Foreword

The version after Apache 2.4 no longer comes with its own APR Library (APACHE portable runtime), so you need to manually download and install the APR library before installing Apache

The complete APR actually contains three dependent packages: Apr, APR util, and APR icon v

Text

The APR util package is downloaded on the official website and executed after decompression   make   During compilation, the following errors are reported:

Generally speaking, there is a lack of XML parser. After consulting the network data, we found a solution. Just install a expat devel package using Yum:

[root@mingc apr-util-1.6.0]# yum -y install expat-devel
