想要使用，還要進行下面操作，完成相關配置.

在http://www.apuebook.com/下載src.tar.gz源代碼的壓縮包。

1、解壓至/home/user/目錄下

2、修改 Make.defines.linux中的WKDIR=/home/xxx/apue.2e，為WKDIR=/home/user/apue.2e

3、返回至apue.2e目錄下面，修改linux.mk，將裡面的nawk全部改為awk，可以使用這個命令 ：%s/nawk/awk/g

4、make

5、將/home/user/apue.2e/include/apue.h和/home/user/apue.2e/lib/error.c復制到/usr/include目錄下
