[Resolved] link error when using QVTKWidget under QtCreator

[cerina]

Hi all,
I tried to use QVTKWidget in my application. I used the design to promote the class QVTKWidget to my widget.But, when i compile my program, i got this error:
@FenClient.obj:-1: erreur : LNK2019: unresolved external symbol "public: __thiscall QVTKWidget::QVTKWidget(class QWidget *,class QFlags<enum Qt::WindowType>)" (??0QVTKWidget@@QAE@PAVQWidget@@V?$QFlags@W4WindowType@Qt@@@@@Z) referenced in function "public: void __thiscall Ui_FenClient::setupUi(class QWidget *)" (?setupUi@Ui_FenClient@@QAEXPAVQWidget@@@Z)@

and this one :
@release\client.exe:-1: erreur : LNK1120: 1 unresolved externals@
Even, when i add the libs to my .pro file , i still have these errors :
@LIBS += -LC:/vtkqt/lib/vtk-5.8 -lvtkWidgets
-LC:/vtkqt/lib/vtk-5.8 -lvtkCharts
-LC:/vtkqt/lib/vtk-5.8 -lvtksys
-LC:/vtkqt/lib/vtk-5.8 -lvtkGeovis
-LC:/vtkqt/lib/vtk-5.8 -lvtkViews
-LC:/vtkqt/lib/vtk-5.8 -lvtkInfovis
-LC:/vtkqt/lib/vtk-5.8 -lvtkVolumeRendering

-LC:/vtkqt/lib/vtk-5.8 -lvtkIO
-LC:/vtkqt/lib/vtk-5.8 -lvtkCommon
-LC:/vtkqt/lib/vtk-5.8 -lvtkProj4

Any help please and thanks

Hi,

Did you make a clean and call qmake once again? Sometimes it helps to clean old makefiles manually from build directory.
