Ask for help. Boost Thread Problem with VS 2005

[Lighter]

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

using namespace std;
using namespace boost;

void hello()
{
cout << "Hello world, I'm a thread!" << endl;
}

int main(int argc, char* argv[])
{
thread thrd(&hello);
thrd.join();

return 0;
}

===================

The above code cannot be compiled in VS 2005. The compiler reports an
error message "Threading support unavaliable: it has been explicitly
disabled with BOOST_DISABLE_THREADS", What's the cause?

Who know the solution to it? Thanks in advance. Any help is appreciated.

I don't have an answer to your question, I'm sorry. I'm a UNIX geek,
so VS 2005 is something I don't pay any attention to.

However, you'll probably have better luck if you ask on a Microsoft or
Visual Studio-specific newsgroup. comp.lang.c++ is meant for questions
about the C++ ISO standard, not questions about specific compilers.

Good luck getting things fixed!

Have you defined BOOST_DISABLE_THREADS in boost\config\user.hpp ?

Just read the boost thread documentation, particularly on
configuration:

http://boost.org/doc/html/thread/configuration.html#thread.configuration.implementation

According to the documentation, a VS project must include the
multithreaded version of the runtime in order to use boost threads.
Furthermore, the #include directives should be:

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

Right. That's the OP's problem.

Furthermore, the #include directives should be:

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

You don't need to manually include <boost/config.hpp>, and the
top-level <boost/thread.hpp> pulls in all the parts of the thread
library, which the OP may not want or need. There's no problem
including just <boost/thread/thread.hpp>, as the author of the library
does in his examples, found here:
