Who can give me a sample for how to using boost::thread in a MFC regular dll?
Hello everyone! I have a MFC application that using boost::thread, it runs well. Now I wrapped it to a MFC regular dll, but I get a assertion error when I using this dll. // (In my another MFC dialog application) void AFXAPI AfxCoreInitModule() { ASSERT(AfxGetModuleState() != AfxGetAppModuleState()); // assertion error // the return value of AfxGetModuleState() and AfxGetAppModuleState() are both not-empty, // but they are different. ... } Any advice? thanks!

Try adding at the begining of each exported function this line AFX_MANAGE_STATE(AfxGetStaticModuleState()); Cheers,
Thanks for your help, but it is no way... I have placed my sample project to: http://ddgg.50webs.com/TestBoostThreadDll.rar World you like to help me? Thanks a lot! 2010/4/19 Ismael Bejarano <ismaelbej@gmail.com>:

I've tried with VS 2005 with boost-1.42 and it work as expected (I've to replace CWinAppEx with CWinApp because they don't exists in VS2005). Sorry, but I don't have VS 2008. Cheers,
You are very kind, thank you for your help! I have found the solution, at the last reply of this: http://social.msdn.microsoft.com/Forums/en-US/vcgeneral/thread/ec0ce12e-d54d... // extern BOOL (WINAPI * const _pRawDllMain)(HANDLE, DWORD, LPVOID)=&dll_callback; I commented it and recompiled the boost library, and then the problem disappeared. 2010/4/20 Ismael Bejarano <ismaelbej@gmail.com>:

If you do that then you are liable to leak memory and potentially resources if you use any boost.thread facilities from any thread not started with boost::thread. In particular, boost::thread_specific_ptr variables will not be destroyed when a non-boost::thread thread exits, but other uses of the boost thread library may also leak memory. The best option in this case is to use the DLL build of boost.thread.
