g0177325 has asked for the wisdom of the Perl Monks concerning the following question:

Hi - I'm using the 32 bit portable install of Strawberry Perl 5.16.3 (also tried 5.18.0.1) on Windows 7 x64. I installed PAR::Packer manually by downloading the zip bundles for PAR::Packer and it's two dependent modules Getopt::Argvfile and Module-Scandeps, and building them the standard way (perl Makefile.pl; dmake test; dmake install). All tests passed.

I then try: pp -v -o tt.exe -e "print 1..99"

I see a bunch of modules that presumably PAR needs to do its thing, and the tt.exe files is 3.5 MB, which is reasonable. Opening it with winzip shows only 5 files. So far so good.

Next I try: pp -v -o ttt.exe -e "use strict; print 1..99"

This takes 10 times longer than the first one, I see the same modules needed by PAR being included, but the ttt.exe file is over 9 MB, and winzip shows over 1500 files in it!

Why is PAR including many modules that it doesn't need at all? Things like DBD, DBI, CPAN, Tar, etc. This makes no sense to me at all.

Re: PAR::Packer pp command including too many modules

    Why is PAR including many modules that it doesn't need at all?

    Well, because scandeps thinks it needs those modules ... scandeps decides

    Things like DBD, DBI, CPAN, Tar, etc.

    Um, scandeps.pl went nuts?

    Which version of PAR/Module::ScanDeps did you install?

    ? What is the output of perl -V

    ? What is the output of  pp -v -o ttt.exe -e "use strict; print 1..99"
