An error is reported when compiling apr-util in Linux. linuxapr-util
Preface

Apache 2.4 and later versions do not have their own APR Library (Apache Portable Runtime, Apache can be transplanted to the Runtime Library). Therefore, 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-iconv.

 

Body

After downloading the apr-util package from the official website and decompressing the package and executing make compilation, the following error is returned:

Generally, the xml parser is missing. After checking the network information, find the solution. yum installsExpat-develPackage:

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