Re: CPAN module for prime factors of a number

Have you seen Math::Pari::factorint?

I would use that, but I want to use it as a dependency for a module that will go on CPAN. How does CPAN cope with external dependencies such as pari/gp because Math::Pari is only an interface to pari/gp which needs to be installed. Looking forward to your oppinion about this , thanks :)	[reply]

If you install Math::Pari using the cpan shell, it offers to fetch and build Pari/GP for you. That's no guarentee the build will succeed--it fails on my Win64 system--but should work most places I think.

Twice in one day, still not getting the hang of reading the documentation I see :) It's a good habit that will save you time.	[reply]

Math::Pari is only an interface to pari/gp which needs to be installed All you need do is install the Math::Pari module. To do that, you will need to grab the pari source, but you don't have to build GP/PARI - see the instructions at http://cpansearch.perl.org/src/ILYAZ/Math-Pari-2.01080603/INSTALL. Last time I tried, Math::Pari wouldn't build with the pari-2.3.4 source, so (I think) I used the pari-2.1.7 source, which was fine. Perhaps that has changed with latest Math::Pari releases - last version I built was 2.010800. Cheers, Rob	[reply]
