Re: buildpacked.pl - Pack script and dependencies into self-extracting bash script

[Anonymous Monk]

Congratulations, you've reinvented shar/ fatpack

Congratulations, pp --perlscript can almost do that too :) provided you use -X coremod to exclude core modules

system qw{
pp 
-M Data::Dump::FilterContext
-M Data::Dump::Filtered
-M Data::Dump

-X File::Glob
-X threads
-X Symbol
-X subs
-X overload
-X Exporter
-X vars
-X utf8
-X strict
-X base
-X Carp
-X Config
-X Exporter::Heavy
-X feature
-X XSLoader
-X DynaLoader
-X Scalar::Util
-X mro
-X warnings::register
-X integer
-X warnings
-X MIME::Base64
-X Text::ParseWords
-X List::Util


-C CACHEFILE

--perlscript
-o ddvars
-e } => 'use Data::Dump; dd\@INC,\%ENV; ';

Sure various lib/unicore/lib/IDC/N.pl get packed as well, but no binary components get packed, no .dll's or .so's

[Anonymous Monk]

So here is my version :)

#!/usr/bin/perl --
use strict; use warnings;
use Data::Dump;
use Module::Corelist;

@ARGV or die "Usage: $0   outfile    infile infile infile\n";

my $outfile = shift        || 'ddname';
my @script  = @ARGV ? @ARGV : qw[ dd-inc.pl ];
my @cache   = qw[ -C CACHEFILE ];

my %exclude; # we don't pack core modules available in this perl
my %include;

for ( qx[scandeps @cache -B -V @script ] ){
    /^'([^']+)'/ or next;
    my $mod = $1;
    
    my $first   = Module::CoreList->first_release($mod);
    my $removed = Module::CoreList->removed_from($mod);
    
    $exclude{$mod}++ if defined $first   and $first < $]   ; # core in
+ this perl
    $include{$mod}++ if defined $removed and $] >= $removed; # removed
+ (not core) in this perl
}

my @exclude = map {; '-X', $_ } keys %exclude;
my @include = map {; '-M', $_ } keys %include;

#~ my @args = ( qw[ pp --perlscript --output ] => $outfile, @exclude, 
+@include, @script );
my @args = ( qw[ pp -P -o ] => $outfile, @exclude, @include, @script )
+;
dd \@args;
system @args;

__END__

Impressive coding and deft manipulation - nicely done. I downloaded it and tweaked it to actually run (a typo and Dump->Dumper, print Dumper instead of dd, etc) - nicely done indeed.

However, the resulting file from PAR still gives an error when run on another machine:

Can't locate PAR/Heavy.pm in @INC (@INC contains: ...snip...) at /usr/bin/par.pl line 348.

I even attempted to force inclusion of PAR::Heavy by adding push @include, qw(-M PAR::Heavy); after my @include (Admittedly, I gave up after a few moments of it not working - I didn't try *too* hard) - unfortunately, that didn't change the error message on the other machine at all.

Well it does require PAR to be installed on the other machine :/

[jbryan]

Ahh, so is that different than what the following does:

# From http://search.cpan.org/~rschupp/PAR-Packer-1.013/lib/pp.pm:
    % pp -P -o out.pl file   
    % pp -B -p -o out.pl file  

Neither of the resulting files would run cross-platform (e.g. when copied from 64bit laptop to 64bit machine, both running CentOS, or the other way around - 32bit to 64bit.) Even though no .so/etc were copied, the header on the file that PAR added require'd DynaLoader, which caused it to fail with an error like Undefined subroutine &DynaLoader::bootstrap called at /usr/lib64/perl5/XSLoader.pm line 111. (This is from a file generated with pp on my 64bit laptop last night and ran on my 32bit desktop here at the office.)

I spent several hours googling and trying various options, though I admit I didn't try that -X option (must have glossed over that thru my sleep-deprived hazy vision!)
