I have some tests which are throwing up std::auto_ptr as deprecated with C++11. Is there a define that can be tested for in user code so that I can switch to std::unique_ptr when it is available? Something like this: #ifdef BOOST_NO_CXX11_UNIQUEPTR // use auto_ptr #else // use unique_ptr #endif Is there a general flag for C++11 or C++14 or is it all done on particular features? Thanks John

__cplusplus may be helpful. Look at regression tests www.boost.org/development/tests/develop/developer/config.html config_info to see how it is defined for various compilers. HTH --Beman

I have found a test. It is BOOST_NO_CXX11_SMART_PTR and it is set by the standard library in use. On test at the moment. Thanks John

Or you might want to use boost::movelib::unique_ptr for code to be compiled in C++03 and C++11 modes: http://www.boost.org/doc/libs/1_57_0/doc/html/boost/movelib/unique_ptr.html Best, Ion

Ion I have tried your suggestion as an option in my file at boost/libs/phoenix/test/operator/member.cpp on develop branch. I can declare a pointer O.K. but the tests fail to compile with gcc 4.9.0 and C++11, which may be my configuration. Thanks John

Let me know if I can help somehow. Best, Ion
