boost::thread build error (unable to link lib && unresolved external)

Question

Hi all,

I'm trying to follow a simple tutorial of Boost::Thread (ver 1.4-3) in VS 2008:

#include <boost/thread/thread.hpp>

void Func()
{
    // Do something
}

void main()
{
    boost::thread _thrd(&Func);
    _thrd.join();
    ....
}

During compilation it produces this error:

Error 1 fatal error LNK1104: cannot open file 'libboost_thread-vc90-mt-gd-1_43.lib' CConsole

which I have to resolve by adding #define BOOST_ALL_NO_LIB. However, it gives me another error:

Error 3 fatal error LNK1120: 2 unresolved externals 
C:\xx\Documents\Visual Studio 2008\Projects\CConsole\Debug\CConsole.exe


Error 1 error LNK2019: unresolved external symbol "public: __thiscall boost::thread::~thread(void)" (??1thread@boost@@QAE@XZ) referenced in function _wmain CConsole.obj


Error 2 error LNK2019: unresolved external symbol "private: void __thiscall boost::thread::start_thread(void)" (?start_thread@thread@boost@@AAEXXZ) referenced in function "public: __thiscall boost::thread::thread<void (__cdecl*)(void)>(void (__cdecl*)(void),struct boost::thread::dummy *)" (??$?0P6AXXZ@thread@boost@@QAE@P6AXXZPAUdummy@01@@Z) CConsole.obj

Does anyone know how to resolve the issue?

Thanks.

You need to both build the Boost Thread library and tell Visual Studio where the library is. All this is documented in the Getting Started documentation (i.e. Getting Started on Windows). Specifically read section 5 and then section 6.

PS. You need to make sure your build configuration matches what you have VS set to. The Getting Started explains the various build options.
