这种警告导致程序不能运行pdo_oci函数，求救

------解决方案--------------------
未知。。。
------解决方案--------------------
你那个httpd.conf文件中.pdo也要打开，然后再试试
------解决方案--------------------
复制粘贴...应该差不多了.
没装过oci.

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
