linux 下ORCLE OCCI例子运行错误！！！！请帮帮忙啊！

   我在LINUX下没安装数据库，但我安装了oracle-instantclient-basic-10.2.0.3-1.i386.rpm就是客户端，我配置了环境变量LD_LIBRARY_PATH=$/usr/instantclient_10_1/lib下，echo也是对的。然后我有下了oracle-instantclient-devel-10.2.0.4-1.i386.zip就是SDK，里面是include和demo。
我编译demo的时错误是：[root@localhost demo1]# g++ -I/root/oraclesdk/sdk/include -L/usr/instantclient_10_1/lib -L/usr/instantclient_10_1/lib/libocci.so.10.1  -o occidml  occidml.cpp

还是错。各位大哥大姐帮帮忙啊！小弟感激不尽啊！！！
