[vtkusers] VTK 6.3 in Qt Creator

[Gib Bogle]

Hi David,

On this page http://www.vtk.org/Wiki/VTK/Build_System_Migration#How_Implementation_Modules_Are_Initialized
I found these lines

#include <vtkAutoInit.h>

VTK_MODULE_INIT(vtkRenderingOpenGL);

VTK_MODULE_INIT(vtkInteractionStyle);


which when added to the source file using VTK solved the problem.  I confess it's beyond my level of C++ understanding, so this was just luck.
I'll take it, though.


Cheers
Gib

Hi Gib,

The error might go away if you link to the vtkRenderingOpenGL library.
For more info, see the following web page:
http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Factories_now_require_defines

I set up one of the students here to use QtCreator with a cmake project,
and it worked quite well (especially because it allowed the student to
use the Qt graphical debugger).  The cmake/QtCreator combination
is not as straightforward as qmake/QtCreator, but it's probably a better
solution for VTK apps.

Getting there ... the linking now completes without error.  But when I run the program I get this:

Generic Warning: In ..\..\..\VTK-6.3.0\Rendering\Core\vtkRenderer.cxx, line 46
Error: no override found for 'vtkRenderer'.

Generic Warning: In ..\..\..\VTK-6.3.0\Rendering\Core\vtkRenderWindow.cxx, line 40
Error: no override found for 'vtkRenderWindow'.

Can some kind soul explain what this means?

Thanks
Gib

I use cmake everywhere except for building Qt programs, so I understand what you are saying.  I really like Qt Creator, though.

I have linked a lot more libraries, and now I'm down to only 3 unresolved externals:

vtkRenderingCore-6.3.lib(vtkAreaPicker.obj) : error LNK2019: unresolved external symbol "public: static class vtkExtractSelectedFrustum * __cdecl vtkExtractSelectedFrustum::New(void)" (?New at vtkExtractSelectedFrustum@@SAPAV1 at XZ) referenced in function "protected: __thiscall vtkAreaPicker::vtkAreaPicker(void)" (??0vtkAreaPicker@@IAE at XZ)

release\scell_GUI.exe : fatal error LNK1120: 3 unresolved externals

I'm trying to track down the required library.

For what it's worth, I gave up on this after an hour of trying and switched
to cmake. Haven't looked back since...
