HELP!!!!
I'm trying to compile an application which contains boost threads and I can't seem to get it to work. Whenever I try to compile, I get the following two types of messages from the compiler:
warning C4275: non dll-interface class 'std::logic_error' used as base for dll-interface class 'boost::lock_error'
or
warning C4251: 'boost::thread_group::m_threads' : class 'std::list<_Ty>' needs to have dll-interface to be used by clients of class 'boost::thread_group'
Obviously, these have something to do with the mixing of DLL and non-DLL classes, but since Windows is not my preferred OS I have no clue about what to do to get this to compile. I used boost (v 1.28) on a prior project (using VC6) with no problems, but I'm just stumped here....
Can anyone give me a clue?
These are warnings, and these particular warnings are often harmless. What do you mean by "can't seem to get it to work"? Is something else failing?
True, but I *hate* warnings :-)... Seriously, I was under the impression that these would potentially cause problems when trying to instantiate/destroy an instance of one of these classes. I've had a fair amount of bad luck with MS DLL-hell problems, and I'm a bit leery of any type of warnings I get regarding them. I haven't actually tried to run the code, yet so I don't know if it'll fail or not, but if there is some workaround to get rid of the warnings (short of pragma'ing them off), I'd appreciate it... Thanx, Steve
