Hello,
This is weird. For the native library, I use @executable_path in the
attribute and it works both in non-bundled and bundled version.
Have you tried to get the executable path in both version to decide what to
put in the attribute ? To get the "real" executable path, you can use the
snippet of code found the ObjectiveCRuntime.MainBundlePath property (base on
_NSGetExecutablePath native call).
Regards, Laurent Etiemble.
