Hi, I used export DEB_BUILD_MAINT_OPTIONS = hardening=+all to fix the hardening issue, but it yields the following error from blhc: CPPFLAGS missing (-D_FORTIFY_SOURCE=2) See https://salsa.debian.org/debian/shc/-/jobs/1126952 I've tried some "solutions" that I found from the internet but nothing worked. Anyone know how to fix this please?
