Hey, which version of macos are you using?

I see that getentropy might be missing on some older version of macos

darvik80 commented 2 months ago

Lastest version: 14.6.1 (23G93). I updated all that I can :) In fact fix quite simple: components/esp_hw_support/port/linux/esp_random.c ...

include <sys/random.h>

...

ESP-Marius commented 2 months ago

Ah, we have actually already fixed this on master, but I missed the fact that you are on 5.3 and the fix hasnt been backported.

I'll make sure we do that.

ESP-Marius commented 1 month ago

Should be OK now. Closing this issue.
