I tried to compile the following code:

#include <ncurses.h>

int main()
{
initscr();
printw("Hello World!!!");
refresh();
getch();
endwin();

return (0);
}

and got the following error messages:

unbinder@Julian:~$ g++ -o nimrl ~/stories/code/nimrl.cpp
/home/unbinder/stories/code/nimrl.cpp:12:2: warning: no newline at end

Is there a newsgroup dedicated to ncurses? I couldn't find one.

Thank you, Filip & Sheep. I will remember your kindness when i know
what i'm doing and newbies start asking me similarly obnoxious
questions

You forgot to link it with curses library. Header files in C++ are not
like "import" or "using" from other languages, you still have to show
the linker the right object file where the curses functions can be
found. I have not programmed under Linux curses in ages, but I guess
it would be -lncurses.
