[Insight-users] accessing and building Itk applications

[Luis Ibanez]

Hi Zein,

1) FLTK will add this "d" and the end of libraries
     when you build in debug mode.

     You have to build everything (FLTK+ITK+VTK) for
     debug or everything for release.

     The selection between both building modes is
     made the "Build" menu.

2)  I strongly recomend you to use CMake to configure
     your project. You could do it without CMake but
     will simply be a painful and slow process.
     With a CMakeLists.txt file, it will be much simpler.
     When you write the CMakeLists.txt file, you have
     the command TARGET_LINK_LIBRARIES, this is where
     you add the list of libraries to link with.

     Here is below a skeleton of a typical CMakeLists.txt
     file

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 the executable with our source file.
ADD_EXECUTABLE(MyExecutable
sourcefile1.cxx
sourcefile2.cxx
sourcefile3.cxx
)

TARGET_LINK_LIBRARIES( MyExecutable
   ITKAlgorithms
   ITKBasicFilters
   ITKNumerics
   VXLNumerics
   ITKIO
   ITKCommon
   )


3) for fltkgld.lib, just add this library to the
    list above in TARGET_LINK_LIBRARIES.



Please let us know if you have further
questions.


Thanks


   Luis

application some other way? or build FLTK some other way? or both?

PLEEEEEEASE do not ignore my last message regrding this problem.
