我对编译最新版本的 XNU 内核的最佳方式有点困惑。我已经看到很多 Mac OS X 10.4 附带的旧内核的说明，但新的来源缺少说明中包含的很多内容。只是make在 XNU 内核源上运行会带来很多关于找不到的错误ctfconvert，ctfmerge并且ctfdump. 有没有人有一个很好的“howto”来构建一个新的内核？

威利的一本新书在第 9 章详细介绍了完整的操作指南。
尝试这个：
#
# Getting C++ filter
#
$ curl http://opensource.apple.com/tarballs/cxxfilt/cxxfilt-9.tar.gz > cxx.tar.gz
$ tar xvf cxx.tar.gz
$ cd cxxfilt-9
$ mkdir -p build obj sym
$ make install RC_ARCHS="i386 x86_64" RC_CFLAGS="-arch i386 -arch x86_64 -pipe" \
RC_OS=macos RC_RELEASE=Lion SRCROOT=$PWD OBJROOT=$PWD/obj \ SYMROOT=$PWD/sym DSTROOT=$PWD/build
#
# Getting DTrace – This is required for ctfconvert, a kernel build tool
#
$ curl http://opensource.apple.com/tarballs/dtrace/dtrace-90.tar.gz > dt.tar.gz
$ tar zxvf dt.tar.gz
$ cd dtrace-90
$ mkdir -p obj sym dst
$ xcodebuild install -target ctfconvert -target ctfdump -target ctfmerge \ ARCHS="i386 x86_64" SRCROOT=$PWD OBJROOT=$PWD/obj SYMROOT=$PWD/sym \ DSTROOT=$PWD/dst
#
# Getting Kext Tools
#
$ wget http://opensource.apple.com/tarballs/Kext_tools/Kext_tools-180.2.1.tar.gz \ > kt.tar.gz
$ tar xvf kt.tar.gz
$ cd Kext_tools-180.2.1
$ mkdir -p obj sym dst
$ xcodebuild install -target Kextsymboltool -target setsegname \ ARCHS="i386 x86_64" SRCROOT=$PWD OBJROOT=$PWD/obj SYMROOT=$PWD/sym \
DSTROOT=$PWD/dst
#
# Getting Bootstrap commands – newer versions are available, but would # force xcodebuild
#
$ curl http://opensource.apple.com/tarballs/bootstrap_cmds/bootstrap_cmds-72.tar.gz \ > bc.tar.gz
$ tar zxvf bc.tar.gz
$ cd bootstrap_cmds-84
$ mkdir -p obj sym dst
$ make install RC_ARCHS="i386" RC_CFLAGS="-arch i386 -pipe" RC_OS=macos \
RC_RELEASE=Lion SRCROOT=$PWD OBJROOT=$PWD/obj SYMROOT=$PWD/sym DSTROOT=$PWD/dst
tar 球版本现在不同（例如 DTrace 是 96，而不是 90），但这应该可以满足依赖关系。一旦你有了它们，你只需运行通常的 make (make ARCH_CONFIGS=" X86_64" KERNEL_CONFIGS="RELEASE")。您可能需要添加DEBUG, 以获取默认禁用的出色调试和跟踪消息。
这适用于 XCode 4.4。现在才试了一下，真的。

我认为这不适用于 Lion 内核，它需要更高版本的 XCode，但我在构建 10.6.8 内核时解决 ctf* 错误的方法是使用 XCode 3.2。*
ctf* 二进制文件是在“dtrace”编译期间创建的。
只需从没有任何空格的目录中运行此脚本（例如 ~/xnu 就完美了）。最终结果应该是一个工作的 10.6.8 内核。较晚的（实际上更早的）内核都比 10.6.8 简单。
#!/usr/bin/env bash
# Builds 10.6.8 kernel - most other builds are easier, this one needs a little patching.
# Script assembled by sfinktah
# Invaluable source: slice - http://www.projectosx.com/forum/lofiversion/index.php/t1922.html
# Note, two (got this down to one) patches necessary to build 10.6.8 - source: http://www.insanelymac.com/forum/index.php?showtopic=261736
# This is automatically applied, but I will detail here:
#
# You will have to do this: (Automated now, but just in case)
# Define CPUFAMILY_INTEL_SANDYBRIDGE in ~/xnu-1504.15.3/osfmk/mach/machine.h
# #define CPUFAMILY_INTEL_SANDYBRIDGE 0x5490b78c
#
# Skipped this step, seemed not to be needed (eventually). Leaving notes in, just in case.
# Add line 1 in ~/xnu-1504.15.3/makedefs/MakeInc.def:
# export BUILD_STABS = 1
#
# You should probaby use a local proxy, since this script makes no effort not to redownload
# existing items. Uncomment this line accordingly.
# export http_proxy=192.168.1.6:3128
export PATH="/usr/local/bin:$PATH"
