在linux下安裝php時，（我安裝的時5.2.6）phptar.gz壓縮包解壓縮之後。
在分配路徑和關聯擴展包時遇到錯誤如下：
--------------------------------------------------------
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)
---------------------------------------------------
解決步驟：
1、根據不能run apxs 。cd 到apache的bin目錄下運行./apxs 運行結果
----------------------------------------------------
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”關鍵字
在第一個行 ：#!/replace/with/path/to/perl/interpreter -w
根據perl的安裝目錄 /usr/bin/perl
修改爲：#! /usr/bin/perl -w
3、運行第一步。或者直接 ./configure ^^^^^
問題解決
configure 代碼如下：
./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
