Re: [Boost-users] Weird problem with boost::noncopyable and boost::mutex

The thing is that I instanciated an ArrayList object and called the "insert" method and I received an error from boost::mutex AND boost::noncopyable!! and I am not using them at all!! This is the code that generates the error:         ArrayList<ObjectA> myArrayListA;         ObjectA myObjectA;         myArrayListA.insert(myObjectA);

Maybe ObjectA has a member of type boost::mutex? insert() invokes compiler-generated copy-constructor of ObjectA, which in turn tries to copy the mutex. In short, you ObjectA is non-copyable.
