Help with Heavy Compiler API

I've had luck using this API within JUCE but I'm getting some errors when trying to use it to create new Teensy audio library objects.

In JUCE I'm able to create a new context using

HeavyContextInterface* context = hv_sine440_new(44100);

Then I can use the processinline function. When doing this in Teensy I get undefined reference errors for hv_processInline and hv_sine440_new. I've included the main Heavy_sine440.h file in my .h file for the audio object.

Does anyone have experience with hvcc or know what piece I may be missing in using this API on Teensy?

Could you post the contents of Heavy_sine440.h? Their documentation doesn't have a full example with source (as far as I can see) to tell where stuff is located.

Seems like a cool library though.

Once I put all the files from the API in the sketch folder directly I got it to compile. Not a big deal, I guess compilation works differently for files in subfolders. I'll report back when I've tested some patches on my Teensy.
