On second thought, #731 probably only applies to `rustc` native flags only, rather than those that are passed to the linker (e.g. if I pass a dummy flag, it is passed as-is, so I doubt they will start checking, and probably they shouldn't), so it may not help here after all. > So if I understand what you mean correctly, with this: > KBUILD_PROCMACROLDFLAGS := $(HOSTLDFLAGS) $(PROCMACROLDFLAGS) > Android might need a separate mechanism (another variable?) to filter > out our -L/-Wl,-rpath from HOSTLDFLAGS. (Dumb question: We can't take > -L/-Wl,-rpath away by prepending/appending more flags, right?) Yeah, we would need a variable to provide the filters, but it would be more complex and possibly less flexible. I think it may be best to keep things simple and use the v3 here, which already works for your use case. Cheers, Miguel
