Yup. Nothing to do with auto-linking either since gcc doesn't support that,
it's purely a symbol visibility issue, and gcc is quite a bit stricter about
what works than msvc.
One thing you could try is building the library and tests on Linux
with -fvisiblity-hidden - you will very likely get lots of unresolved
externals - then it's a case of adding the symbol visibility macros to those
and/or preprocessing the offending source to see why things aren't working
as expected.
HTH, John.
