I am using Xcode 15.2 Beta on macOS Sonoma 14.3 Beta with the macOS Sonoma 14.2 SDK. Similarly to post 702244, I am trying to build the same exact repository, partially for my own education. The issue I am running into is that one of the files references IOKit/hid/IOHIDDevice.h, which, in turn, references IOKit/IOReporter.h. Since both of these are searched for, with #include <…>, in a base path of Kernel.framework/Versions/A/Headers, it follows that there should at least be a file somewhere in that folder called IOReporter.h, but there is not. There isn't even a copy in IOKit.framework/Versions/A/Headers, although that folder has another version of hid/IOHIDDevice.h entirely, which does not reference a IOReporter.h file. Is the lack of an IOReporter.h file deliberate, accidental, or is the mere continued existence of a kernel-space IOKit IOHIDDevice.h, containing a deprecated kernel-space IOHIDDevice symbol, an accident; possibly a simple hold-over from a previous version? Is there a way to make this compile? Am I missing anything? Should it be assumed that deprecated kernel-mode APIs will simply not compile?
