Editing Developing and Distributing wxPerl Applications on Windows (section)

=== PAR::Package and WX::Perl::Packager ===

==== Step 1 - Install PAR::Package and Wx::Perl::Packager ====
<code><big>C:\> cpanm --verbose PAR::Package Wx::Perl::Packager</big></code>

==== Step 2 - Generate the EXE ====
Assuming you have a Perl script generated either via wxGlade (see above) or one you have created/updated by hand, the command is as follows:

<code><big>C:\> wxpar YOURPROGRAM.pl -o YOURPROGRAM.exe</big></code>

===== Important Notes About wxGlade Generated Code =====
# earlier versions of wxGlade introduced an improper idiom at the bottom of the generated Perl script that caused a problem when running via a PAR::Packed packed executable. TLDR; remove the "unless(caller)" block and just run the Wx event loop unfettered. For more information, please read the [https://metacpan.org/dist/PAR/view/lib/PAR/FAQ.pod#If-I-try-to-compile-my-wxGlade-generated-script%2C-it-doesn%27t-run.-What%27s-wrong%3F PAR::FAQ.]
# earlier versions of wxGlade also used a non-Exporter import tage that wxpar could not properly follow; see the code "before" and "after" below:

 use Wx qw[:allclasses];
 use strict;
 
 ...
 
 package main;
 
 unless(caller){
     my $local = Wx::Locale->new("English", "en", "en"); # replace with ??
     $local->AddCatalog("app"); # replace with the appropriate catalog name
 
     my $app = MyApp->new();
     $app->MainLoop();
 }
Should be modified to look like the following:
 use Wx qw;
 use strict;
 
 ...
 
 package main;
 
 my $local = Wx::Locale->new("English", "en", "en"); # replace with ??
 $local->AddCatalog("app"); # replace with the appropriate catalog name
 
 my $app = MyApp->new();
 $app->MainLoop();
See [https://github.com/wxGlade/wxGlade/issues/568 this Github issue] for wxGlade, where both were fixed. At the time of this writing, the changes. have not been put out in an official release; but they are applied in the master branch.
