I'm curious if boost currently ( or plans to ) support C++/CLI. For the past couple of months I've been using boost in a managed C++ application without any issues ( but with quite a few scary warnings ). I've recently installed the beta VS2005 SP and now my applicaiton crashes with the following error if I link with the boost::thread library. The application failed to initialize properly (0xc000007b). Click on OK to terminate the application. Is this something that should work? I seem to remeber when I initially downloaded boost some mention of it not supporting C++/CLI but I couldn't find that reference again. Since it worked pre service pack should I complain to MS? Is my best bet putting all my boost code inside of a DLL? Here's a simple program which will crash if compiled with /clr. Note that no managed C++ objects are used/created and I haven't instantiated a thread object either. #include <iostream> #include <boost/thread/thread.hpp> #include <boost/thread/xtime.hpp> static void thread_func() { int count = 5; while( count ) { std::cout << "thread func..." << std::endl; boost::xtime xt; boost::xtime_get( &xt, boost::TIME_UTC ); xt.sec += 1; boost::thread::sleep( xt ); count--; } } int main( int argc, const char* * argv ) { std::cout << "running" << std::endl; return 1; } Any pointers would be appreciated.
