apue学习记录——配置apue.3e，实现P4‘ls例子

 #include"apue.h"
 #include<dirent.h>

 int main(int argc,char *argv[])
 {
     DIR            *dp;
     struct dirent        *dirp;

     )
         err_quit("usage:ls directroy_name:");
     ])) == NULL)
         err_sys(]);
     while ((dirp = readdir(dp)) != NULL)
         printf("%s\n",dirp->d_name);

     closedir(dp);
     exit();
 } 

编译成功就是因为没有这个apue.h 头文件

需要去http://www.apuebook.com/code3e.html

用tar 指令解压到自己准备放的目录

$sudo apt-get install libbsd-dev

make

会出现问题：

:(.text+0x20): undefined reference to `err_quit' 
:(.text+0x5b): undefined reference to `err_sys'

gcc时 加上gcc XX.c -lpaue

完毕
