I need to write an XS module for Perl. It is my understanding that h2xs is pretty much deprecated today, what is the preferred method for starting an XS module today? I looked at Module::Starter, but it only handles pure Perl modules.
No, h2xs is not deprecated. Module::Starter is certainly more convenient if you create many pure Perl modules, but there's no reason to avoid h2xs. I would recommend reading all the way through its doc before using it, though, so that you know what all you might want it to do or not do.
