问题：

[root@monitor pdo_mysql]# phpize 

Configuring for:  PHP Api Version: 20090626  Zend Module Api No: 20090626  Zend Extension Api No: 220090626  config.m4:138: warning: AC_CACHE_VAL(pdo_inc_path, ...): suspicious cache-id, must contain _cv_ to be cached  ../../lib/autoconf/general.m4:1974: AC_CACHE_VAL is expanded from...  ../../lib/autoconf/general.m4:1994: AC_CACHE_CHECK is expanded from...  aclocal.m4:2748: PHP_CHECK_PDO_INCLUDES is expanded from...  config.m4:138: the top level  config.m4:138: warning: AC_CACHE_VAL(pdo_inc_path, ...): suspicious cache-id, must contain _cv_ to be cached  ../../lib/autoconf/general.m4:1974: AC_CACHE_VAL is expanded from...  ../../lib/autoconf/general.m4:1994: AC_CACHE_CHECK is expanded from...  aclocal.m4:2748: PHP_CHECK_PDO_INCLUDES is expanded from...  config.m4:138: the top level

解决方法：

autoconf版本太高造成的,我的办法是安装autoconf 2.13

redhat类系统运行如下命令

yum install autoconf213.noarch 

export PHP_AUTOCONF=/usr/bin/autoconf-2.13  export PHP_AUTOHEADER=/usr/bin/autoheader-2.13

64位环境下

configure: error: libjpeg.(a|so) not found.

或者 configure: error: *.(a|so) not found.

这些库已经安装了但还报错

在configure 时加参数 –with-libdir=lib64
