in thread "Installed" Perl 5.34 , sort of

I don't have // in any of my @INC paths:

$ perl -E 'say for @INC' /home/ken/perl5/perlbrew/perls/perl-5.34.0/lib/site_perl/5.34.0/cygwin +-thread-multi /home/ken/perl5/perlbrew/perls/perl-5.34.0/lib/site_perl/5.34.0 /home/ken/perl5/perlbrew/perls/perl-5.34.0/lib/5.34.0/cygwin-thread-mu +lti /home/ken/perl5/perlbrew/perls/perl-5.34.0/lib/5.34.0

I suspect you may have done something in your installation which caused this; however, without knowing the steps you took, I don't know what that might have been. Do note the differences between your /opt/local/perl5//lib/site_perl/5/34/1 and my /home/ken/perl5/perlbrew/perls/perl-5.34.0/lib/site_perl/5.34.0:

  • At the start: you have /opt/local; I have /home/ken.
  • In the middle: you have //; I have /perlbrew/perls/perl-5.34.0/.
  • At the end: you have /5/34/1; I have /5.34.0.

There are potentially a number of things you may need to change.

Having // in a path is not a problem in itself: x/y and x//y are effectively the same.

$ ls -al x/y ls: cannot access 'x/y': No such file or directory $ mkdir -p x/y $ cd x//y $ pwd /home/ken/tmp/x/y $ cd ../.. $ pwd /home/ken/tmp $ cd x/y $ pwd /home/ken/tmp/x/y $ cd ../.. $ pwd /home/ken/tmp

    Let me ask another way... My @INC seems screwy. I do configure and make and make test and make install- how early in that process can I see @INC, and how can I view it?

    TYVM and happy Friday to all Monks!

      I suggested Perlbrew which I had assumed you used because you wrote:

      "I looked at this also. [... various steps you performed ...] My @INC looks a lot better ..."

      You don't need "configure and make and make test and make install". Review the link I provided; you'll see you just need

      perlbrew install perl-5.34.0

      You can use other versions. At the time of writing, that webpage has "© 2021": 5.34.0 was released on 2021-May-20; 5.34.1 was released on 2022-Mar-13; 5.36.0 is probably just around the corner (see perlhist for other release dates if you're interested).

    TYVM sir your comparison is helpful. I'm investigating whats in /etc/profile.d I suspect there are some paths in there messing things up.

    As far as the //, likely there is an ENV path somewhere ending in /, and the make somewhere , blindly added /more_dirs, I suspect.

    I rebuilt everything today as root (for make install) with no errors, I got the OK at each step. Then I use CPAN to add some modules, but oddly, now I'm having to go in and chmod a bunch of the pm's because the privs are wrong- like dozens, maybe hundreds:
    [root@newnode Socket]# ls -l total 20 -r--r--r-- 1 root root 12778 Nov 2 2021 -r--r--r-- 1 root root 3971 Nov 2 2021 [root@newnode Socket]# chmod 755 *pm
    I've been building perl since like 1995 and NEVER had these issues. I just performed the cpan instructions of configure, make, make test and make install, nothing special, on a Rocky Linux box. I guess maybe the Rocky part is somehow messing things up?

      Why do you think 0444 are wrong permissions for installed modules? It seems fine to me.


      Those are the correct permissions. Here's some random modules' permissions from my installation (strict [core]; Benchmark [core]; DBI [CPAN]):

      $ ls -l /home/ken/perl5/perlbrew/perls/perl-5.34.0/lib/5.34.0/strict.p +m /home/ken/perl5/perlbrew/perls/perl-5.34.0/lib/5.34.0/ +/home/ken/perl5/perlbrew/perls/perl-5.34.0/lib/site_perl/5.34.0/cygwi +n-thread-multi/ -r--r--r-- 1 ken None 31026 May 22 2021 /home/ken/perl5/perlbrew/per +ls/perl-5.34.0/lib/5.34.0/ -r--r--r-- 1 ken None 4783 May 22 2021 /home/ken/perl5/perlbrew/per +ls/perl-5.34.0/lib/5.34.0/ -r--r--r-- 1 ken None 318199 Feb 1 2020 /home/ken/perl5/perlbrew/per +ls/perl-5.34.0/lib/site_perl/5.34.0/cygwin-thread-multi/

      I've never used Rocky Linux. I'm unable to comment on that.
