Re^4: pp macOS external file

I am a bit confused. The .png file is in the same directory as the executable (I can not have absolute paths, but only relative ones). So, the path for this icon should already be correct (and from the Terminal it works okay). How should the relative path differ in the executable? the OS is darwin.

Added: the problem should be that the executable sees the relative path starting from its "internal" (I do not how to call it) position that a simple:

use File::Basename;
my $dirname= dirname(__FILE__);
[download]

inside my original script reveals to be different than the physical position of the executable on the machine.

"So, the path for this icon should already be correct (and from the Terminal it works okay"

Not when you run it. What follows is a sort of high level explanation of how this works. An executable generated by pp is essentially a self extracting/executing zip file. You can use the normal unzip command to extract it. The first time it executes it gets extracted to a temporary area. For your problem I had:

marto@Shemp:~/perlmonks/pp$ ls
myicon.png  tk.pl
[download]

When packed (as above) and executed this gets extracted to a temporary area, in this case: /tmp/par-6d6172746f/cache-b3da3d80145db3849552916091b87f92bea49883

In the work around above this is accessible via $ENV{PAR_TEMP}. Within this directory you'll find the various bits & bobs, modules, libraries and so on that are required to run your code without needing perl (and all of those other things) installed.

Within this is a directory inc:

drwxr-xr-x  4 marto marto  4096 Apr 20 13:02 .
drwx------  3 marto marto  4096 Apr 20 13:02 ..
drwxr-xr-x 16 marto marto  4096 Apr 20 13:02 lib
-rw-r--r--  1 marto marto  7189 Apr 20 13:02 MANIFEST
-rw-r--r--  1 marto marto   212 Apr 20 13:02 META.yml
-rw-rw-r--  1 marto marto 13052 Apr 20 13:02 myicon.png
drwxr-xr-x  2 marto marto  4096 Apr 20 13:02 script
[download]

here we see myicon.png. the actual script is in the sub directory 'script'. Another method I've seen people use is to embed the images within their code, and use the Tk::Photo -data option (rather than -file).
