Perl Snapshot and moving to 64 bit
Posted by simonw on Tue 17 Aug 2010 at 17:10
Trying to migrate from 32 bit to 64 bit web server.
Perl autobundle based approach didn't look like they would ever leave me a working set of local perl modules (and definitely not till several days of installing was past), so I rsync'ed /usr/local/share/perl and /usr/local/lib/perl.
None of the compiled code in /usr/local/lib/perl is usuable as it is 32bit code, but cpan has a "recompile" option for just this sort of situation. A couple of modules failed automatic recompilation, but doing cpan "force install" of two that failed, and two dependencies, and it was left complaining about an in-house Perl module written in C (huh?) - at which point my System Admin hat is removed, and my "can I remember how to write C" hat replaced it.
It took a lot of reading before I noticed the "recompile" command in cpan. If you need to use it you've probably gone wrong, on the other hand ~5500 perl modules installed and working before lunch.
