[Insight-users] Linking problem when using itk

[李健]

Linking CXX executable testCMakeFiles/test.dir/test.o(.text+0x1be): In function `main':/home/src/itk/test.cxx:23: undefined reference to `importITK<unsigned short, 2u>::importITK(unsigned int*, unsigned short*)'CMakeFiles/test.dir/test.o(.text+0x20d):/home/src/itk/test.cxx:28: undefined reference to `importITK<unsigned short, 2u>::GetOutput()'collect2: ld returned 1 exit statusmake[2]: *** [test] Error 1make[1]: *** [CMakeFiles/test.dir/all] Error 2make: *** [all] Error 2  importITK is the name of the class I created. In main() funtion, I just invoked some member functions of the class importITK. 
Thanks a lot.

Dear all: I wrote a class to implement some member functions of itk using Linux. The class declaration is in a flie named by importITK.h, and the class definition is in a file named by importITK.cpp. And I wrote a fuction main() in a file named by test.cxx to invoke that class. I included all needed header files in three files. But something's wrong during liking in main() function: undefined reference to member functions of the class I created.  Here is my CMakeLists.txt: FIND_PACKAGE(ITK)IF(ITK_FOUND)  INCLUDE(${ITK_USE_FILE})ELSE(ITK_FOUND)  MESSAGE(FATAL_ERROR          "ITK not found. Please set ITK_DIR.")ENDIF(ITK_FOUND)ADD_EXECUTABLE(test test.cxx importITK.cpp)TARGET_LINK_LIBRARIES(test ITKCommon ITKBasicFilters ITKIO)  I think maybe something's wrong about the CmakeLists.txt I wrote. Thanks a lot.
