That looks like the machine doesn't support atomic 64-bit compare-and-swap, or at least the compiler thinks it doesn't. The module is fundamentally reliant on having access to such a CPU instruction, and won't be portable to pure 32-bit architectures. This is actually the first such failure I've seen, though. Note that the nominally 32-bit x86 acquired the requisite 64-bit instruction (cmpxchg8b) many years ago, and so there are plenty of machines that support that without being fully 64-bit. I've also seen a successful test on 32-bit ARM (little-endian). For a big-endian test, the first platform I'd look for is SPARC 64-bit. I don't have ready access to one myself. Regrettably, the CPAN Testers results are almost all for amd64, with a smattering of x86 and the aforementioned ARM. I'm not aware of anyone having actually run it on a big-endian machine so far. The big-endian magic is thus theoretical and untested, but I have considerable confidence in it. -zefram -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
