I need to use kicksecure’s hardened-kernel project, but when I compile /usr/share/hardened-kernel/build I get a compile error with no indication of missing dependencies, before that I installed the hardened-kernel package.
Since it’s related to the Kicksecure project, you should post your issue in their forum.
Indeed this question is not about Qubes OS, so this isn’t the right place for it.
The OP is not a member and doesn’t have access to the All Around Qubes category, so moving the topic is not an option. I’ll close it now.
