Please don't post directly to fltk.bugs, this is reserved for FLTK's
bug tracking system (www.fltk.org/str.php). Your post is more like a
general user question, so you should use fltk.general for this.
Anyway, trying to answer your question: Either you didn't include
-lfltk_images (the image libraries), or (ISTR) you could try to switch
the compiler settings from clang to gcc/g++.
If this doesn't help, please ask again in fltk.general.
