Hi,

I came across this problem in using the threads package.

I used the following files:

boost_thread-vc71-mt-gdp-1_31.lib

boost_thread-vc71-mt-gdp-1_31.dll

boost_thread-vc71-mt-p-1_31.lib

boost_thread-vc71-mt-p-1_31.dll

While trying out a simple example from the test folder:

#include <boost/thread.hpp>

#include <boost/thread/xtime.hpp>

using namespace boost;

…………

…………

…………

void HelloWorld()

{

}

…………

…………

…………

// Test threads

boost::thread thrd(&HelloWorld);

thrd.join();

…………

…………

…………

The application gave the following link error:

Abacus error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall boost::thread::thread(class boost::function0<void,class _STL::allocator<class boost::function_base> > const &)" (__imp_??0thread@boost@@QAE@ABV?$function0@XV?$allocator@Vfunction_base@boost@@@_STL@@@1@@Z) referenced in function "public: unsigned int __thiscall mok3::Abacus::Application::init(void)" (?init@Application@Abacus@mok3@@QAEIXZ)

The program works fine without any parameters to the constructor ( boost::thread thrd; ), but of course that’s not useful. If it were a syntax error it should be at compile-time, but there is no problem during compilation.

Also, if there is a patch for statically linking threads package, it would be appreciated if you could send it.

I am compiling the libraries with the following settings:

Boost_1_31_0> bjam –sTOOLS=vc7.1-stlport –sSTLPORT_PATH=… install

Thanks,

-Vino
