I'm packaging a CPAN module PE::Queue and my rpm
builds fine, but 'rpmlint -i
' gives
the following errors:
E: perl-PE-Queue useless-explicit-provides
perl(PE::Kernel)
This package provides 2 times the same capacity. It
should only provide it
once.
E: perl-PE-Queue useless-explicit-provides
perl(PE::Loop::Tk)
This package provides 2 times the same capacity. It
should only provide it
once.
My .spec does not explicitly list the provides; I'm
relying on RPM to find them automatically.
I noticed that 'find /BUILD/PE-0.37 -type f -exec
/usr/lib/rpm/perl.prov {} \; | sort | uniq' lists both
provides with and without a trailing number, as in:
<snip>
perl(PE::Kernel)
perl(PE::Kernel) = 2116
<snip>
perl(PE::Loop::Tk)
perl(PE::Loop::Tk) = 1980
<snip>
No other provide is listed twice, though some list
with trailing numbers (what do they mean?) and some
list without.
Are these errors important? What do I do to make them
go away?
TIA-

rpmlint is complaining about a redundant dependency.

There is a dependency on any perl(PE::Kernel) as well as on a
specific version.

No other provide is listed twice, though some list
with trailing numbers (what do they mean?) and some
list without.

Run
rpm -qp
to find which files are generating the dependencies.

The errors are likely harmless.

Change one of the two "use " statements in the files to be like
the other
so that perl-req.pl extracts one, not two, dependencies.

Alternatively, you can override %__perl_requires with a wrapper
that looks something like this in your spec file:

Source9: myperlrequires.sh

%define __perl_requires%{SURCE9}

and the contents of myperlrequires.sh should look something like
#!/bin/sh
/usr/lib/rpm/perl.req | sed -e 's/perl(PE::Kernel = 2116)//' -e
's/perl(PE::Loop::Tk) = 1980//'

In other words just post process the perl dependency extractor to
remove unwanted dependencies.

Patching the perl scripts is the better fix however.

(all the above is untested, watch for typos)
