Disable compiler-generated copy-assignment operator [duplicate]

Answer 1

If you inherit from boost::noncopyable you will get a compile time error when the copy constructor is attempted. I have found that using this the error messages (with MSVC) are useless, since they generally don't point to the line that caused the error. The alternative is to declare a copy-constructor private and leave it undefined, or define it with a BOOST_STATIC_ASSERT(false). If you are working with C++11 you can also delete your copy constructor:

class nocopy
{
    nocopy( nocopy const& ) = delete;
};
