I am a n00b. Sad

I am attempting to use the Boost Threads library and I am running into some errors.

Would one of you wizards please assist me with as much detail as you have time for. My project `Includes` folder shows the boost files (/usr/include/boost). In my project properties (paths and symbols), I have included this path in `Library Paths` and `Includes` tabs for both GNU C and CNU C++. Here is my code. It is only a test to see if I can compile. Spawning one thread is my goal.

#include <iostream>
#include <boost/thread.hpp>

using namespace std;

void task1(void)
{
cout << "There" << endl;
}

int main()
{
boost::thread mythread(task1);
cout << "Hi" << endl;
return 0;
}

My Console Ouptut:
**** Build of configuration Debug for project MyThread1 ****

make all
