fltk compilation error

[Ken Dibble]

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.
