我對編譯最新版本的XNU內核的最佳方式感到困惑。我已經看到許多關於Mac OS X 10.4附帶的較舊內核的說明,但較新的源代碼缺少很多說明中包含的內容。在XNU內核源代碼上運行make
會帶來很多關於找不到ctfconvert
,ctfmerge
和ctfdump
的錯誤。有沒有人有一個很好的「如何」來構建一個新的內核?編譯XNU內核2050

我不認爲這將適用於Lion內核,它需要更高版本的XCode,但是我在構建10.6.8內核時遇到ctf *錯誤的方式是使用XCode 3.2。*
ctf *二進制文件是在「dtrace」編譯過程中創建的。
只需從一個目錄中運行這個腳本而沒有任何空格(例如〜/ xnu是完美的)。最終結果應該是一個工作的10.6.8內核。後來的(甚至更早的)內核都比10.6.8簡單。
#!/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

一本新書by Wiley詳細介紹了一套完整的操作方法在第9章
試試這個:
#
# 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
焦油球版本現在是不同的(如DTrace是96,不是90),但這應該可以滿足依賴關係。一旦你有他們,你只是運行通常的做法(使ARCH_CONFIGS=" X86_64" KERNEL_CONFIGS="RELEASE"
)。您可能需要添加DEBUG
,以獲取默認禁用的優秀調試和跟蹤消息。
這適用於XCode 4.4。實際上,現在就試過了。
