Here's the first problem that pops up for me... QNXNTO gcc 4.7.1

Are you linking with a c++11 standard library? Could you do it? Please could you create a ticket? Hi, I have created https://svn.boost.org/trac/boost/ticket/7479 and https://svn.boost.org/trac/boost/ticket/7478 for a similar issue with Boost.ratio. I would try to take care of this tomorrow. BTW, Is there a macro to know if the standard library supports constexpr? Which macro can be used to get rid of this issue?

I have committed fixes for this issue https://svn.boost.org/trac/boost/changeset/80897 and a partial solution for 7478 with https://svn.boost.org/trac/boost/changeset/80896 ( Currently there are no macros BOOST_NO_CXX11_U16STRING and BOOST_NO_CXX11_U32STRING signaling that the standard library doesn't provides std::u16string or std::u32string. The committed change avoids the compile error when Boost.Config will provide these macros. In the mean time the user needs to define them explicitly while using Boost.Ratio in these conditions. ) Please could you check either the trunk or apply the patches associated to the tickets? Best, Vicente
