Android Ndk + Two Shared Libraries + Rtti + Dynamic Cast = Impossible

I've been at this for 4 hours so far on a Sunday. I'm about to give up. I've tried literally every post I've found on the internet and this simply will..not..work! Any instance of

Solution 1:

The C++ ABI makes it tricky to get RTTI right when dynamically loading libraries. Each of your types must have a key function (a virtual, non-inline, non-destructor method) for RTTI to work across shared library boundaries.
