CentOS安装apr-util时报错:xml/apr_xml.c:35:19: fatal error: expat.h: No such file or directory

在CentOS 7上安装apr-util，安装apr是正常的，安装apr-util时报错：

[root@localhost apr-util-1.6.1]# make
make[1]: Entering directory `/home/cc/download/apr-util-1.6.1'

查了下，只需要安装依赖expat-devel即可。执行命令：

yum install expat-devel

重新make安装apr-util，执行成功。
