A zipped bundle app: no executable after unzipping

Hi all
I've a little question for you LC forumers!
Here is my problem: I've a zipped ".app" bundle that I want to extract and execute.
Everything goes well with the extraction as my ".app" bundle file is correctly extracted but when I try to launch it... it doesn't start.
Trying to extract it with system tools it extracts and starts correctly.
So analyzing the bundle after Livecode extraction comparing with the other I can see that the executable file "myapp.app/Contents/MacOS/myapp" has no execution rights. Why this happens? Where am I wrong?!
Thank you for your replies!

What did you use to compress the app?

Hi CoffeeCone
Simply compressed with Mac compress utility.

What's "LiveCode extraction"? Are you trying to extract and launch an app from a compressed archive at runtime from a LiveCode script? If so, how are you doing this? Are you shelling out to the OS or are you using LC's builtin zip or decompress functions?

Yes, I'm trying to do exactly this!
I've a "myapp.zip" containing "myapp.app". When I extract the zip using the built-in LC extracion tools the file "myapp" inside the bundle has no more the "x" attribute.
Anyway I've solved my probs in another way using LC built-in zip function in "Win32" platform, "ditto" command line on "MacOS" and "unzip" under "Linux".
But I think Livecode should preserve the right rights (ops... sorry!) when unzipping...
Thank you for your replies guys!

Aha! Yes, I think you've come across a long-standing bug in the internal libraries regarding the executable bit. Hopefully with the open-source rework this can get fixed up. I do the same thing you do, shelling out to the OS to do zip functions. You'll also find that the internal routines can't handle folders.
But stay tuned - there's lot of fun to come in the next few months.
