[Boost-users] [serialization] unable to link on OS X when MACOSX_DEPLOYMENT_TARGET=10.7

Hello, I'd like to build the boost_serialization library with a compatibility setup for Mac OS X version 10.7, because I need to use it with Anaconda Python binaries, which are built for OS X 10.7. The OS X compatibility version can be set either by passing `-mmacosx-version-min=10.7` as a compile and link option or by setting environment variable MACOSX_DEPLOYMENT_TARGET=10.7. If I do so, the boost_serialization library builds without complaints, however I am not able to link it with my test program. Here are the steps I take to compile boost_serialization and the test program starting from a fresh boost 1.64.0 tree: # -------------------------------------------------------------- $ export MACOSX_DEPLOYMENT_TARGET=10.7 $ ./bootstrap.sh $ ./b2 -j4 variant=release link=shared --with-serialization stage # The stage/lib directory now contains libboost_serialization.dylib. # Use it to build a test program from tarchive.cpp: $ c++ tarchive.cpp -I. -Lstage/lib -lboost_serialization Undefined symbols for architecture x86_64: "boost::archive::basic_binary_oprimitive::init()", referenced from: boost::archive::binary_oarchive_impl::init(unsigned int) in tarchive-5e24a9.o "boost::archive::basic_binary_oprimitive::save(std::string const&)", referenced from: void boost::archive::save_access::save_primitive(boost::archive::binary_oarchive&, std::string const&) in tarchive-5e24a9.o ... # -------------------------------------------------------------- The only thing the test program (attached) does is to instantiate the boost::archive::binary_oarchive class. The procedure above works fine when MACOSX_DEPLOYMENT_TARGET is set to 10.9 or higher. Am I missing some option that would fix the failed linking when building for OS X 10.7? I suppose this could be related to object visibility options as the serialization library is compiled with "-fvisibility=hidden" and "-fvisibility-inlines-hidden" options. Thank you, Pavol
