#./configure --prefix……检查编辑环境时出现：
checking for APR... no
configure: error: APR not found .  Please read the documentation.

可以用./configure –help | grep apr 查看帮助。
--with-included-apr     Use bundled copies of APR/APR-Util
--with-apr=PATH         prefix for installed APR or the full path to apr-config
--with-apr-util=PATH    prefix for installed APU or the full path to
安装APR(Apache Portable Runtime )
[root@localhost ~]# cd /tmp/52lamp/ //源码存放位置
[root@localhost 52lamp]# tar -zxvf apr-1.4.2.tar.gz //unzip -o apr-1.4.2.zip
[root@localhost 52lamp]# cd apr-1.4.2
[root@localhost apr-1.4.2]# ./configure
[root@localhost apr-1.4.2]# make
[root@localhost apr-1.4.2]# make install

再次检查编译环境出现
checking for APR-util... no
configure: error: APR-util not found .  Please read the documentation.

[root@localhost  httpd-2.2.16]# ./configure –help | grep apr-util
--with-apr-util=PATH    prefix for installed APU or the full path to

[root@localhost 52lamp]# tar -zxvf apr-util-1.3.9.tar.gz
[root@localhost 52lamp]# cd apr-util-1.3.9
[root@localhost apr-util-1.3.9]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
[root@localhost apr-util-1.3.9]# make
[root@localhost apr-util-1.3.9]# make install

./configure仍提示APR-util not found，增加--with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util后出现
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/ 

[root@localhost  httpd-2.2.16]# ./configure –help | grep pcre
--with-pcre=PATH        Use external PCRE library

[root@localhost 52lamp]# unzip -o pcre-8.10.zip
[root@localhost 52lamp]# cd pcre-8.10
[root@localhost cd pcre-8.10]# ./configure --prefix=/usr/local/pcre
[root@localhost cd pcre-8.10]# make
[root@localhost cd pcre-8.10]# make install

继续安装Apache/httpd，./configure 时加上参数 --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre，这个问题就解决了。
