Vim dependency issues when running dnf upgrade

Am also experiencing dependency issues when trying to upgrade vim even though I don't have vim-X11 installed.

Problem will be solved with perl-libs-5.26.2-410 available in updates-testing.

Should vim really have a hard dependency on a specific version of perl?

Besides:  vim is looking for "libperl.so" using dlopen, and that file is only provided by perl-devel.

E370: Could not load library libperl.so
Sorry, this command is disabled: the Perl library could not be loaded.

Encountered the same issue as the original poster...and I have the same question about the Perl dependency.

Enabling the testing repository allowed me to get to the latest versions of vim and gvim in a consistent fashion:

Anyone know why vim even wants to use libperl.so?

Same here:

It doesn't; not really.  Not until you try to run perl from within vim (or gvim).

In vim you can run the command: ":perl print 'Hello';".

If you don't do that, vim will run perfectly fine even without perl available on your system.  vim has similar feature for pyrhon, ruby, and lua.  And yet vim does not declar a hard dependency on those.

I suggest to just drop the hard dependency on perl, and leave it as a Suggestion.  vim.spec already have this line

    Suggests: python2-libs python3-libs perl-libs lua-libs ruby-libs

and that should be enough.

If you talk about perl(:MODULE_COMPAT_5.26.2) dependency, it is correct by FPG (https://fedoraproject.org/wiki/Packaging:Perl?rd=Packaging/Perl#Versioned_MODULE_COMPAT_Requires - Packages that links to libperl.so).

Perl upstream uses unversioned libperl.so as shared library, but several major OSs (like e.g. Fedora, Gentoo, Debian...) have unversioned libperl.so as symlink to libperl.so.5.26.2, which upstream doesn't use (versioned shared object is created by downstream patch). Vim wants to use the upstream way.

Other interesting thing is that Vim got built with the newest perl, which isn't even in stable repos... maybe buildroot override for perl was active.

Hmm... but FPG doesn't say anything about which dependency should be used... so probably 'Suggests: perl(:MODULE_COMPAT_%(eval "`%{__perl} -V:version`"; echo $version))' can be used and you're right. Let's go with that for now.

From FPG:  

"Some packages link to libperl.so, usually to provide embedded Perl functionality. All of these packages must also use the versioned MODULE_COMPAT dependency, because the automatically generated dependency on libperl.so does not include any interface version number."

This kind of forgets that unversioned libperl.so is only provided by perl-devel -- at the moment.
