Ok, you're right, sorry I missed that detail. Though to be clear, I think you mean it is because debian/rules doesn't use LDFLAGS from dpkg-buildflags, it doesn't necessarily have to do with the hardening option. > Note that I plan to introduce soon hardening flags in blas (and possibly > atlas and openblas, though it will be harder).
