issue about include boost thread header in MFC dll
I have a MFC dll application. I try to use Boost thread in the dll. #include "stdafx.h" #include "interface.h" #include "MFCDLL.h" #include <boost/thread.hpp> // The one and only CMFCDLLApp object CMFCDLLApp theApp; EXPORT32 int __stdcall func() { AFX_MANAGE_STATE(AfxGetStaticModuleState()); ... return DLL_OK; } The build is OK. But when I call the func, it crashes. If I comment the line: //#include <boost/thread.hpp> Then it works well. So how to use thread in MFC dll? -- View this message in context: http://boost.2283326.n4.nabble.com/issue-about-include-boost-thread-header-i...

It could result in errors saying "Undefined Symbols". If you have indeed linked boost thread library with your program then another reason for errors could be that you have used different link flags. I mean that you may have missed "/MT" flag while compiling your program.

Hi, which version of Boost are you using? How it crashes? Have you access to a readable stack? Could you add the compiler command lines? Could you provide a complete example? And last, could you create a track ticket with all these informations? Best, Vicente

I forgot to mention that I am using Visual Studio 2010 and Boost library 1.49. -- View this message in context: http://boost.2283326.n4.nabble.com/issue-about-include-boost-thread-header-i... Sent from the Boost - Users mailing list archive at Nabble.com.
It looks like I can not link to the static thread library. If I changed to dynamic thread library, it seems works. Can anyone confirm that? -- View this message in context: http://boost.2283326.n4.nabble.com/issue-about-include-boost-thread-header-i...
