libpqxx simple connection to database

(1/1)

itsols:
I'm trying to make my first db program and I've tried this:


--- Code: ---#include <pqxx/pqxx>
#include <iostream>

using namespace std;
int main()
{

    pqxx::connection MyConn ("dbname=dbESM user=postgres");
    //pqxx::work txn(MyConn);


    cout << "Hello world!" << endl;

    return 0;
}

--- End code ---
But I get the following error on hitting F9:

--- Quote ---/usr/include/pqxx/connection.hxx|87|undefined reference to pqxx::connectionpolicy::connectionpolicy(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)

--- End quote ---
I'm not sure how to get about this. Any help would be really appreciated.

I'm using Ubuntu 12.04.
Thanks!

Thanks for the inputs. I found the instructions useful.

I also had some good instructions from another site and that was really helpful in solving the issue. Here's the link: http://stackoverflow.com/questions/17386598/simple-c-program-using-pqxx-postgres/17391793#17391793
