I am running 

perl -V

and I get 

Can't undef active subroutine at /usr/local/lib64/perl5/Config_heavy.pl line 1418.
Compilation failed in require at /usr/lib64/perl5/Config.pm line 79.

this was after a 

yum reinstall perl

How can I resolve this and get a working perl installation on centos 7

  • There is a drastic solution: removing then installing. yum remove perl yum install perl – David Verdin Jan 06 '17 at 09:53

    The yum reinstall was perfomed a while back. I have tried yum history undo and i get no package matched to remove xxx error. – eastafri Jan 06 '17 at 09:54
  • @DavidVerdin what are the greatest risks for this? I have perl version 5.16 maybe try and install that same version since it is a system perl install. – eastafri Jan 06 '17 at 09:56
  • Well, no greatest risk than not having perl working at all. – David Verdin Jan 06 '17 at 09:57
  • Wait: is it a production server? – David Verdin Jan 06 '17 at 09:58
  • It is on our computing cluster and I can call it the production server. A lot of tools including slurm are dependent on the cluster system perl. – eastafri Jan 06 '17 at 09:59
  • I see that rpm is wirtten in C AND Perl. So if you simply remove Perl, I don't know if RPM will still be working. You might need to try running yum reinstall perl again before trying more drastic solutions. – David Verdin Jan 06 '17 at 10:04
  • There are suggestions about a similar problem in this other question: http://stackoverflow.com/a/25818900/6193608 – David Verdin Jan 06 '17 at 10:14
  • Many thanks @DavidVerdin I ran yum reinstall perl. It does not resolve the problem. – eastafri Jan 06 '17 at 10:56

    Do you have root access? Build from source and install it as system perl (for example, in `/usr/bin/perl`). Try to build the same version as the old system perl. – mob Jan 06 '17 at 15:56
