FLTK library. And when i type "g++ -o scratch scratch.c++". it gives the
error:
/usr/bin/ld: Undefined symbols:
Fl::run()
Fl_Widget::Fl_Widget(int, int, int, int, char const*)
Fl_Widget::~Fl_Widget()
Fl_Window::show()
Fl_Window::Fl_Window(int, int, char const*)
Fl_Window::~Fl_Window()
vtable for Fl_Box
collect2: ld returned 1 exit status

tell linker where to find the library.
use

发帖数: 2024 | 4 as thrust told you, you need to link your F**k library.
such like:
g++ -o scratch scratch.c++ -LF**klibrary | w*****j
发帖数: 49 | 5 Hi,I used -lfltk and it sort of change the error message:
Undefined symbols:
_AECountItems
_AECreateDesc
etc.
Am I supposed to link to another library?
