Hi there,

I'm running into an issue. I'm trying to run stunnel on my new Ubuntu 22.04 system whereas before I was running it on Windows. Thing is, on the Windows system I had to compile stunnel manually as I need to read an encrypted file on the filesystem that contains the user-pin for my HSM. On Windows, that worked. On Ubuntu I'm having issues with the C11 _s functions (like sscanf_s and the likes).

ChatGTP suggested using clang compiler, but I have not clue on how to do that. Of enabling C11 Annex K support in Ubuntu (no such thing, apparently)....

Is there anybody here that makes use of these _s functions in their code on Ubuntu 22.04? Or explain how to use these functions in gcc? Or compile stunnel (+ additional code) using Clang.

Thanks!!

Andreas
