boost::serialization - duplicate symbol from portable_binary_*archive
::find(boost::serialization::extended_type_info const&)in /Users/jo/ Documents/packet_serialization_test/build/ orchid_packet_serialization.build/Debug/
If you include the file "portable_binary_iarchive.hpp" or "portable_binary_oarchive.hpp" in a common header the result is: ld: duplicate symbol boost ::archive ::detail ::archive_pointer_iserializer < portable_binary_iarchive packet_serialization_test.build/Objects-normal/i386/packet_base.o and / Users/jo/Documents/packet_serialization_test/build/ orchid_packet_serialization.build/Debug/ packet_serialization_test.build/Objects-normal/i386/main.o
Never-mind, it wasn't intended to be used as a header lib. :-) On Apr 18, 2008, at 9:03 AM, j.c. wrote:

Good morning, I suspect it to be the serialization library version. It's the same information the native binary_oarchive generates when called with the no_header flag. Christian

Hello JC, does this also occur if you replace the archives with binary_[io]archive? Please keep in mind that portable binary archive really is a thin layer on top of the native binary archive, so naturally they mimik their behaviour. I suspect this to be a boost::serialization issue; I never ran into the linker problem you describe. Regards, Christian
