Autoconf version 2.68 or higher is required

今天同事在安装php的redis扩展时，使用phpize报错，

 

 当前系统环境Centos7.7,

内网IP：192.168.80.61

PHP版本：7.3.18

redis扩展版本；4.2.0

 

[root@centos7 redis-4.2.0]# /usr/local/php/bin/phpize

Configuring for:

PHP Api Version:         20180731

Zend Module Api No:      20180731

Zend Extension Api No:   320180731

configure.ac:3: error: Autoconf version 2.68 or higher is required

configure.ac:3: the top level

autom4te: /usr/local/bin/m4 failed with exit status: 63

[root@centos7 redis-4.2.0]#

 

这种问题在Centos6.9上经常遇到，升级autoconf版本到2.69即可。

 

先卸载系统自带的autoconf，再安装一遍autoconf，

yum remove autoconf

yum安装autoconf,会自动安装m4依赖；手动下载安装autoconf，m4也可以；

yum install -y autoconf

 

检查2.69是否安装成功，

/usr/bin/autoconf -V

[root@centos7 ~]# /usr/bin/autoconf -V

 再次使用/usr/local/php/bin/phpize，还是报同样的错误；

 降低PHP版本，重新解压redis源码包，依然报此错误；

在另外一台环境完全相同的服务器192.168.80.64上，安装同一版本的PHP和redis扩展，一路顺畅；

autoconf 2.69明明安装成功了，phpize就是装瞎看不见，挺郁闷....

 

晚上使用strace跟踪phpize，对比，

strace /usr/local/php/bin/phpize，

 

如下图：

左边是192.168.80.61，phpize报错，

右边是192.168.80.64，phpize正常，

 

看到这里就很明显了，左边的phpize使用的是/usr/local/bin/autoconf, 不是我们升级成功的2.69 /usr/bin/autoconf,

只删除/usr/local/bin/autoconf还不够，因为phpize还加载了/usr/local/bin/下的autoheader等，所以需要全部删除auto相关的安装

rm -rf auto* ifnames
