This seems to be an issue with the swig3 preprocessor, when I add

#define OC_NONNULL(...)

to an .i file and include a .h file which uses the macro. This works fine:

int oc_str_to_uuid_v1(const char *str, size_t str_len, oc_uuid_t *uuid)
  OC_NONNULL(1);

but this does not

void oc_gen_uuid(oc_uuid_t *uuid) OC_NONNULL();

So the swig3 preprocessor doesn't seem to match the non-parametrized define version, which is a bug I think.

@kevinlab-kskim is update to swig4 not an option?

[Danielius1922]

Last Swig3 release was Jan 2017, so that's more than 7 years old. I think we can declare we only support swig4 and later.
