Re: fltk compilation error


I am unable to determince what the error is, not knowing anything about gcc, fltk or fltk-config

the following command produces a gui executable (at least for this trivial example)
which prints "Hello World" to the console when Open is selected from the File menu.


gcc test.cxx -lfltk -lstdc++

Please advise.
