[odb-users] Linking problem at Ubuntu 16.04

[Sean Clarke]

I have never been able to use the supplied binaries on Ubuntu (15.1 and
16.04), I "believed" this was down to the ABI change and "assumed" it was
because the old binaries had been compiled with the old ABI and all my code
used the new ABI, however looking at you errors that is not the case as and
ABI incompatibility with gcc gives errors something similar to:

src/system/some_system.so: undefined reference to `some_namespace::some
_class::some_method[abi:cxx11]()'
