[Insight-users] Re: about FLTK

[Luis Ibanez]

Hi Hui,

These errors indicate that you are mixing compilation modes
{Debug/Release/RelWithDebInfo/..} between the multiple
libraries that you are using.

You *MUST* compile all libraries using exactly the same
compilation mode.



What you may want to do at this point is:


   1) Delete the binary directories that you have so far
      (related to your application).

   2) Choose a compilation mode {Debug/Release} and then

   3) Build every one of your libraries using that *SAME*
      compilation  mode.


Please note that recent versions of FLTK (1.1.6 and later) do have a
CMakeLists.txt file. Therefore you can configure them using CMake and
in this way, when you combine multiple libraries, you have better
chances of producing executables with consistent compilation modes.



    Regards,


       Luis
