[Insight-users] [ITK Community] Hello ITK with Qt Creator issue

Fri Mar 7 03:41:31 EST 2014

Hi Alok,

Finally we decided to go with CMake and left the idea of working with QMake format, since CMake is more widespread and powerful.

Idea was to use itkImage and some ITK filter such as http://www.itk.org/Doxygen/html/classitk_1_1AdaptiveHistogramEqualizationImageFilter.html

But the Hello World just tests linkage is correct. So here are the files, anyways.

QMake file : http://pastebin.com/UwfGEqNs (I define « ITK » environment variable as my installation directory)

CMake file : http://pastebin.com/g3yjy8is works perfectly but I wonder why it detected ITK in my build directory rather than installation one since I have boths on my machine. I can see this in project files tree in Qt Creator.

main.cpp : http://pastebin.com/Y9MvdK1s

Have a nice day,

Hi Barbara,

In my opinion getting a Hello World running ITK should not need linking to too many libraries.
Can you share your current source(.cpp) and Qmake/Cmake file?

Hello again,

Yesterday I went back to my ITK Hello World project based on QMake. I checked libs linkages because my compilation issue is about linkage. I have the following issue: in the QMake project file below I have linkage to ITKBiasCorrection library, as Jothy gave me a list of libs to link against. But in my build/install tree I cannot find neither the header nor the lib matching  ITKBiasCorrection. So my CMake options were incomplete. ITKBioCell exists, however.

Here is my CMake configuration, using CMake-GUI I went to advanced mode.

-          ITK_BUILD_DEFAULT_MODULES: checked

-          Module_ItkVtkGlue: checked

So I clearly miss something to get ITKBiasCorrection build.
Since list of libs is lengthy and I really don't know much, what's your best advice to get a rich but not obese ITK build?

Do you think the following list is a minimal set of required libs?

I'm going to search now for build options but your input is welcome.

Hello again,

After compiling VTK, ITK with vtkGlue enabled, I still have troubles when using ITK in a QMake project.

Now the error changed to this one, surprisingly:

ITKCommon-4.5.lib(itkDynamicLoader.obj):-1: error: LNK2019: unresolved external symbol "public: static struct HINSTANCE__ * __cdecl itksys::DynamicLoader::OpenLibrary(char const *)" (?OpenLibrary at DynamicLoader@itksys@@SAPEAUHINSTANCE__@@PEBD at Z) referenced in function "public: static struct HINSTANCE__ * __cdecl itk::DynamicLoader::OpenLibrary(char const *)" (?OpenLibrary at DynamicLoader@itk@@SAPEAUHINSTANCE__@@PEBD at Z)

File not found: ITKCommon-4.5.lib(itkDynamicLoader.obj)

It's really strange because I didn't modify the directories paths and the files are there as expected.

My .pro file, again:

# Pass information to Qmake (include path)
INCLUDEPATH += $$PWD/../../../../../../ITK/include/ITK-4.5
DEPENDPATH += $$PWD/../../../../../../ITK/include/ITK-4.5

# Pass information to Qmake (lib path)
#QMAKE_LIBDIR += \
#    $${ITK_LIBS}
#C:/ITK/lib

# Pass information to Qmake (link against)
win32: LIBS += -L$$PWD/../../../../../../ITK/lib/ \
-lITKBiasCorrection-4.5 \
-lITKBioCell-4.5 \
-lITKCommon-4.5 \
[... list of libs]

My ITK folder is in C:
$$PWD shoud refer to C:\Dev\Projects\MyProject\HelloItk\qmake\HelloItk folder where I have the .pro file.
So why are there 6 "../" instructions in path to climb up, rather than 5 ones ? If I put only 5 "../", it won't find itkImage.h.

I guess I have libs references not in correct order.

Almost going to give up in favor of CMake project :-) so this is my last call to feedback about people who used a QMake project.

Thanks,
