Re^6: Perl 64-bit versions by BrowserUk (Patriarch) on Mar 13, 2012 at 16:16 UTC
Whilst it is possible to have multiple concurrent versions of Perl installed -- I have 5.8.9 32-bit and 5.10.1 64-bit -- and manage them using the windows alternative to shebang lines -- assoc/ftype/.pl/.pl8 -- I've tried it in the past and just find it a pain to work with. The multiple versions rather the extensions. Whichever version I'm using, it always seems that the module I want to use is already installed everywhere but that version. The biggest pain is needing to work out which modules are pure perl and can just be copied over and which have a binary component that need proper installation. Whilst the split between perl/lib and perl/site/lib has always seemed entirely pointless and arbitrary to me; maintaining a split between pure perl pacjages and those with a binary component seems like it would (have been) far more useful. Way to late now of course. As an aside: do you perchance have a 64-bit 5.15.something installed anywhere? If so, could you try: `perl -wE"$v=''; vec( $v, 2**32, 1 )=1"` [download] And see if the 31-bit limitation on vec has been lifted? With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice. The start of some sanity?	[reply] [d/l]

Those in $arch (e.g. i686-linux-thread-multi) vs those that aren't. Perl can be setup to peek into the libs of previous version, and that's how it determines what's safe and what's not.	[reply]

Whilst the split between perl/lib and perl/site/lib has always seemed entirely pointless and arbitrary to me Well, it does allow you to get to a pristine core installation in seconds. Yeah, it's of limited value. But who cares.	[reply]
