请教 Linux下编写occi程序出错 undefined reference to `oracle::occi::Environment

blazingsnow

环境是 LinuxAS4
gcc 版本 : 3.4.4
occi版本： occi_gcc343_102030.tar.gz

很简单的一个程序[occi10.cpp]，如下：
#include <string>
#include <iostream>
#include <occi.h>
using namespace oracle:cci;
using namespace std;


int main(int argc, char* argv[])
{
        printf("Connect to Oracle\n";

        string  sUser     = "USER";
        string  sPassword = "ASSWORD";
        string  sDB       = "DATABASE";
        Environment *env  = Environment::createEnvironment (Environment:EFAULT);
        Connection  *conn = env->createConnection (sUser, sPassword, sDB);

        Statement * stmt = conn->createStatement("SELECT DATA1, DATA2 FROM TEST_TABLE";
      
        ResultSet *rset = stmt->executeQuery();

        while (rset->next())
        {
                cout << "DATA1:" << rset->getString (1) ;
                cout << "DATA2:" << rset->getString (2) << endl;

        }
        stmt->closeResultSet (rset);
        conn->terminateStatement (stmt);

        env->terminateConnection (conn);
        Environment::terminateEnvironment (env);
        return true;
}

编译的命令如下:
g++ -L /usr/lib/oracle/10.2.0.3/client/lib  -I /usr/include/oracle/10.2.0.3/client/  -o occi10.o -c occi10.cpp
然后：
g++ -o occi10 occi10.o

之后产生错误：
occi10.o(.text+0x23f): 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*))'
occi10.o(.text+0x51e): In function `main':
: undefined reference to `oracle:cci::Environment::terminateEnvironment(oracle:cci::Environment*)'
collect2: ld returned 1 exit status




期望高手指点，谢谢！

我想你应该在连接时加上occi的库，如：
g++ -o occi10 -L_<1>_ -l_<2>_ occi10.o
位置<1> occi库文件所在的路径
位置<2> occi库文件
