Bosch BME680 BSEC Arduino library for MPY?

[divergentti]

--- edit ---
This seems to be not possible.

Bosch is publishing only .a drivers, not actual source codes. Skipping this idea.

It seems that Bosch has an IAQ (Airquality) etc. calculations in Adafruit library, written in C. [Available from Github] -> (url)

I have build environment ready, but I do not know where to I shall add the BSEC-Arduino driver? Should it be done with make -C mpy-cross from ../py path?

... compiler seems to work ...
