Hello, I’m using boost ::threads and boost ::signals with Visual C++ 7.0 and I have these damn link errors that I can’t remove:

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)

I’ve compiled the boost libs with bjam and the vc7 toolset (I’ve tried with msvc and msvc-stlport, since I use STLport and the result is the same). The weird thing is that I call other methods on thread (join() for example) that are properly linked. My project uses the multithreaded DLL runtime librairies. Any idea of what might be happening? When I look into the built DLLs and LIBs with dumpbin, the symbols all seem to be there except that their decorated names don’t start with “__imp_?”. I’m not sure if this is important or not…

Any help would be really appreciated!!!!
