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.	[reply] [d/l] [select]

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. yours, Michael	[reply]

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

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.	[reply]
