打算在Linux下用curses.h寫一個圖形界面，結(jié)果發(fā)現(xiàn)

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

上網(wǎng)搜索了一下，才發(fā)現(xiàn)是少安裝了curses庫

于是在新得立查找libncurses5-dev，點(diǎn)擊應(yīng)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(fā)現(xiàn)如下錯誤

hello.c:(.text+0x91): undefined reference to `endwin'
collect2: ld returned 1 exit status
在終端輸入

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

編譯成功！
