occi编译报错，请大家帮忙看看是什么原因。谢谢

环境：aix53、gcc4.2、oralce10g
编译一个简单的demo时报错
ld: 0711-317 ERROR: Undefined symbol: .oracle:cci::Environment::createEnvironment(oracle:cci::Environment::Mode, void*, void* (*)(void*, unsigned long), void* (*)(void*, void*, unsigned long), void (*)(void*, void*))
ld: 0711-317 ERROR: Undefined symbol: .oracle:cci::Environment::terminateEnvironment(oracle:cci::Environment*)
ld: 0711-317 ERROR: Undefined symbol: typeinfo for oracle:cci::SQLException
collect2: ld returned 8 exit status

考虑可能是occi库装的不全，从oracle官方网站下载了一个instantclient_11_2，解压安装后，引入编译还是同样的问题。。。
