系统环境：
[root@Web-Lamp ~]# cat /etc/redhat-release CentOS release 6.6 (Final) [root@Web-Lamp ~]# uname -r 2.6.32-504.el6.x86_64
Apache安装版本：
[root@Web-Lamp tools]# ll -rw-r--r-- 1 root root 6784016 Jul 16 2014 httpd-2.4.9.tar.gz
今日编译apache时出错：
#./configure --prefix……检查编辑环境时出现： checking for APR... no configure: error: APR not found . Please read the documentation
解决办法：
1.下载所需软件包：
wget http://archive.apache.org/dist/apr/apr-1.4.5.tar.gz wget http://archive.apache.org/dist/apr/apr-util-1.3.12.tar.gz wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.10/pcre-8.10.zip
2.编译安装：
yum remove apr-util-devel apr apr-util-mysql apr-docs apr-devel apr-util apr-util-docs
具体步骤如下:
a:解决apr not found问题>>>>>>
tar -zxf apr-1.4.5.tar.gz cd apr-1.4.5 ./configure --prefix=/usr/local/apr make && make install
b:解决APR-util not found问题>>>>
tar -zxf apr-util-1.3.12.tar.gz cd apr-util-1.3.12 ./configure --prefix=/usr/local/apr-util -with-apr=/usr/local/apr/bin/apr-1-config make && make install
c:解决pcre问题>>>>>>>>>
unzip -o pcre-8.10.zip cd pcre-8.10 ./configure --prefix=/usr/local/pcre make && make install
3.最后编译Apache时加上：
--with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre
成功编译完成~
