Error while link libraries between Qt and ITK.

[Deepak Murali]

Hai all,

I want to develop a image processing and visualization software. So i tried to integrate vtk and itk to qt. Unfortunately there is an error occurred while link libraries of itk to Qt. the error is "itksys-4.13.lib(SystemTools.obj):-1: error: LNK2019: unresolved external symbol". But the lib itksys-4.3 is exist in the pro file. The complete error given below.

itksys-4.13.lib(SystemTools.obj):-1: error: LNK2019: unresolved external symbol __imp_OpenProcessToken referenced in function "bool __cdecl itksys::DeleteJunction(class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > const &)" (?DeleteJunction@itksys@@YA_NAEBV?$basic_string@_WU?$char_traits@_W@std@@V?$allocator@_W@2@@std@@@Z)

And also the qt pro file details given below.

I tried many ways to sort out the issue. But still it exist. Any body please help me to sort out the issues.

Thanks in advance

Hi and welcome to devnet,

Did you check that the libraries are from the right architecture ?

Which compiler are you using ?
Which compiler was used to build itk ?

[Deepak Murali]

@SGaist yes i checked. msvc 2015 64bit. the same i used to build itk.

[SGaist]

Did you check the linker output ? Does it contain the required library ?

[mchinand]

ITK is much easier to work with if you use CMake instead of qmake .pro project files. Your link command is missing a library that would have been automatically added to the linking if you used CMake.
