since last 3 days I am trying to run an sample Oracle db connectivity I'm my Yosemite Mac using g++(inside eclipse). I have gone through all similar questions in this side, but sadly nothing works for me. Instead, I have tried with both the 32 and 64 bit of instant client library of Oracle, but still the error.

Updating the output from my PC. I have linked the Library(as advised by some experts) but still the same.

Please find below the code

#include<stdio.h>
#include<iostream>
#include <occi.h>
using namespace oracle::occi;
using namespace std;

int main (int argc, char *argv[]){
    const std::string userName = "SCOTT";
    const std::string password = "tiger";
    const std::string connectString = "192.168.69.141:1521/orcl.test.com";
    Environment *env = Environment::createEnvironment();

    Connection *conn = env->createConnection( userName, password, connectString);
    Statement *stmt = conn->createStatement( "SELECT ename from emp");
    ResultSet *rs = stmt->executeQuery(); rs->next();
    string b = rs->getString(1);
    cout << "Name" << b <<endl;
    stmt->closeResultSet(rs); conn->terminateStatement(stmt); env->terminateConnection(conn);
    Environment::terminateEnvironment(env);
    return 0;
}

and the output is 

g++ -v -L/Users/Shared/instantclient_11_2-4 -o "TestCPlusPlus"  ./src/CTimeSpan.o ./src/TCRequestProc.o ./src/TCTransactionQueue.o ./src/TestCPlusPlus.o ./src/TestOra.o

  • You're not linking with the libraries. – molbdnilo Aug 26 '15 at 09:14
  • Not at all a duplicate question...I have searched everywhere...100s of pages....linking library etc....nut not success...even with RedHat Linux also. .....its not working....now I know why windows are better.... – Tapas Aug 28 '15 at 10:39
  • It's clear from your command line that you're not linking with the instant client library. The capital "-L" only specifies a directory to search for libraries in, not which libraries to search for. – molbdnilo Aug 28 '15 at 11:28
