編譯 php-memcache 擴充套件時提示Cannot find autoconf

下載memcache擴充套件 http://pecl.php.net/package/memcache ,到 /usr/local/src目錄下並解壓

[[email protected] src]# tar zxf memcache-2.2.7.tgz
[[email protected] src]# cd memcache-2.2.7
[[email protected] memcache-2.2.7]# ls
config9.m4  CREDITS      memcache_consistent_hash.c  memcache_queue.c    memcache_standard_hash.c
config.m4   example.php  memcache.dsp                memcache_queue.h    php_memcache.h
config.w32  memcache.c   memcache.php                memcache_session.c  README

根據當前的 php 版本動態的建立擴充套件的 configure 檔案

[[email protected] memcache-2.2.7]# /usr/local/php7/bin/phpize 
Configuring for:
PHP Api Version:         20180731
Zend Module Api No:      20180731
Zend Extension Api No:   320180731
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.

錯誤提示  Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable. Then, rerun this script.

缺少autoconf,通過yum安裝 m4 和 autoconf

[[email protected] memcache-2.2.7]# yum install -y m4

[[email protected] memcache-2.2.7]# yum install
-y autoconf

再次建立configure檔案
