Hi, I try to build my C++ library with the /clr option to make it visible to managed world. I get a linker error: warning LNK4248: unresolved typeref token (01000027) for 'boost.detail.win32._SECURITY_ATTRIBUTES'; image may not run I found the ticket#2226 (https://svn.boost.org/trac/boost/ticket/2226) which say that 'Boost thread does not work with managed C++ when statically linked.' How can I solve this issue? I need to link it dynamically? Regards, Daniele.
