You don't say what host platform you are on, or what toolchain you are using. I'm guessing (from the path spearators) that's it a *nix of some sort, and the diagnostics look like gcc... Anyway, regardless of that, it looks very much like you forgot to tell the linker to link against the fltk lib (that would be libfltk.a assuming I guessed your host system correctly!) when linking your compiled object. For a single-file project then just doing fltk-config --compile my_file.cxx Will probably do it. For anything more complex, well, Makefiles are good....
