I need help with a build of mysql connector 8 test code which fails with symbols not found for architecture x86-64.

This is the code that is to be compiled:

#include <iostream>
#include <mysqlx/xdevapi.h>

using namespace mysqlx;

string usr = "root";
string pwd = “password”;

int main()
{
Session mySession(SessionOption::HOST, "localhost",
SessionOption::PORT, 33060,
SessionOption::USER, usr,
SessionOption::PWD, pwd);

return 0;
}



The following is the output from the build console:

From the looks of this output it seems that there are 10 undefined symbols. Can anybody help interpret this output?

With Thanks
