Re: rpmbuild

[Patrick Dupre]

Thank you for these details.
However
1) I expect that I would have to edit the .spec file
2) After that I install the package
perl-Tk-JBrowseEntry-5.22-1.fc30.noarch
I generate a 
perl-Tk-JFileDialog.spec
which contains:
BuildRequires:  perl(Tk::JBrowseEntry) >= 4.63

Why that?
When I want to install
perl-Tk-JFileDialog-2.20-1.fc30.noarch.rpm

I get
Error: 
 Problem: conflicting requests
  - nothing provides perl(Tk::JBrowseEntry) >= 4.63 needed by perl-Tk-JFileDialog-2.20-1.fc30.noarch
(try to add '--skip-broken' to skip uninstallable packages)

The solutions that I found are:
1) add Provides: perl(Tk::JBrowseEntry) = %{version}-%{release}
in perl-Tk-JBrowseEntry.spec
or
2) remove 
BuildRequires:  perl(Tk::JBrowseEntry) >= 4.63
in
perl-Tk-JFileDialog.spec

In my opinion, I should not have to edit the .spec files
