编译XNU内核2050

Question

此问题已从超级用户迁移 ，因为可以在堆栈溢出中回答。 迁移 7年前 。

我对编译最新版本的XNU内核的最佳方法有些困惑。 我已经看到了许多有关Mac OS X 10.4附带的较旧内核的说明，但是较新的源代码缺少很多说明中包含的内容。 仅在XNU内核源代码上运行make会带来很多错误，因为它们找不到ctfconvert ， ctfmerge和ctfdump 。 有没有人有很好的“方法”来构建新内核？

Answer 1

Wiley撰写的新书详细介绍了第9章中的完整操作方法。

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球的版本现在有所不同（例如DTrace是96，而不是90），但这应该可以满足依赖性。 拥有它们后，就可以运行常规的make（make ARCH_CONFIGS=" X86_64" KERNEL_CONFIGS="RELEASE" ）。 您可能想要添加DEBUG ，以获取出色的调试和跟踪消息，这些消息默认情况下处于禁用状态。

这适用于XCode 4.4。 实际上，现在就尝试了。

我认为这不适用于Lion内核，后者需要更高版本的XCode，但是在构建10.6.8内核时，我解决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是完美的）。 最终结果应该是运行正常的10.6.8内核。 较新的（实际上是较早的）内核都比10.6.8更简单。

#!/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"
