apue.h头文件

   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、然后再进入apue.2e目录下的std目录，打开linux.mk，将里面的nawk全部替换为awk，可以使用这个命令 ：%s/nawk/awk/g 

   4、把 /home/limeng/apue.2e/inlcude目录下的 apue.h 文件最后添加一行 #include "error.c",将该文件拷贝到/usr/include 目录中。

   5、把 /home/limeng/apue.2e/lib目录下的 error.c 文件第一行 #include "apue.h"注释掉或者删除,也将该文件拷贝到/usr/include 目录中。

   6、编译成功。

   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。

apue.h内容如下：
