在linux下安装php时，（我安装的时5.2.6）phptar.gz压缩包解压缩之后。
在分配路径和关联扩展包时遇到错误如下：
--------------------------------------------------------
Sorry, I cannot run apxs. Possible reasons follow:
1. Perl is not installed
2. apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs
3. Apache was not built using --enable-so (the apxs usage page is displayed)
---------------------------------------------------
解决步骤：
1、根据不能run apxs 。cd 到apache的bin目录下运行./apxs 运行结果
----------------------------------------------------
bash: ./apxs: /replace/with/path/to/perl/interpreter: bad interpreter: No such file or directory
---------------------------------------------------------
2、vim apxs文件 找“/replace/with/path/to/perl/interpreter”关键字
在第一个行 ：#!/replace/with/path/to/perl/interpreter -w
根据perl的安装目录 /usr/bin/perl
修改为：#! /usr/bin/perl -w
3、运行第一步。或者直接 ./configure ^^^^^
问题解决
configure 代码如下：
./configure--prefix=/usr/local/php/--with-config-file-path=/usr/local/php/etc/--with-apxs2=/usr/local/apache2/bin/apxs--with-MySQL=/usr/local/mysql/--with-libxml-dir=/usr/local/libxml2/--with-jpeg-dir=/usr/local/jpeg6/--with-freetype-dir=/usr/local/freetype/--with-gd=/usr/local/gd2/--with-mcrypt=/usr/local/libmcrypt/--with-mysqli=/usr/local/mysql/bin/mysql_config--enable-soap--enable-mbstring=all--enable-sockets
