scripts/linux/setup-toolchain.py, run once as root, builds into /opt/unixnu-linux (or PREFIX, or $UNIXNU_TOOLCHAIN): - clang from llvm-project 58c46bae2118 with llvm-xnu-builtin-type.patch, which adds __builtin_xnu_type_signature, __builtin_xnu_type_summary, __builtin_xnu_types_compatible and xnu_usage_semantics; kalloc.h uses the builtins with no fallback; - cctools-port 1030.6.3-ld64-956.6 (its master, ld64-609, corrupts the kernel link), with libdispatch for ld64; - mig and migcom from bootstrap_cmds-138; - iig-port, with iig-port-darwin-target.patch; - xnu-host-cc, the host compiler for xnu's SETUP tools; - lzfse for the kernelcache. It installs the Command Line Tools shims (clang, clang++, cc, install, gm4) under the prefix and xcrun, plutil and codesign in /usr/bin, where xnu's makefiles call them. libmacho.a and libstuff.a go to /usr/lib and libdispatch to /usr/local. Each step is skipped when its output exists. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# xcrun(1) shim for building XNU on Linux.
|
|
#
|
|
# xnu's makedefs call `xcrun -sdk <sdk> -find <tool>` for every tool and
|
|
# `xcrun -sdk <sdk> -show-sdk-path|-show-sdk-version|-show-sdk-platform-path`
|
|
# to resolve the SDK. On Linux there is no Xcode, so:
|
|
#
|
|
# * `-find TOOL` resolves TOOL against the directories in $XNU_TOOLCHAIN_BIN
|
|
# first (the Command Line Tools' usr/bin, where setup-toolchain.py
|
|
# installs the Mach-O tools, mig and the clang wrappers, then the Xcode
|
|
# toolchain's usr/bin, where it installs iig, as on a Mac), then against
|
|
# $PATH. Unknown tools print
|
|
# nothing and exit 1, which is what makedefs expects for the optional ones
|
|
# (ctfconvert, scan-build, docc...).
|
|
# * `-show-sdk-path` echoes $UNIXNU_SDKROOT, which the driver points at the
|
|
# build tree's fakeroot, so every $(SDKROOT)/... path in MakeInc.def lands
|
|
# there.
|
|
#
|
|
# Everything else is passed through: `xcrun [-sdk X] cmd args...` execs cmd.
