I'm working on a problem where I have a code sample from biogears https://github.com/BioGearsEngine/core Where my XSD CodeSynthesis generated code fails the one definition rule when compiled against an gcc5.4 armhf compiler. I regularly build the same files against gcc5.4 arm64 MacOS & Linux and Visual Studio 2017 Win64. I can also build against gcc5.4 aarch64. I'm including an example from my drive account that reduces this to two compilation units. Saddly, this requires a number of headers from XSD and Xerces-C to compile so they are included as well. https://drive.google.com/open?id=1xfzEyugXOGKYuj69JKD2RXqbMBQ4ro4r I'm hopping the mailing list can point me in to some build chain or output format difference between arm7 and arm8 that might be the cause. Or a difference in the ubuntu 16.04 cross-compiler default flags. I'm going to admit. I can't really decide where to start on this so any help is appreciated.
