[Boost-users] Boost::serialization detection of Cxx Standard

Hi, I developed a patch and a test to serialize std::pmr::(w)strings in all 3 archive types. The test I set the requirement to <cxxstd>17. It works so far but when I compile the library for using it in my application the "hidden" functions behind "BOOST_NO_CXX17_MEMORY_RESOURCE" are not found by the linker as the define is set when the library is compiled. How to work around this? Bye Georg
