[Insight-users] QtITK Bluiding problem (linking problem) please help

[Adem breckon]

Hi

I want to run QtITK ( taken from InsightApplications) as I want to do a Qt
based Gui for my itk application.

I used the following CMakeLists file:

PROJECT(myProject)



FIND_PACKAGE ( ITK)

IF ( ITK_FOUND)

INCLUDE( ${USE_ITK_FILE} )

ENDIF( ITK_FOUND)





# Find QT

FIND_PACKAGE( Qt4   REQUIRED )

#INCLUDE( ${QT_USE_FILE} )



INCLUDE_DIRECTORIES(

  ${QT_INCLUDES}

  ${QT_INCLUDE_DIR}

  ${QT_QTGUI_INCLUDE_DIR}

  ${QT_QTCORE_INCLUDE_DIR}

  ${CMAKE_CURRENT_BINARY_DIR}

  ${CMAKE_CURRENT_SOURCE_DIR}

  )





LINK_LIBRARIES (QtITK

${ITK_LIBRARIES}

${QT_LIBRARIES}

${QT_QTCORE_LIBRARY}

${QT_QTGUI_LIBRARY}

)





SET( QtITK.cpp itkQtProgressBar.cxx qtITK.cxx)



SET( QtITK_MOC_SRCS itkQtAdaptor.h itkQtLightIndicator.h)



#IF(QT_WRAP_CPP)

 # QT_WRAP_CPP(QtITK QtITK_SRCS QtITK_MOC_SRCS)

#ENDIF(QT_WRAP_CPP



ADD_EXECUTABLE( QtITK QtITK.cpp)



I successfully configured it using cmake and when I try to build the
solution using VS 2008 I got the following link errors:

Of course I have putt all the files needed in my bin directory:
itkQtProgressBar.cxx,
itkQtProgressBar.h itkQtAdaptor.h, itkQtLightIndicator.h


but still got this linking problem. I used  qt4.8.5 and itk 4.4.2
version,  Cmake
(2.8.11.2),  VS. 2008.

I am using QtITK from InsightApplications-4.4.0.


I searched in itk mailing list and I found two messages asking the same
question

in http://www.itk.org/pipermail/insight-users/2004-July/009627.html

they suggest that CMake  not wrapping cpp for Qt.

As you can see in my CMakeLists file, I already comment out that but still
having the same errors.



In http://www.itk.org/pipermail/insight-users/2005-November/015684.html

The author said that moc has not run properly on the appropriate
headers (itkQtAdaptor.h,
itkQtLightIndicator.h) so he has done this manually and the problem is
resolved.



I don’t really know the meaning of that and how to do it.



Could you please help as I am really stack in using QT with itk. No
application is running for me. I have already posted my problem with
QtImageViewer
and I still waiting or help.

Does anyone have a working application wusing itk and QT…please help.

Adem.
