Apple SDK Build Issues

[bniladridas]

Summary

The build requires Apple’s internal SDK and a full Xcode installation. The public macOS SDK is insufficient; Apple Developer internal access is required for a complete build.

Build Results

With SDKROOT=macosx.internal:

xcrun: error: SDK "macosx.internal" cannot be located
xcrun: error: unable to find utility "migcom", not a developer tool or in PATH

With SDKROOT=macosx:

xcrun: error: unable to lookup item 'PlatformPath' from command line tools installation
xcrun: error: unable to find utility "migcom", not a developer tool or in PATH
/Users/uploader/Downloads/macos-kernel-dev/xnu/makedefs/MakeInc.kernel:292: *** Could not determine xnu version from SDK or KDK! Set RC_DARWIN_KERNEL_VERSION environment variable. Stop.

Verification

The build issues were verified. Setting RC_DARWIN_KERNEL_VERSION=23.0.0 allows the build to progress past version detection, but it later fails due to the missing availability.pl script in the public SDK.

This confirms that a full kernel build depends on Apple’s internal SDK and tooling.

Resolution

Closed as won’t fix.

A full kernel build requires Apple’s internal SDK and tools, which are not publicly available. The public macOS SDK is insufficient.
