On a Linux host the driver sets the environment of the scripts/linux/setup-toolchain.py toolchain: the xcrun shim answers SDK queries with the build tree's fakeroot, clang targets plain arm64 for iOS 17, and CCC_OVERRIDE_OPTIONS turns off two warnings upstream clang has and Apple clang does not (the archive builders use -Werror and replay xnu's compile records, so only the clang driver sees them). - build-xnu-4k-baseline.sh runs scripts/linux/prepare-xnu.py: source rewrites the xnu sources that assume Apple's tools (SHA/AES assembler macros, makesyscalls.sh under mawk, kextsymboltool and /dev/null) and installs TargetConditionals.h into the fakeroot; libs builds libcc_kext.a from compiler-rt's cc_kext profile sources. xnu's make also gets the host compiler, mig and the machine sizes a Mac supplies. ditto becomes cp. - build-firehose.sh compiles libfirehose_kernel from its xcconfig. - build-corecrypto-14.py reads project.pbxproj with scripts/pbxproj.py (same JSON as plutil for all 13,112 objects). - The kernelcache is decoded with lzfse. The macOS path is unchanged apart from ditto. Built from the same sources and configuration on Linux and with Xcode 27.1, the kernels have the same global symbols, linked objects, archive symbols, 1,265 kalloc_type signatures, and prelink bindings and kexts.

/* <TargetConditionals.h> for the UniXNU kernel step on Linux (scripts/linux/prepare-xnu.py installs it).
|
|
*
|
|
* On a Mac this header comes from the iPhoneOS SDK's usr/include. xnu itself skips it under
|
|
* XNU_KERNEL_PRIVATE; what includes it is code built against Kernel.framework from outside xnu
|
|
* (libfirehose_kernel, the kext-style archives). The TARGET_OS_* values are derived from the
|
|
* compiler's target triple, as the SDK header does, so an arm64-apple-ios17.0 compile sees iOS.
|
|
* Clang predefines most TARGET_OS_* for Darwin targets itself; each one here applies only when
|
|
* the compiler did not.
