error: implicit declaration of function ‘strlcpy’; did you mean ‘strscpy’? (Ubuntu)

[sebastianrueckerai]

Hi!

I am on Ubuntu 22.04.5 LTS with Kernel 6.8.0-45-generic.

I am getting the below error while building. Any help would be greatly appreciated! :)

I was able to fix this by changing:
strlcpy(f->description, pixfmt->name, sizeof(f->description));
to
snprintf(f->description, sizeof(f->description), "%s", pixfmt->name);

Build completes now and install runs without error, but also without any log messages.
After rebooting, the card does not work, the test fails:
