CPAN modules to RPMs

by clueless newbie (Deacon)
on May 11, 2018 at 15:15 UTC ( #1214386=perlquestion: print w/replies, xml ) Need Help??

clueless newbie has asked for the wisdom of the Perl Monks concerning the following question:

I am faced with the tasks of creating RPMs from CPAN modules.

Research indicates:
A tutorial Build RPMs of CPAN Modules
A side share Perl in RPM land - slide share
A module Module to assist in converting CPAN modules to RPM
An app App to create RPM from CPAN modules
And a repository RPMPAN but it gives me the impression of not having been updated in a some time.

For those of you who do create RPM from cpan modules would you share your experiences and wisdom please?

Many thanks.

    There are really only two supported ways to make RPMs (not counting manually creating the spec file, etc.). cpanspec (see your first link) and cpantorpm. cpanspec is good, but has some problems (it hardcodes some redhat specific stuff, and it tries to parse the Makefile.PL/Build.PL files which is fine if they follow strict conventions, but I didn't like that assumption), so I wrote cpantorpm. You can read more details about why I wrote it here. Have you tried to use it? It's got a lot of options, but if you have any questions, feel free to toss them out and I'll try to respond. It'll do everything that cpanspec and cpan2rpm (an older tool which hasn't gotten much support in a long time) will do, doesn't care what rpm based distribution you're on (I use it on both OpenSuSE and Redhat), and I've built hundreds of RPMs with it.
      Hi, SBECK, Trying CPANtoRPM on a Centos 7 (Perl version 5.16.3). I assume "rpmbuild" would be the packager so I using
      cpantorpm -n -p rpmbuild App::CPANtoRPM
      This yields:

      Could you tell me what I'm doing wrong?

      Many thanks!

    Years ago i used Alien. Sometimes it worked fine and sometimes not. Today i would give cpantorpm by Sully a try. Yet another tool i didn't know. I wonder why he didn't write it earlier ;-). See also. Best regards, Karl

    Minor update: Fixed bad denglish.

    «The Crux of the Biscuit is the Apostrophe»

    perl -MCrypt::CBC -E 'say Crypt::CBC->new(-key=>'kgb',-cipher=>"Blowfish")->decrypt_hex($ENV{KARL});'Help

      I wrote (and released) it 6 years ago... but it hasn't gotten any publicity. That's probably my fault... I never do much to promote any of the modules I've written. I've been using cpantorpm regularly for those years.
        "...probably my fault..."

        Yes. Now become a better person ;-)

        Many thanks and best regards, Karl

Re: CPAN modules to RPMs

    My knee-jerk approach to a Perl problem is to find a CPAN module to do what I want. When choosing between CPAN modules the rule of thumb in the absence of other information is to go with the most recent.

    I have no recent experience with this, but I can tell you that in 2007 (as nearly as I can reconstruct) cpan2rpm (your Module to assist in converting CPAN modules to RPM) was badly broken. Specifically, it assumed things were in distributions they were no longer in, and would not even install on a then-recent Perl. If you got past that, it died trying to process packages that built using Build.PL, even if there was a Makefile.PL present.

    A development release has been made since then (in 2012), but no production release. It looks like the dependency problems have been fixed, but I can not say about the Build.PL problem.

    On the other hand, Sullivan Beck's App-CPANtoRPM was released last month, so that is where I would start.

      A minor clarification... App-CPANtoRPM was first released in 2012 (the most recent release was a month ago). So, though it's never gotten a lot of publicity, I have been refining it and working the bugs out for 6 years. The syntax and functionality were heavily inspired by cpan2rpm (as a matter of fact, I spent a good while trying to fix cpan2rpm before abandoning that line in favor of a complete rewrite), so I owe a lot of thanks to cpan2rpm.
