编译apache报APR not found

系统环境：

[vagrant@rs-2 download]$ cat /etc/redhat-release 

CentOS release 5.6 (Final)

[vagrant@rs-2 download]$ uname -a

Linux rs-2 2.6.18-238.el5 #1 SMP Thu Jan 13 15:51:15 EST 2011 x86_64 x86_64 x86_64 GNU/Linux

编译apache 2.4.9

[vagrant@rs-1 httpd-2.4.9]$ ./configure --prefix=/usr/local/apache

编译apache, 遇到下面错误

configure: error: APR not found.  Please read the documentation.

configure: error: APR-util not found.  Please read the documentation.

去http://archive.apache.org/dist/apr/去下载相关包

[vagrant@rs-1 download]$ wget http://archive.apache.org/dist/apr/apr-1.5.1.tar.gz

[vagrant@rs-1 download]$ wget http://archive.apache.org/dist/apr/apr-util-1.5.3.tar.gz

安装 apr 包

[vagrant@rs-1 apr-1.5.1]$ ./configure --prefix=/usr/local/apr

[vagrant@rs-1 apr-1.5.1]$ make

[vagrant@rs-1 apr-1.5.1]$ sudo make install

安装apr-util

[vagrant@rs-1 apr-util-1.5.3]$ ./configure
--prefix=/usr/local/apr-util -with-apr=/usr/local/apr/bin/apr-1-config 

[vagrant@rs-1 apr-util-1.5.3]$ make 

[vagrant@rs-1 apr-util-1.5.3]$ sudo make install

最后，编译apache时候加上

--with-apr=/usr/local/apr \

--with-apr-util=/usr/local/apr-util/

[vagrant@rs-1 httpd-2.4.9]$ ./configure
--prefix=/usr/local/apache --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/
