[serialization] BOOST_CLASS_EXPORT_GUID cant link
Hi, Im trying to use the BOOST_CLASS_EXPORT_GUID, but if i use it, i cant link my project. if got these error messages: /gcc-4.1.2/debug/threading-multi/crabd.o:/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/exception:57: multiple definition of `boost::archive::detail::guid_initializer<water::status>::instance' bin/gcc-4.1.2/debug/threading-multi/seal.o:/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/exception:57: first defined here bin/gcc-4.1.2/debug/threading-multi/water.o:/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/exception:57: multiple definition of `boost::archive::detail::guid_initializer<water::status>::instance' bin/gcc-4.1.2/debug/threading-multi/seal.o:/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/exception:57: first defined here The file with the macros is just one time defined. Is there an other possible reason than multiple definition or a more hidden way to define it more than one time? Kind Regards Manuel Jung
This most likely occurs if you have something like the following in more than one module: #include "water.hpp" // which icludes BOOST...EXPORT #include "../?iarchive.hpp" #include "../?oarchive.hpp" to fix this - make sure you include .../archive.hpp in only one module.

Hi, Yes this did the trick, thanks. The EXPORT Scripts were in a header file and thus included more than one time from different cpp files. Thanks! Greetings Manuel Jung

I've been putting these macros into cpp files where possible, which prevents this sort of thing from happening, but I am doing this stuff in libraries so that's really the only option. James
