[vtkusers] vtkQt linking errors

[David Thompson]

Hi,

I'm trying to run some of the examples included in the vtkQt package by
Matthias Koenig on Windows using Visual C++ 6, and I am having trouble
linking them. I have created a static library out of vtkQt, and I am using
qmake to create a  Visual C++ project.

Here is my qmake setup for the Cone.cxx example:

SOURCES = Cone.cxx
CONFIG  += qt thread opengl debug
DEFINES += QT_DLL
INCLUDEPATH += .. $(VTKDIR)/Graphics $(VTKDIR)/Imaging $(VTKDIR)/Common
$(VTKDIR)/Patented $(VTKDIR)/Rendering $(VTKDIR)/Filtering $(VTKDIR)
TMAKE_LIBS
+= -L.. -lvtkqt -L$(VTKBIN) -lvtkGraphics -lvtkImaging -lvtkCommon -lvtkRend
ering -lvtkFiltering
TMAKE_LFLAGS += /nodefaultlib:"msvcrt" /nodefaultlib:"libc"
TARGET  = Cone

Here are the errors I get when compiling with Visual C++ 6:

Does anybody have any idea what might be causing this, and how I can fix it?
