linux连接oracle问题

我的代码：
#include "occi.h"
#include <iostream>

using namespace oracle:cci;
using namespace std;

int main()
{
        Environment *env;
    Connection *con;
    env = Enviroment::createEnvironment(Environment:EFAULT);
    cout << "**" << endl;
    return 0;
}

g++ -Wno-deprecated -fPIC -march=i486 -L/opt/oracle/product/9.2.0/lib -L/opt/oracle/product/9.2.0/rdbms/lib  -I/opt/oracle/product/9.2.0
/rdbms/public -I/opt/oracle/product/9.2.0/rdbms/demo test.cpp -c
编译可以过

g++ -Wno-deprecated -fPIC -march=i486 -L/opt/oracle/product/9.2.0/lib -L/opt/oracle/product/9.2.0/rdbms/lib -locci9 -I/opt/orac
le/product/9.2.0/rdbms/public -I/opt/oracle/product/9.2.0/rdbms/demo -o test test.cpp
编译加连接，报错如下：
/tmp/ccpgfYCI.o(.text+0x2b): In function `main':
: undefined reference to `oracle:cci::Environment::createEnvironment(oracle:cci::Environment::Mode, void*, void* (*)(void*, unsigned int), void* (*)(void*, void*, unsigned int), void (*)(void*, void*))'
collect2: ld returned 1 exit status

请高手指点，谢谢！！！！
