Subject: 64 bit detection does not work with perl 5.8.x
See http://www.cpantesters.org/cpan/report/a947dd60-8f84-11e3-8d37-07dae0bfc7aa for a sample report. The error message "OS unsupported - no 64bit integers", but the build was run on a amd64 machine, so this is not true. I assume the problem exists because perl 5.8.x has no support for pack('q',...) Regards, Slaven

Not entirely. The messge should probably more accurately read "no support for packing 64bit big-endian integers". The problem for 5.8 is that pack doesn't understand the '>' big-endian specifier. This will mean that Protocol::CassandraCQL::Type::BIGINT and the various other related types (COUNTER and TIMESTAMP), will have problems. Additionally, without endian support for d> and f>, we can't pack FLOAT and DOUBLE types. If you particularly needed this on perl 5.8, it could be done by providing some kind of workaround versions of the following pack formats in a perl 5.8-compatible way: Show quoted text
q> Q> d> f>
However, it's some effort to go to to support a triple (and soon-to-be quadruple) EOL'ed perl version, so I wasn't going to bother up-front. -- Paul Evans

I am perfectly fine with a "use 5.008; # extended pack support" on top of the Makefile.PL. I just wondered because the diagnostic message was not correct in this case. Regards, Slaven
