New MbedTLS issue

[nicksaintjohn]

I have been compiling fine for the past month or two but, having taken a break for a couple of weeks, I have just returned to find that nothing will compile any more. I can only imagine that maybe some update has broken something. I'm unable to even compile the vanilla Lightbulb example.

I receive the following error when attempting to compile: -

[974/1025] Building C object esp-idf/port/CMakeFiles/__idf_port.dir/Users/nicksaintjohn/esp/esp-apple-homekit-adk/homekit_adk/HAP/HAPAccessoryValidation.c.obj

I've tried updating and switching to various versions of esp-idf, sometimes yielding different (now fixed) build errors, but when using the latest build (currently on esp-idf v4.2, esptool.py v3.0) I always get stuck at this same error.

I noticed something similar was reported a few months back (#3), but I'm presumably using a much later build, and therefor this should already be fixed!?

Any help or pointers would be greatly appreciated. I'm on MacOS 11.1 (Big Sur)

@nicksaintjohn , can you double check if you have followed the steps here for setting up mbedTLS?

[nicksaintjohn]

Okay, I switched to that branch (was on HEAD previously), but upon doing a 'git pull' it says I'm already up to date... It does report some issues however, so I suspect that may be the problem.

nicksaintjohn@Nicks-MacBook-Air mbedtls % git branch -l
* (HEAD detached at 90f46c8b1)
  mbedtls-2.16.6-adk
  mbedtls-2.16.7-idf
nicksaintjohn@Nicks-MacBook-Air mbedtls % git switch mbedtls-2.16.6-adk
Previous HEAD position was 90f46c8b1 Fix `maybe-uninitialized` warnings resulting in build failure.
Switched to branch 'mbedtls-2.16.6-adk'
Your branch is up to date with 'origin/mbedtls-2.16.6-adk'.

Could you please suggest how to rectify / diagnose further? Please note, I was able to compile a couple of weeks ago, so I know it was correctly set up in the past. To my knowledge nothing has been changed (aside from a reboot), so I've no idea how anything has broken. Thanks

Ok, seems I've just recompiled, and now it's working again... I'm at a loss as to what happened to screw it up, but you led me to the solution, so many thanks!

Thanks...!!

After switch using this command solved, for me...!

git switch mbedtls-2.16.6-adk
