c - 错误原因及解决方法 -"undefined reference to ` newwin' "?

Question

我正在编译一个在 shell 上创建窗口的程序。当我编译时，我得到类似

的错误

test.c:(.text+0x25): undefined reference to `newwin'
test.c:(.text+0x73): undefined reference to `wborder'
test.c:(.text+0xb6): undefined reference to `mvwprintw'
..
..

我的功能之一是

WINDOW *f_top, *f_bottom;
WINDOW *create_window(int n, int d, char *t){
        WINDOW *frame;
        WINDOW *w;
        frame = newwin(n, COLS, d, 0);
        box(frame,0,0);
        mvwprintw(frame,0,COLS/2-strlen(t)/2,t);
        wrefresh(frame);
        w = newwin(n-2, COLS-2, d+1, 1);
        idlok(w, TRUE);
        scrollok(w, TRUE);
        wclear(w);
        wrefresh(w);
        return w;
}

您需要链接 curses 库。函数在那里定义。

尝试

gcc ... test.c ... -lcurses ...

或者也许

gcc ... test.c ... -lncurses ...
