try

otool -L youapp

At least we will now for sure if it links on the static library or something else.

I checked this first thing.

otool -L KosmicQuitter

this looks okay to me.
I added the -search_paths_first linker option without effect.

The error begins /Users/Jonathan/Library/Caches/Cleanup At Startup/..
This is created dynamically it seems.
Could the static library write out a bundle for its own use? Seems strange though could be an anti-tamper measure given the nature of the library.
The error is, in the end, a GC capability mismatch - so maybe the static linking is okay and the dynamic(?) bundle is throwing me off the memory trail.


I will return to examine the apparently working demo.

This my problem. I am only linking to the static Library.

That's obviously what you *want* to do, but the error message you're getting indicates that's not how your app is actually linked. Disbelieving the evidence is usually not an effective debugging technique. :-)


When you link with -l, the linker prefers dynamic libraries over static when both are present. To force static linking, have a look at:
