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

Dear Monks, i've got such a question... How can i be sure that my code on activeperl runs on perl and vice versa? And what can i do to make some perlcodes to run on activeperl? Thnx a lot for your answers in advance!

    In general, it's the other way round you need to worry about more: perl on Windows lacks a number of functions that work on Unix (alarm, chroot, etc). However, the most important things to consider in making a script written on Windows work on Unix are when you interact with the system, either directly (using system or backticks), or indirectly (when manipulating files). Some general guidelines:

    • Avoid system unless you want the user to have to install Unxutils or similar.
    • Be careful with newlines: text files end in CRLF under Windows, but just LF under Unix.
    • Use File::Spec, File::Temp and friends to construct paths and filenames portably.
    • Know that unlink doesn't necessarily delete a file completely under Unix.
    • Don't use Win32 modules, for obvious reasons.

    Howdy!

    You'll need access to systems running Perl other than ActiveState. You could try a CygWin environment on Windows, as well as Perl on Unix based systems.

    Also, look at the perlport man page.

    Bro. Herveus is correct. You might also want to peruse the perldoc perlport manuscripts...

    The only way to be sure is to actually try and run your script on both platforms. Even then, some win32 versions will run a script, but others won't. There is a big difference in the way ActiveState runs on win95/98/ME and later versions like XP. So you really can't be sure things will run cross-platform without extensive testing, on a variety of systems. Of course, the simpler the script, the better the cross-platform compatibility.

    vmware is great for cross platform development of all flavors.
