Normally the linux-compiler-gcc-* packages express the required compiler version for building kernel modules and handle this, but they're only an upgrade ratchet, not a downgrade ratchet. (Plus, that would just create an unsatisfiable dependency since the compiler packages aren't broken apart that way.) > If the minor version really matters, why Debian doesn't ship different > packages, such as gcc-6.3 and gcc-6.4? I suspect that usually only the kernel is affected. -- Russ Allbery (r...@debian.org) <http://www.eyrie.org/~eagle/>
