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
