Hi all.

I think it's frequently asked question. If so, I'm sorry.

Is there anything feature in Boost that allows to compare strings at compile-time?

You can try to use MPL's string: http://www.boost.org/doc/libs/1_55_0/libs/mpl/doc/refmanual/string.html

typedef mpl::string<'hell','o wo','rld'> hello; typedef mpl::string<'hi t','here'> hi; BOOST_STATIC_ASSERT(!boost::is_same::value);

You don't want to use boost::is_same for this. It only compares the type of the container, not the elements of the sequence. (Consider that mpl::vector and mpl::vector2 are different types but have the same elements.) Use boost::mpl::equal. http://www.boost.org/doc/libs/1_55_0/libs/mpl/doc/refmanual/equal.html Eric
