non dll-interface class 'boost::noncopyable_::noncopyable' used as base for dll-interface class 'boost::contract::detail::checking' #23

Closed jeking3 closed 5 years ago

This is from a teeks msvc 14.2 build that boost-ci doesn't have in it yet. Likely all other windows builds are issuing the same warning however.

I fixed quite a few warnings in develop (but I haven't merged into master yet). Looking at the test matrix for develop I don't see warning for msvc-14.2: https://www.boost.org/development/tests/develop/developer/contract.html The link above is from master. Is the warning C4275 above from develop or master?

Looks like it was from master.

This should be fixed in develop.
