I'm getting warnings about integer overflow. The problem is at Line 59 of boost/test/tools/detail/print_helper.hpp. It sets an output stream's precision based on the digits given by std::numeric_limits.

That's harmless but annoying: it's because std::numeric_limits::digits is INT_MAX. The stream precision isn't ever used by integer types anyway...

I switched to one of the fixed-sized types (512 bits).

This time it's an error, at Line 59 of boost/test/tools/floating_point_comparison.hpp. There no (close enough) matching function for "fpt_abs" from some "boost::multiprecision::detail::expression<..." type. (It was truncated by the display. I don't know how to get a clean print-out of errors from Code::Blocks.) I'm guessing the expression template setup is screwing things up.

Yes, it's because Boost.Test can't be used with expression template enabled types. It's a known issue, and I've added a patch for this: https://svn.boost.org/trac/boost/ticket/8272, but Genediiy seems to be MIA at present :-(

Do you particularly want to test with expression-template enabled types (I reaslise there are cases when you do)? If not then you could use multiprecision types that have expression templates turned off and that should fix things.

I switched to the same type with expression-templates turned off. Daryle W.
