Recently I had some trouble to linking boost statically into a DLL. After searching around I found that there has been a discussion on http://boost.2283326.n4.nabble.com/Fwd-Thread-Solution-to-conflict-with-MFC-... However it seems that the patch proposed there (see below) did not make it into the trunk. Has there been a special reason why this has not been included into the normal distribution? Cheers, Carlos /**  *  tss.cpp  *  *  This file is intended to correctly build a dll using boost::thread  *  It is taken from  *  * http://boost.2283326.n4.nabble.com/Fwd-Thread-Solution-to-conflict-with-MFC-...  *  *  $Id$  */ #include <windows.h> #include <boost/thread/detail/tss_hooks.hpp> extern "C" BOOL WINAPI RawDllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID); namespace {     BOOL WINAPI dll_callback(HANDLE h, DWORD dwReason, LPVOID p)     { #ifdef _DLL         if(!RawDllMain(static_cast<HINSTANCE>(h),dwReason,p))             return false; #endif // _DLL         switch (dwReason)         {         case DLL_THREAD_DETACH:             boost::on_thread_exit();             break;         case DLL_PROCESS_DETACH:             boost::on_process_exit();             break;         }         return true;     } } extern "C" {     extern BOOL (WINAPI * const _pRawDllMain)(HANDLE, DWORD, LPVOID)=&dll_callback; } namespace boost {     void tss_cleanup_implemented()     {} }
