下载: src.3e.tar.gz http://www.apuebook.com/src.3e.tar.gz
解压: tar xvf src.3e.tar.gz
安装相应库: sudo apt-get install libbsd-dev
进入到apue.3e目录，执行: make
cp ./include/apue.h /usr/include/
cp ./lib/libapue.a /usr/local/lib/
编译时链接到相应库: gcc -o 1-3 1-3.c -lapue

apue.h是作者自己写的一个文件，包含了常用的头文件，系统不自带。其中包含了常用的头文件，以及出错处理函数的定义。使用起来确实很方便。

apue.h内容如下：

ifndef _APUE_H

define _APUE_H

define _XOPEN_SOURCE 600 /* Single UNIX Specification, Version 3 */

include <sys/types.h> /* some systems still require this */

include <sys/stat.h>

ifndef TIOCGWINSZ

endif

include <stdio.h> /* for convenience */

include <string.h> /* for convenience */

include <unistd.h> /* for convenience */

include <signal.h> /* for SIG_ERR */

想要使用，还要进行下面操作，完成相关配置.

在http://www.apuebook.com/下载src.tar.gz源代码的压缩包。

1、解压至/home/user/目录下

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

3、返回至apue.2e目录下面，修改linux.mk，将里面的nawk全部改为awk，可以使用这个命令 ：%s/nawk/awk/g

4、make

5、将/home/user/apue.2e/include/apue.h和/home/user/apue.2e/lib/error.c复制到/usr/include目录下

然后就可以方便的使用apue.h编译《unix高级环境编程》的的程序了
