C++ Compile Error, Help Needed - ld: symbol(s) not found for architecture x86_64

I am trying to get this to compile, but every time I go to compile main.cpp I get the same error: 

Undefined symbols for architecture x86_64:
  "tlogic::tlogic()", referenced from:
      _main in ccAcayG4.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status

I tried debugging it for a while, but the error seems to persist. Any help would be appreciated.

Here is main.cpp:

#include <iostream>
using namespace std;

#include "tlogic.h"

int main()
{
        tlogic test;

        exit(EXIT_SUCCESS);
}

tlogic.h:

#ifndef TLOGIC_H
#define TLOGIC_H

class tlogic {
public:
        tlogic();
        tlogic(bool);
        ~tlogic();
        void init();
        void get_command();

private:
        bool debug;
};

#endif

And finally, tlogic.cpp:

#include <iostream>
using namespace std;

#include "tlogic.h"

tlogic::tlogic()
{
        cout << "Testing" << endl;
        debug = false;
}

tlogic::tlogic(bool debug_)
{
        cout << "Testing 2" << endl;
        debug = debug_;
}

tlogic::~tlogic()
{
}

void tlogic::game_init()
{
}

void tlogic::get_command()
{
}

Thank you for the help.

EDIT: Fixed tlogic::glogic, etc.

You need:

g++ -o prog main.cpp tlogic.cpp

When you are compiling and linking in a single step you need to make sure that you pass all of the source files required to make your complete program to the compiler.
