Question

我对编译最新版本的XNU内核的最佳方法感到困惑。我已经看到很多关于Mac OS X 10.4附带的旧内核的说明，但是较新的源代码缺少指令所包含的许多内容。只是在XNU内核源上运行make会带来很多关于找不到ctfconvert，ctfmerge和ctfdump的错误。有没有人有一个很好的“howto”来构建一个新内核？

新书by Wiley详细介绍了第9章中的完整操作方法。

试试这个：

#
# 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 ball版本现在不同了（例如DTrace是96，而不是90），但这应该可以满足依赖性。一旦你拥有它们，你就可以运行通常的make（make ARCH_CONFIGS=" X86_64" KERNEL_CONFIGS="RELEASE"）。您可能希望添加DEBUG，以获得默认禁用的优秀调试和跟踪消息。

这适用于XCode 4.4。现在就试试吧。

我不认为这将适用于需要更高版本的XCode的Lion内核，但是在构建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运行此脚本（例如〜/ xnu是完美的）。最终结果应该是一个有效的10.6.8内核。后来（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"
