[vtkusers] vtkQt linking errors

[REGAT-BARREL Aurélien]

Hi,
I had some troubles with vtkQt and VTK 4.2 precompiled binaries.
I downloaded vtkQt here :
http://www.matthias-koenig.net/vtkqt/vtk4qt3.tgz
I downloaded and compiled VTK 4.4.
Now it works fine (I use Qt 3.3.2 and VC++ 7.1).
I compiled in Release (you are in Debug).
If you still have troubles, try to change your project "runtime library" setting (=> mono/multithread static/dll).
If it does not work, you should think about upgrading your VC++.
VC++ 6 is very old and outdated !
Download for free VC++ Toolkit 2003 and replace your cl.exe and link.exe + the libs.

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?

Thanks,
David Thompson
