I have an exception running cinterop on an Objective-C library. It is an NSEnum and I tried to specifically import the header file in the def file. What does the exception mean and how can I solve it?

> Task :cinteropRocksdbMacos
Exception in thread "main" java.lang.IllegalArgumentException: 'BlockBasedTableIndexType' from the file package was not reserved for declaration

For reference I used the following def file:

language = Objective-C
headers = ObjectiveRocks.h

I also tried:

language = Objective-C
headers = ObjectiveRocks.h  RocksDBBlockBasedTableOptions.h

I try to include this code: https://github.com/iabudiab/ObjectiveRocks/tree/develop/Code

[Artyom Degtyarev [JB]]

It looks like the ObjectiveRocks.h already has the #import "RocksDBBlockBasedTableOptions.h" line. What do you want to achieve?

[Jurriaan Mous]

It does not work with or without that header. I want it to run the cinterop task without crashing with above message. But I don't understand what 'BlockBasedTableIndexType' from the file package was not reserved for declaration tries to say. It is defined in RocksDBBlockBasedTableOptions.h

Thank you for the details. We had successfully reproduced this behavior, and now we’re investigating its causes. Please wait for updates.

Ah thanks for checking it out! 😄
