Internet app - OpenLibrary(dylib) returns 0

Hello,
My software contains a binary file (.app) and a library file (.dylib).
Both are compiled with PB 5.73.
They are signed (with hardened runtime option).
A DMG is made with these files.
The DMG is signed and notarized (with my Apple ID developper)
No problem until now.
The DMG is uploaded on internet.
I download the DMG from internet.
I extract the folder with the app & dylib files.
When i run the app file, there is the following error message "
error loading library 'xxx.dylib !' (means "OpenLibrary() returns 0)'.
Does somebody know what i am missing ?
Some remarks
If i import the same DMG file from my local network (not internet), there is no problem.
The signature check for the dylib file command shows: "Info.plist=not bound".
But in my opinion, it is not possible to embeed a plist file with a dylib file.
The notarization procedure shows this message:
2020-12-04 10:30:41.505 altool[4134:88747] CFURLRequestSetHTTPCookieStorageAcceptPolicy_block_invoke: no longer implemented and should not be called
No errors uploading 'xxxxx.dmg'.
RequestUUID = 16f31155-3115-4468-930e-c0446828b706
But i think this is just a warning not important because the app file works correctly when it is packaged without the dylib file.

Where do you put the DyLib?
It is best to put the own library into the APP package. "MyApp.app/Contents/Library" or "MyApp.app/Contents/Resources".
For this I have written a tool for PB-IDE.

The dylib is presently at same level than the app file/folder.
We were a bit lazy to do this change.
But this time we may not have other choice with the recent new OS "Big Sur".
We will work on that.
Thank you for your answer.

We made an APP package with all files (including the dylib file) into the folder "OurProgram.app/Contents/".
But still same problem: the function OpenLibrary(#PB_Any, "OurPBLibrary.dylib") in the app returns 0.
May be some keys to add in the plist file ?
PS: any example of an app with a PB dylib in would be welcome.

The entire path to the library must be specified.
also copy the library into the App folder Contents/Resources or Contents/Library. Order must be.
Remember: PB-IDE Tool MyAppData
Even if I haven't installed Big Sur yet, it has to be done this way.
Code: Select all
libpath.s = GetLibraryPath() + "OurPBLibrary.dylib"
Debug libpath
lib = OpenLibrary(#PB_Any, libpath)
PathHelper
Code: Select all

I've always used
OpenLibrary(#PB_Any, "mylib.dylib")
and simply placed the .dylib file in myapp.app\Contents\
next to Info.plist and it just works
Has Apple broken all backward compatibility with the latest OS update ?

You can see if this works...
https://reelmedia.org/test/testdll.zip
It contains 2 PB files that were used to make the compiled app and the compiled file to test with.
Running the app should return MessageBox containing "SUM" "10"
Works here on MacOS 10.12, 10.14, 10.15 (I don't have anything higher)

@ mk-soft
Thank you very much for this code.
It works now.
FYI, we were using a relative path to load the library, and it does not work with Big Sur.
It is now ok with an absolute path, whatever is the library location (in folder "library" or at "app" folder level).
Thank you all for your precious help.
