将 ncurses 静态链接到程序 [英] Statically link ncurses to program

问题描述

我在将 ncurses 静态链接到我的一个程序时遇到了一些问题

I'm having some problems statically linking ncurses to one of my programs

这是一个非常简单的示例程序:

Here's a really simple sample program:

#include<ncurses.h>


int main(){

    initscr();
    printw("Hello world
");
    refresh();
    getch();
    endwin();
    return 0;
}

当我用

gcc -static -lncurses hello_curses.c -o curses

我收到以下错误:

/tmp/ccwHJ6o1.o: In function `main':
curses_hello.c:(.text+0x5): undefined reference to `initscr'
curses_hello.c:(.text+0x14): undefined reference to `printw'
curses_hello.c:(.text+0x1b): undefined reference to `stdscr'
curses_hello.c:(.text+0x20): undefined reference to `wrefresh'
curses_hello.c:(.text+0x27): undefined reference to `stdscr'
curses_hello.c:(.text+0x2c): undefined reference to `wgetch'
curses_hello.c:(.text+0x31): undefined reference to `endwin'
collect2: ld returned 1 exit status

我有点困惑为什么这不起作用.我在这里错过了什么?

I'm a little confused why this isn't working. What am I missing here?

推荐答案

需要在命令行末尾传递-l选项:

You need to pass -l options at the end of the command line:

gcc -static hello_curses.c -o curses -lncurses

当编译器遇到 -lfoo 时，它会从 foo 中链接上一个文件已请求的所有符号.如果你把 -lfoo 放在开头，还没有任何符号被请求，所以没有符号被链接.

When the compiler encounters -lfoo, it links in all the symbols from foo that have been requested by a previous file. If you put -lfoo at the beginning, no symbol has been requested yet, so no symbol gets linked.
