Building O2 fails (Clang) on MacOS Catalina 10.15

Hi all,

Building O2 fails on my system after pulling the latest changes. Rebased alidist and updated command line tools but that didn’t solve it. Here is my log.

Did anyone face this?

Thanks for your help.

Cheers, Audrey

For reference: fixed after upgrading to BigSur and reinstalling o2.
