Hi All, I started on boost today and wrote my first hello world application.
#include <boost/thread/thread.hpp>
#include <iostream>
using namespace std;
void hello_world()
{
cout << "Hello world, I'm a thread!" << endl;
}
int main(int argc, char* argv[])
{
boost::thread my_thread(&hello_world);
my_thread.join();
return 0;
}
I compiled it using the command. g++ helloworld.cpp -lboost_thread-gcc41-mt-1_34_1
However, when I try to run it, I keep getting a segmentation fault. I tried to debug with gdb and this is what I get.
(gdb) run
Starting program: boost_test/a.out

Please let me know as to what I am doing wrong. Any help is appreciated.
Thanks

First try compiling with -g. This enabled debugging in gcc/g++. I will try to find the error. Kind regards, Hans
