Another problem (I think) is that with BOOST_STATIC_ASSERT you know compilation will stop. However, a BOOST_STATIC_WARNING would keep re-apearing in each translation unit #including your file: // boost_file.hpp BOOST_STATIC_WARNING( "we're in boost_file.hpp") // file1.hpp #include <boost/boost_file.hpp> -- appears here // file2.hpp #include <boost/boost_file.hpp> -- appears here too!
