Centos安装Apache的问题
安装Apache时需要先安装apr, 我下载了1.4.6版本,make的时候出现错误:

google之后发现有些人是说libtool的版本问题, 于是卸载掉旧的libtool 1.5, 装一个2.4.2版本,结果./configure的时候出现这样的问题:
checking whether accepts -g... no
checking for gccgo... no
checking for gcj... no
checking for windres... no
checking whether make supports order-only prerequisites... yes
configure: creating ./config.status
config.status: creating Makefile
config.status: creating config.h
config.status: config.h is unchanged
config.status: executing tests/atconfig commands
config.status: executing depfiles commands
config.status: executing libtool commands

各位大虾，如何安装apr



------解决方案--------------------
apr-1.4.6.tar.gz和apr-util-1.4.1.tar.gz都要有，看看Apaache官网安装说明，链接：http://httpd.apache.org/docs/2.4/install.html

Make sure you have APR and APR-Util already installed on your system. 
If you don't, or prefer to not use the system-provided versions, 
download the latest versions of both APR and APR-Util from Apache APR, 
unpack them into ./srclib/apr and ./srclib/apr-util 
(be sure the domain names do not have version numbers; for example, the APR distribution must be under ./srclib/apr/) 
and use ./configure's --with-included-apr option. 
On some platforms, you may have to install the corresponding -dev packages to allow httpd to build against your installed copy of APR and APR-Util.
