This actually goes further than that as different version of glibc aren't ABI compatible with one another.

  They are backwards-compatible (which is all you can do of course).

    Are they ? If seen my share of old x64 binaries refusing to run on modern linux distro, spouting some sort of undecipherable glibc error message on startup (something along the lines of "version `GLIBC blah' not found)
    • floatboth 7y ago
      That message happens when a new binary is run on an old glibc, not the other way around.
      • ur-whale 7y ago
        Yes, you'd think so indeed. Unfortunately, I've seen the exact opposite in production: older binary running atop newer glibc and crashing with that kind of message. glibc abi compatibility is and has been a joke.
