    Yet another clear screen thread :D

    I am working on a program, and I wanted to clear the screen - (yes I read the faq, and yes I searched the boards) - I have come up with a suitable method of clearing the screen (I don't need it to be portable, as the program is strictly for my own use). Anyway, I tried using Hammer's solution from the faq:

    Code:
    #include <curses.h> 
    
    void clrscr(void)
    {
        static int init;
    
        if (init == 0)
        {
            initscr();
            init = 1;
        }
    
        clear();
        refresh();
    }
    But the compiler (gcc) fed me this:

    /tmp/ccSsrP07.o: In function `clrscr':
    87: undefined reference to `initscr'
    91: undefined reference to `stdscr'
    91: undefined reference to `wclear'
    92: undefined reference to `stdscr'
    92: undefined reference to `wrefresh'
    collect2: ld returned 1 exit status
    So then I read about the clear() function (?) as well as werase() and so from the man pages, and thought that they looked like my solution, but I got this when I used clear():

    /tmp/ccy5cjO5.o: In function `primary_menu':
    53: undefined reference to `stdscr'
    53: undefined reference to `wclear'
    collect2: ld returned 1 exit status
    I don't suppose somebody could explain all of this to me, as to why the two functions I tried would not work?

    i havent done curses but:

    gcc -o test test.c -lcurses

    should work. that tells the compiler to link in the curses library (if it's installed)
