Compilation failure using BME680 with bsec on 2026.2.1

ESPHome
1

I have several projects that use the BME 680 with BSEC2, which have worked fine for over a year.
Having recently updated my ESPHome to 2026.2.1, I find these projects no longer compile, (they were fine with 2026.1.5).
I won’t spam you with the whole configuration because until this update they had no issues.
Has anyone else faced a similar problem?

I just performed a Clean All Files then an Install - Wirelessly

This error occurs:

Does this help?

Thanks, this seems to solve the problem.

The best fix seems to be switching to the esp-idf platform, I was still on arduino
