I'm sorry and do apologize: The above was not at all helpful.

'dir' _is_ the first argument of
package_native_routine_registration_skeleton()  and the error
message showed another function (with a similarly much much much
too long name, so nobody reads the name to an end).

Indeed, I get the same message as you when I use this on a
source package directory... though one that does already contain
everything perfect in the init.c file.

So maybe the function should not give an error but just
acknowledge that no *unregisterted* native symbols were found ?
