Linux Unix C 中的curses库——curses.h

打算在Linux下用curses.h写一个图形界面，结果发现hello.c:1: fatal error: curses.h: No such file or directory上网搜索了一下，才发现是少安装了curses库于是在新得立查找libncurses5-dev，点击应用写了一个小程序#include <curses.h>int main（）
{
    initscr（）;    clear（）;
    move（10, 20）;
    addstr（"Hello world"）;
    move（LINES-1, 0）;
    refresh（）;
    getch（）;
    endwin（）;    return 0;
}在终端输入gcc -o hello hello.c -Incurses发现如下错误/tmp/ccsmlmYV.o: In function `main":

在终端输入gcc hello.c -o hello -I/usr/include -L/usr/lib -lncurses编译成功！
