Hi Guys
I am try to create a thread with boost but eveytime I execute I get some
freaky error messages. See code below followed by error msg:
#include
#include <iostream>
using namespace std;
void hello()
{
cout << "hello" << endl;
}
int main(int argc, char* argv[])
{
boost::thread thrd1(&hello); // ERROR caused by the &hello param
thrd1.join();
}
*Error Message*:
