undefined references building plugin (fresh clone, Windows, updated MINGW64)

[Paul-Dempsey]

Just cloned this repo, building in full Rack environment (not SDK) on Windows with a freshly updated MINGW64, and I'm getting these two unresolved externals when building this plugin for bogaudio::VCF::minFrequency and bogaudio::FollowerBase::efGainMaxDecibels.

I do see both definitions of them. Is this related to them being static constexpr? This is new to me, since I'm just getting back to C++ for the first time since ~2006, and not used gcc before. I didn't see any special instructions in the README for building.

Any idea what's wrong, or clues to where to look?

What's the compiler version? 'gcc --version'?
