Building a TCL package of ITK

Is it possible to generate a TCL package of ITK using SimpleITK?

Yes, it is possible to generate a TCL package using SimpleITK. You will need to build SimpleITK and set the CMake WRAP_TCL flag to ON (if on commandline -DWRAP_TCL=ON). Obviously requires a TCL installation on the build system so that CMake will find it and set all the required paths correctly.

Thank you for your answer.
With WRAP_TCL I have gotten a single executable file, a TCL command line application. But I’m locking for a TCL package I can load dynamically at a general TCL application. Additionally I need to have it compatible with VTK 5.10. I think I have to build ITK 4 for it, where the ITK in SimpleITK requires VTK8 for VTKGlue.

It looks like the code to make the TCL library a loadable module was commented out some time ago:

github.com

SimpleITK/SimpleITK/blob/3d4b0145e66c3b05a6a75d57ce4c6ac2462da5f5/Wrapping/Tcl/CMakeLists.txt#L19-L24

    
      
          #  SWIG_add_module ( SimpleITKTcl tcl SimpleITK.i SimpleITKTCL_wrap.cxx )
          #  target_link_libraries ( ${SWIG_MODULE_SimpleITKTcl_TARGET_NAME} ${SimpleITK_LIBRARIES} )
          #  sitk_target_link_libraries_with_dynamic_lookup( ${SWIG_MODULE_SimpleITKTcl_TARGET_NAME} ${TCL_LIBRARY} )
          #  set_source_files_properties(${swig_generated_file_fullname}  PROPERTIES COMPILE_FLAGS "-w")
          #  add_executable ( SimpleITKTclsh ${swig_generated_file_fullname} )
          #  target_link_libraries ( SimpleITKTclsh ${SimpleITK_LIBRARIES} ${TCL_LIBRARY})

SimpleITK does not use the ITKVTK module, so there is not compatibility issues with VTK since SimpleITK does not use it.
