[Insight-users] QtITK Problem

[Gheorghe Postelnicu]

Hi Julien,

Thanks alot for the help!

Now I seem to have some linking problems. I should mention that I am using
ccmake version 2.2-patch 2 and I receive the following errors:

--

I have seen you mention that this was a known problem with CMake 2.0.2 not
wrapping cpp for Qt, so I uncommented the relevant lines. So now my
CMakeLists.txt looks like this:

--
PROJECT(QtITKExample)

#IF( BUILD_OUTSIDE_INSIGHT_APPLICATIONS )

FIND_PACKAGE(ITK)
IF(ITK_FOUND)
INCLUDE(${ITK_USE_FILE})
ELSE(ITK_FOUND)
MESSAGE(FATAL_ERROR
"Cannot build InsightApplications without ITK. Please set ITK_DIR.")
ENDIF(ITK_FOUND)

#ENDIF( BUILD_OUTSIDE_INSIGHT_APPLICATIONS )

#
# Find QT
#
INCLUDE (${CMAKE_ROOT}/Modules/FindQt.cmake)

INCLUDE_DIRECTORIES(
${QT_INCLUDE_DIR}
${QT_INCLUDE_PATH}
)

LINK_LIBRARIES (
ITKIO
ITKCommon
ITKBasicFilters
ITKAlgorithms
ITKIO
itkpng
itkzlib
${QT_QT_LIBRARY}
)

SET(QtITK_SRCS
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)

QT_WRAP_CPP(QtITK ${QtITK_SRCS} ${QtITK_MOC_SRCS})
ADD_EXECUTABLE(QtITK ${QtITK_SRCS})

#ADD_EXECUTABLE(QtITK QtITK_SRCS)

#INSTALL_TARGETS(/bin QtITK)

Thanks for the help,
