Hello kevbot, that was ist!!! THANK YOU! I have a couple of questions, as I couldn't find any answer on the Wen. 1) Why does it need X11 (if Tkx runs without it without problems)? 2) If I deploy the software to other users... will they need to install X11 to?

Hello Anonymous Monk,

Tk and Tkx are different implementations. Tkx appears to have support for Aqua and/or X11 while Tk requires X11 (see this thread: building Tk without X11 on mac OS).

If you are not using a packager and intend to deploy your script simply by providing a copy of the script, the end users will need to have Xquartz and all required perl modules installed. If you wish to give your users a stand-alone executable, you could try to package up your app using PAR::Packer. This thread (Perl/Tk and PAR::Packer on OS X) has a discussion on trying to create a stand-alone executable of a Perl/Tk app; however, the conclusion seems to be that the end users of the executable would still need to have Xquartz installed.

#!usr/bin/perl
use strict;
use warnings;

I get the same Error with your code (good point to keep it so simple). My code was:

#!/usr/bin/perl -w
# Display Hello World program
        
use Tk;
use strict;
        
my $mw = MainWindow->new;
$mw->geometry("200x100");
$mw->title("Hello World!!!");
        
$mw->Label(-text => 'Hello World')->pack();
        
$mw->Button(-text => "Close", -command =>sub{exit})->pack();
        
MainLoop;

Tk was installed with ppm so I really thought I was on the safe side... but no. Do I have to install codeX to make it run? I do not think is the case. I also tried a mini script with Tkx (which comes with Activestate already installed) and it works fine. What can I try?

I am running a "clean install" of Active State 5.20 for Windows on a laptop - no additional ppm installs. The result is that your script works just fine - no problem. I do not have a Mac, but I've given Tk code before to folks who do and it works fine (although that was before 5.22).

I confess to being flummoxed at this point.

Update: Oh, since latest Mac OS'es are linux like, there may be a path problem between this new latest AS installation and the system's idea of Perl? What does Perl -V show?

dopen: no idea at all!

I wonder if its the "/opt/X11/lib/libX11.6.dylib" library this link could shed some light on your OS X issue. sudo ln -s /opt/X11 /usr/X11

??What is output of ldd -v /Users/xxx/Library/ActivePerl-5.22/lib/auto/Tk/Tk.bundle

?? or otool -L /Users/xxx/Library/ActivePerl-5.22/lib/auto/Tk/Tk.bundle
