安装软件包
dnf install epel-release # 后面安装libbsd-devel需要用到
dnf groupinstall "Development Tools"
下载APUE相关源码
wget http://www.apuebook.com/src.3e.tar.gz
开始编译
tar -xf src.3e.tar.gz
cd apue.3e/
make
报错解决
报错一：

错误三: 缺少bsd库
安装相应的库
dnf install libbsd-devel
编译完成后复制头文件和库文件到相应的系统目录中
cp /root/apue.3e/include/apue.h /usr/include/
cp /root/apue.3e/lib/libapue.a /usr/lib/
