Hi all,

I am trying to compile some code in Release mode in MSVC 2010, see below error message,

I am looking for a workaround or solution, and so far all I can find is something to do with boost::multi_array https://svn.boost.org/trac/boost/ticket/4874

but the solution and patch seems to be targeted at only multi_array.

Has anyone else tackled this before?

thanks, Paul

I figured it out, utils::output_counter was not assignable, so the compiler could not generate the operator= method for function_output_iterator Making output_counter copyable solved the problem. thanks, I always seem to figure things out about 5 minutes after posting to a list, even after 1 hour of struggling first. cheers Paul
