今天在CentOS 6.4 x86_64下安装PHP 5.4.7的ldap扩展库时，出现PHP configure: error: Cannot find ldap libraries in /usr/lib错误。这个错误提示在/usr/lib 下找不到相关模块，这是因为64位的linux默认把openldap的so库文件都放在 /usr/lib64 文件夹下。有两个办法解决：将/usr/lib64目录中所有ldap的so库拷贝到/usr/lib目录中，然后重新configure

cp -frp /usr/lib64/libldap* /usr/lib/

在configure的时候，指定--with-libdir=lib64
