Bug 1470542

(In reply to Johan Vromans from comment #0)
> /tmp/parlJ7MK: Perl lib version (5.24.1) doesn't match executable 'perl'
> version (5.24.0) at /usr/lib64/perl5/Config.pm line 62.

This exception comes from /usr/lib64/perl5/Config.pm that on my system comes from Perl 5.24.1:

$ rpm -qf /usr/lib64/perl5/Config.pm 
perl-5.24.1-386.fc25.x86_64

and the code is:

$^V eq 5.24.1
    or die sprintf "%s: Perl lib version (5.24.1) doesn't match executable '$^X' version (%vd)", $0, $^V;

So it looks like the 'perl' command is and outdated perl.

Does PAR::Packer bundle libperl.so.5.24 library?

If this is true I think we will need to add an explicit Requires on Perl interpreter version that was used to build perl-PAR-Package to catch the right after upgrading Perl.

The latest stable perl-PAR-Packer package is 1.035-2.fc25. And that has already been rebuilt against Perl 5.24.1. I recommend you to upgrade.

I will still investigate the cause and try to correct the dependencies.

I think the best answer to this question is "yes".

That would be helpful, indeed.

Now I can see it. When building perl-PAR-Packer, myldr/Makefile.PL links parl from boot.o that is compiled from boot_embedded_files.c that is generated by embed_files.pl tool whose input is "/lib64/libperl.so.5.24.1", the libperl.so shared library. So it effectively bundles libperl.so into /usr/bin/parl.

Then when building a standalone executable with pp tool, /usr/bin/parl is executed and its embedded libperl.so loads various Perl modules from system, including the Config that fails when checking for the version.

However, in the meantime, perl-5.24.2-393.fc26.x86_64 has also been released and now conflicts with this new build of perl-PAR-Packer.

Is there some means in the build system to require that whenever a new perl package is built, that perl-PAR-Packer must be rebuilt at the same time?

I'm in the state when I have these installed:
perl-PAR-Packer-1.036-3.fc26.x86_64
perl-5.24.2-393.fc26.x86_64

This works because the perl-PAR-Packer-1.036-3.fc26.x86_64 requires:
perl(:MODULE_COMPAT_5.24.1)
perl(:VERSION) >= 5.6.0
perl(:VERSION) >= 5.8.1

.. which are all met. But the new perl-PAR-Packer-1.036-4.fc26 now explicitly depends on
perl(:VERSION) = 5.24.1
which isn't met because perl 5.24.2 is already installed.

Please re-build and release perl-PAR-Packer against perl 5.24.2 ASAP, and figure out a way to make sure these packages are always built and released in lock-step.

Perl has been updated to 5.24.2, and history repeats...

rpm --requires -qp ~/tmp/perl-PAR-Packer-1.035-3.fc25.x86_64.rpm
...
perl(:MODULE_COMPAT_5.24.1)
perl(:VERSION) = 5.24.1
...

Fedora build infrastructure does not support automatic rebuilds. We have to rebuild it manually. With the perl(:VERSION) dependency we at least know before installing it.

Same issue just came up again on F29 as a perl update to 5.28.1 is incoming:
 Problem: package perl-PAR-Packer-1.047-1.fc29.x86_64 requires perl(:VERSION) = 5.28.0, but none of the providers can be installed
  - perl-libs-4:5.28.0-423.fc29.i686 has inferior architecture
  - cannot install both perl-libs-4:5.28.1-427.fc29.x86_64 and perl-libs-4:5.28.0-424.fc29.x86_64
  - cannot install both perl-libs-4:5.28.0-423.fc29.x86_64 and perl-libs-4:5.28.1-427.fc29.x86_64
  - cannot install the best update candidate for package perl-libs-4:5.28.0-424.fc29.x86_64
  - cannot install the best update candidate for package perl-PAR-Packer-1.047-1.fc29.x86_64

Please re-build perl-PAR-Packer against this new perl build.

Thank you for the notification. I will rebuild it for Fedora 28 too.

Unfortunately DNF does not support querying exact dependency versions (dnf repoquery --whatrequires 'perl(:VERSION) = 5.26.2') and the notifications from a compose log are broken and disabled for last few months, thus there is no way of automatically discovering there dependency breakages.
