Hello,

thank you for all your links. They were very interesting. In the meantime I tried cava packager which is also a good packaging tool.

But I like it to solve problems. And I like the one file concept of pp and so I did not give up. And now I have found the complete solution.

1. pp -p -B -o packed_script.par main_script.pl helper_script.pl

2. Add the file "main.pl" to "packed_script.par" in the script folder where now also are "main_script.pl" and "helper_script.pl".

   main.pl

   if (defined $ENV{PAR_APP_REUSE}) {
       my $filename = $ENV{PAR_APP_REUSE};
       delete $ENV{PAR_APP_REUSE};
       $ENV{PAR_0} = $filename;
   
       PAR::_run_external_file($filename, 1);
       exit();
   }
   
   
   my $zip = $PAR::LibCache{$ENV{PAR_PROGNAME}} || Archive::Zip->new(__FI
   +LE__);
   my $member = eval { $zip->memberNamed('script/main_script.pl') }
           or die qq(main.pl: Can't open perl script "script/main_script.
   +pl": No such file or directory ($zip));
   
   PAR::_run_member($member, 1);

3. pp -o  packed_script --reusable packed_script.par

Here how to call the external helper script from the main script:

#############################################################
# part in the main_script.pl where the helper script is invoked
#############################################################

my $cmd;
if( defined $ENV{PAR_TEMP} )
{
    $cmd = "$0 --par-options --reuse $ENV{PAR_TEMP}/inc/script/helper_
+script.pl";
}
else
{
    $cmd = "perl helper_script.pl";
}

# invoke cmd

Now the main script and another external script "helper_script.pl" are packed in one standalone executable. It is running without the need of a perl installation. And all needed modules are packed.

Feedback to this solution is welcome.

Cheers, Dirk
