[Insight-users] Re: FLTK and ITK on Mac OS X: Fl::error

[Phillip Cheng]

Hi Luis,

Your paranoid thought was correct!  I fixed the problem by rearranging 
the last few lines of FindFLTK.cmake from

IF(FLTK_FOUND)
   SET(FLTK_LIBRARIES ${FLTK_BASE_LIBRARY} ${FLTK_GL_LIBRARY}
                      ${FLTK_FORMS_LIBRARY} ${FLTK_IMAGES_LIBRARY}
                      ${FLTK_PLATFORM_DEPENDENT_LIBS})
ENDIF(FLTK_FOUND)

to

IF(FLTK_FOUND)
   SET(FLTK_LIBRARIES ${FLTK_PLATFORM_DEPENDENT_LIBS}
                      ${FLTK_BASE_LIBRARY} ${FLTK_GL_LIBRARY}
                      ${FLTK_FORMS_LIBRARY} ${FLTK_IMAGES_LIBRARY})
ENDIF(FLTK_FOUND)

And mirabile dictu, it just works!  I'll leave it to the gurus to 
fathom why.

Now all I have to do is apply the 'Rez Carbon.r' fix.  Perhaps someday 
this can be made automatic?

By the way, for clarification, there was a typo in your previous 
message.  The declaration in Fl/Fl.h is
static void (*error)(const char*, ...);

I am using fltk-1.1.3, built on the Mac.

Thanks again,

Phillip
