C++ / mysql Connector - undefined reference to get_driver_instance - already tried the easy stuff

Question

Yes this question has been asked before ... I\'ve tried everything mentioned in the previous answers. My setup is really straightforward so this shouldn\'t be so hard.

Answer 1

So I have now had this problem for a week now and I became very frustrated with it as well. I just now was able to finally build a program that does nothing except login to mysql and I literally squealed with joy. Here is what I have and I hope it helps.

I first compiled the c++ connector library from source but after a while I thought maybe I did something wrong so I then just used apt to get it with:

sudo apt-get install  libmysqlcppconn-dev

And here is my simple tester source file "tester.cpp"

#include 
#include 
#include 
#include 
#include 
#include 
#include 

using namespace sql;
int main(void){
  sql::Driver *driver;
  sql::Connection *con;

  driver = get_driver_instance();
  con = driver->connect("tcp://127.0.0.1:3306","root","YOURPASSWORD");

  return 0;
}

And finally g++ compile command:

sudo g++ -Wall -I/usr/include/cppconn -o testapp tester.cpp -L/usr/lib -lmysqlcppconn

This worked for me and I hope it helps you solve your problem!
