Linux Unix C 中的curses庫——curses.h

打算在Linux下用curses.h寫一個圖形界面，結果發現

hello.c:1: fatal error: curses.h: No such file or directory

上網搜索了一下，才發現是少安裝了curses庫

於是在新得立查找libncurses5-dev，點擊應用

寫了一個小程序

#include <curses.h>

int main()
{
    initscr();

    clear();
    move(10, 20);
    addstr("Hello world");   
    move(LINES-1, 0);
    refresh();
    getch();
    endwin();

    return 0;
}

在終端輸入

gcc -o hello hello.c  -Incurses

發現如下錯誤
