I am working on bugs in boost phoenix. I have found some problems eg. #7624 which run fine with C++11 with either Clang 3.4 or gcc 4.8.2. I also have a patch which has been suggested for bug #8704 which uses C++11. Is there a way to incorporate C++11 only code into tests or the actual headers. If so, is there an example of how to do it in Boost? Thank you John Fletcher

This is what I do it in Boost.Smart_Ptr tests around C++11 only features: https://github.com/boostorg/smart_ptr/blob/develop/test/make_unique_args_tes... e.g. Any tests relating to std::unique_ptr features are entirely enabled only when BOOST_NO_CXX11_SMART_PTR is not defined. Any specific test cases within that code are enabled only when certain C++11 features are present; e.g. if BOOST_NO_CXX11_VARIADIC_TEMPLATES is not defined. Glen

Boost.Config defines many macros to test whether some C++03 or C++11 features are available. Try to use those as much as possible instead of doing your own compiler detection logic. <http://www.boost.org/doc/libs/release/libs/config/doc/html/index.html>

Mathias Thank you, I have selected the following which seems appropriate for my cases. #ifndef BOOST_NO_CXX11_DECLTYPE // C++11 version #else // C++03 workaround if available. #endif I am going to post a test using this to develop. John
