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':
hello.c:(.text+0xa): undefined reference to `initscr'
hello.c:(.text+0xf): undefined reference to `stdscr'

hello.c:(.text+0x91): undefined reference to `endwin'
collect2: ld returned 1 exit status
在终端输入

gcc hello.c -o hello -I/usr/include -L/usr/lib -lncurses

编译成功！
