Linux编译apr-util时报错

时间:2017-12-03来源:linux网站 作者:mingc
前言
Apache 2.4 以后的版本不再自带 APR 库(Apache Portable Runtime,Apache 可移植运行库),所以在安装 Apache 之前需要手动下载安装 APR 库。
完整的 APR 实际上包含了三个依赖包:apr、apr-util 以及 apr-iconv。
 
正文
在官网http://apr.apache.org/下载了 apr-util 包,解压后执行 make 编译时,报错如下:

大致是说缺少了 xml 的解析器。查阅网络资料后找到了解决方案,yum 安装一个 expat-devel 包即可:
[root@mingc apr-util-1.6.0]# yum -y install expat-devel
