dear fltk progammer by c++ (on linux/ubuntu):
after i install every package and ready to go(compile) some simple fltk
program from Mr. Stroustrup "Programming-Principle and practice usingC++" 4th
ed., chapter 12's first example program(chapter.12.3.cpp
copied from his website,
http://www.stroustrup.com/Programming/
)
I get a lot compile errors, which is really out of novice as me to figure out.
