Hello Simon,

thanks for the answer and suggestion.

My IDE is CodeBlocks, and I'm running it over Windows Vista 32.

My code is a simple example of the thread lib use:

Code:

#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[])
{
   // inicialize a new thread
   boost::thread my_thread( &hello_world );
   // wait for the thread end
   my_thread.join();

   return 0;
}

It's very simple, and when I try to compile it, I got these errors:

C:\boost_1_45_0\stage\lib\libboost_thread-mgw45-mt-1_45.a(thread.o):thread.cpp:(.text+0x7d)||undefined

CodeBlocks uses MinGW as compiler, and due this is a C++ code, the g++ is
been used (I guess).

note: I've built the boost using MinGW, not msvc.
