Compiled Perlscript hangs on Solaris
Hi all
I have a strange problem with a compiled Perlscript on Solaris 9. After the script is finished it just hangs.
Script looks like this:
#!perl -w
use strict;
use Getopt::Std;
use Date::Manip;
use Mail::Sender;
use Config::General;
use Data::Dumper;
.... Does some stuff (and this behaves as expected)....
print "exiting...\n";
exit 0;
what happens is: It prints "exiting..." and then the prompt just hangs.
Here's the output of perlapp and perl -v:

I think you get the hangs because the PDK is compiling with a different version of libperl.so than your executable uses at runtime.
Here is the telltale:
libperl.so at '/opt/ActivePerl-5.8/lib/5.8.7/sun4-solaris-thread-multi/CORE/libperl.so' is not compatible with the PDK.
Using '/opt/pdk/lib/libperl.so' instead.
The explanation for what is going on comes out of the Release Notes:
The PDK now uses a dynamically linked libperl.so on Unix instead of including statically linked libperl.a in each generated executable. This allowed implementation of the --xclude option for Unix, and --dependent and --xclude applications are much smaller now.
Only libperl.so from ActivePerl 819 and later is fully compatible with the new mechanism. PerlApp will use its own bundled libperl.so for older versions of ActivePerl. It also bundles a special libperl.so to use with Perl 5.6.
Updating to a newer version of ActivePerl would fix the issue. Or you could set PerlApp's --use option to force the executable to use the same libperl.so that it was compiled with, and the odd behavior will probably go away.
Should you consider copying the PDK libperl.so elsewhere, be careful to place it where it won't interfere with the 815 version of libperl.so, or the compatibility problems could go the other way.
