Support for Apple silicon #20

Closed dkocher closed 3 years ago

Dependent on https://github.com/java-native-access/jna/pull/1238

ccidral commented 3 years ago

@dkocher Just curious, were you able to build and use rococoa under Apple silicon? I see that java-native-access/jna#1238 has been closed.

dkocher commented 3 years ago

There are several things to be sorted out

Make sure JNA has no test failures on Apple silicon. See #1323
Always use objc_msgSend on Apple silicon to be patched in MsgSendHandler
Fix several test failures in Rococoa possibly caused by not type safe calling objc_msgSend.

To fix dynamic-dispatching issues in your code, define a type-safe function pointer instead of calling objc_msgSend directly. Refer to Enable Strict Type Enforcement for Dynamic Method Dispatching

Not sure if this is actually an issue with JNA using libffi.

We are making progress.
