I am trying to build this, I used:

I installed the rust toolchain (following the quick start tutorial) and the esp toolchain. The esp32-hal is building fine.

I'm not sure what the root of this problem is (sorry) but I believe it stems from LLVM. In Matrix some people found that building with --release seems to fix this. This obviously isn't an ideal solution but it may be enough to get you going for now. Are you able to confirm this is the case?

Thank you. Yes, it works with --release.
