in reply to perl2exe Evaluation Message Avoider

Well, if that does it, then this would probably be safer:
END { close STDOUT; close STDERR; }

But of course this is untested. I think perl2exe is an abomination and a con.

    Could you elaborate please Merlyn? It seems that the various packagers (perl2exe, AS PerlDevKit, etc) could be useful if you're distributing a perl app in a Win32 environment and want to make sure all modules & versions are correct. AFAIK, perl2exe jsut packages up the perl executable & any code/modules that is required. The packagers also do some obfuscation, but it usually appeared to be very simple.

    There was a discussion of this subject on the boston.pm list recently. What I said above is the gist of what I got from the various replies. I'd love to hear more details.

      In short:
      • perl2exe spits in the face of open source, by allowing a developer to apparently "lock up" the source to a tool that he developed standing on the shoulders of the open source with which he is using.
      • perl2exe puts a separate copy of the libs in each binary, so if someone installs 10 binaries, they get 10 copies of Perl plus 10 copies of any common modules.
      • perl2exe bills itself as a "compiler", which to the innocent masses means "faster" (as wrong as we know that is), and so people get it to "speed up their code".
      It's a con and an abomination. And for a price! That's the worst part.

      I'm working on plans to make an open-source version of perl2exe that bundles the source code of everything a program requires into a single source file. If anyone wants to work with me on that, please contact me by email (not by chatterbox msg). This will be a "compiler" in the sense of "bundler".

        I hadn't thought about the multiple copies for each installation. That could add up in a hurry.

        I agree w/ you 100% about the compiler stuff. We all know there is not a working perl "compiler". I do think we should spread the word that anyone who says they have a compiler is wrong and best, and an out & out liar at worst.

        That said, I'm curious to know more about the Perl DevKit from AS. At the info page http://activestate.com/Products/Perl_Dev_Kit/more_information.plex I see two interesting snippets:

        PerlApp (HP-UX, Linux, Solaris, Windows) - Turn your Perl programs into ready-to-run executables. The PerlApp command-line utility binds Perl scripts and required libraries with a binary loader that runs the script. PerlApp can be used to build dependent applications, which require an existing Perl installation on the target computer, or freestanding applications, which will run on a target computer that does not have Perl installed. The Perl Dev Kit includes versions of PerlApp for HP-UX, Linux, Solaris, and Windows.

        PerlSvc (Windows) - Convert your Perl programs into Windows services. Build dependent services, which require an existing Perl installation on the target computer, or freestanding services, which will run on a target computer that does not have Perl installed. PerlSvc binds the script with a binary loader; the resultant executables run as a service under Windows NT/2000.

        Has anyone used this product to validate either of these claims? I have to admit that it sounds pretty sexy, especially if they build on an AS perl build and will eliminate the duplication of code you mentioned above. And AS has done good things for the perl community in the past so I don't mind giving them my money. Thoughts or experiences anyone?

        I agree that people that use perl2exe to hide their source are cheating the community which donated (on average) half the work.

        However, I do think perl2exe is a necessary program if the community wants to be able to freely distribute Perl code to people without the interpreter.

        IMNSHO: People should offer both source and exe if they are going to offer the exe at all.

        And although I didn't complete that, PAR came into existence to satisfy that very need (and nicely, if I might add).

        Be sure to read my standard disclaimer if this is a reply.

        Well, i had much joy of my registered version! I needed to distribute a (tk/GUI-)perlscript that needed to run on several machines. And installing perl on all win32-machines isn't a good idea and a bit of an overkill.

        Using perl2exe i could distribute the script as a single exe.

        Personally, I feel this thread as a crack-thread because i think, if you really like perl2exe so much, register it. And you should respect this try-ware message.

        If you don't like perl2exe, it's fee or it at all, ignore it, disadvice it, but don't crack it.

    Well... the firs one (with kill) notifies that the process was killed, while with the second solution you have to wait for 2 seconds after the program has finished :-)
    I suppose that if you really want to cover that message in a bit more polite way, maybe try something like this:

    END { print "Cleaning up...\n"; close STDOUT; close STDERR; }

    Normal user would think that it really does something and it's not sleeping any way ;-)
    IMHO the best way to avoid original message is to pay for perl2exe - if you really need it.
