Subject:

Shared perlbrew doesn't work as expected

I tried to install perlbrew for multiple users (Debian), as described in : http://gugod.org/2010/12/a-shared-perlbrew-root-for-multiple-users.html I believe that I followed the different steps correcly (although I may have misendurstood something). However, I am trapped between two things : 1. Either I give write permission to all all users on /opt/perlbrew, and it works, but the switch command issued by any user affects all others ; 2. Or I do not give such permission, and then nothing happens. More exacly perlbrew says "Switched to whatever" but simply doesn't do it. Example: $ perlbrew switch perl-5.12.3 Switched to perl-5.12.3 $ perl -v This is perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi ... cat .perlbrew/init # DO NOT EDIT THIS FILE export PERLBREW_PERL=custom ...

I played around a little more. This seems to be connected to the fact that perlbrew sets system-wide symlinks: $ perlbrew switch /usr/bin/perl Switched to /usr/bin/perl as custom $ ls -l /opt/perlbrew/perls/ total 8 lrwxrwxrwx 1 jean perlbrew 6 6 mai 17:07 current -> custom ... $ perlbrew switch perl-5.12.3 Switched to perl-5.12.3 $ ls -l /opt/perlbrew/perls/ total 8 lrwxrwxrwx 1 jean perlbrew 11 6 mai 17:07 current -> perl-5.12.3 ... I am confused, since Gugod's post said "Each user now has a personal init file at ~/.perlbrew/init, which is auto-generated to store the result of perlbrew switch. Not using symlink anymore so there is no permission problem in the way."

The `current` symlink was removed since, iirc, 0.13 release, and then reverted recently in 0.16 due to a some weird behavior. Eventually it should be removed again.

Thanks for the explanation ! It is probably worth an edit on the original blog post (I was unable to comment there, since a login seems to be needed).

Sorry if that bugs you. I've been working on the implementation to remove the need of 'current' symlink. It should be release in about a week (unless my $client bugs me too much :) I will then make an announcement that describe this major change.

The recently released 0.21 should be stable enough resole this issue. I shall start to aggregate relevant documents to the web site.
