error: undefined reference to typeinfo about arduino-trimwright HOT 6 OPEN

Thanks for the report. I'm not super-strong on C++ so this is curious to me too. What compiler (and version) are you using?

Since inheritance is used so lightly, if no other solution turns up I can always add a #define to conditionally adjust things.

Oh hmm... this gives a clue:

This seems to suggest that whatever build environment you have is not also compiling and linking TrimWright.cpp.

I am building the Android Tree
I had looked at the link you mentioned and that gave a clue what it was due to a virtual function. By piecemeal adding the SM parts to my code, I figured out that it was the virtual declaration of the dispatch function.

Hmm... the fact that you fixed it by commenting out the virtual suggests that your environment is probably compling and linking TrimWright.cpp. That same stackoverflow page mentions a few other causes (I should have kept reading). This makes me think that there might be value in dropping the inheritance (HSM no longer inherting from FSM), at least as a #define guarded option.

I've created PR #6 which makes it so that HSM no longer inherits from FSM. Without that, lack of RTTI should hopefully not be an issue. Could you try it out?

from arduino-trimwright.

Sure. Hopefully have it checked by Wednesday.
