assignment operator could not be generated
When building a project that uses boost on Windows under MSVC 9.0 (VS 2008), I get _tons_ of warnings for "assignment operator could not be generated" all throughout the code. Is this going to cause subtle errors when I run the code, or are the warnings harmless ones that can be disabled with pragmas? One example where I get lots of "assignment operator could not be generated" spam is in boost::detail::addr_impl_ref<T> when I try to use boost::bind. But there are many other places as well. I can produce an explicit sample if requested, but since it happens so frequently and I haven't done anything special AFAIK to make it happen, I suspect someone else will immediately know what I'm talking about.

They can be ignored or disabled with /wd<n> (disable warning n)

That one has already been fixed on main and merged to the release branch.
But there are many other places as well.
Open trac tickets for each one and they'll get fixed. Thanks. -- Eric Niebler BoostPro Computing http://www.boostpro.com
