[Insight-users] FLTK problem -- still struggling

[Seniha Esen Yuksel]

Hi Julien,

 I compiled ITK with shared libraries turned off, then I compiled the InsightApplications and got the ImageViewer working! Good news!! But then to learn what I was doing wrong, I deleted the InsightApplications and compiled again :(( (bad idea! :-) ) 
 Now I am getting the error:
 
 ./ImageViewer out.mhd
 ./ImageViewer: error while loading shared libraries: libITKFltkImageViewer.so: cannot open shared object file: No such file or directory
 
Then I recompiled the InsightApplications, I tried turning on or off the shared library options, but they didn't work I am getting the same error.
 
 I really hope this will be my last question :)
 Thanks a lot!
 Esen

Happy to see that we are making some progress :)

The error looks like a mis-compilation of ITK or something like that. 
Did you try to recompile ITK?
Are you compiling ITK using shared libraries? Can you try using static 
libraries? (there is an option in CMake)

For the information FLTK 1.1.6 comes with a CMakeLists.txt and you 
should be able to run CMake on it. Then when you configure 
InsightApplications with CMake the FLTK_DIR is the FLTK binary directory 
generated by CMake and CMake should magically find all the FLTK related 
libraries and includes.
