PHP动态编译出现Cannot find autoconf
在安装完PHP后,想动态编译PHP的memcache扩展库
cd memcache-2.2.5/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
但是执行/usr/local/webserver/php/bin/phpize时出现错误:

Configuring for: PHP Api Version:         20041225 Zend Module Api No:      20060613 Zend Extension Api No:   220060519 Cannot find autoconf. Please check your autoconf installation and the  $PHP_AUTOCONF  environment variable is set correctly and then rerun this script.

   
在网上搜索一通,发现这个问题提的人还挺多,摘了一段下来:
# wget http://ftp.gnu.org/gnu/m4/m4-1.4.9.tar.gz
# tar -zvxf m4-1.4.9.tar.gz
# cd m4-1.4.9/
# ./configure && make && make install
# cd ../
# wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.62.tar.gz
# tar -zvxf autoconf-2.62.tar.gz
# cd autoconf-2.62/
# ./configure && make && make install
