remedy for this or a recommendation what version of Qt would work? Is this a
version mismatch? During the configuration all Qt files seemed to be found
correctly, only Qt3 was not found (but is also not intended for usage).

I would be grateful for any hints.

Best regards
Ruben
