Re: [Dev-C++] Beginner : trouble with FLTK ...

[Per W. <pw...@ia...>]

It isn't enough to add an include directory - it is only where the
compiler should locate the include files referenced in your source.

You also have to add the needed libraries to your linker options. FLTK is
no exception. Whenever you use new libraries, you must add the libraries
to the linker options - note that order matters, i.e. a library that
references other libraries should be listed earlier on the command line.
