xcode9.2 集成obfuscator-llvm-6.0.0

一、理论基础

1、iOS Hacker obfuscator-llvm Xcode集成配置

https://m.aliyun.com/jiaocheng/353659.html?spm=5176.100034.3.1.4f171a01rmKmoP

2、obfuscator-llvm/obfuscator

https://github.com/obfuscator-llvm/obfuscator/wiki/Installation

3、obfuscator-llvm-6.0.0:

https://github.com/spelle/obfuscator/tree/llvm-6.0.0

二、方法步骤

1.下载代码

git clone https://github.com/spelle/obfuscator obfuscator.src

cd obfuscator.src

git checkout llvm-6.0.0

2.准备编译环境并编译

Retrieve dependencies：

curl -E -fsSL http://releases.llvm.org/6.0.0/cfe-6.0.0.src.tar.xz -o cfe-6.0.0.src.tar.xz && \

curl -E -fsSL http://releases.llvm.org/6.0.0/compiler-rt-6.0.0.src.tar.xz -o compiler-rt-6.0.0.src.tar.xz && \

curl -E -fsSL http://releases.llvm.org/6.0.0/libcxx-6.0.0.src.tar.xz -o libcxx-6.0.0.src.tar.xz && \

curl -E -fsSL http://releases.llvm.org/6.0.0/libcxxabi-6.0.0.src.tar.xz -o libcxxabi-6.0.0.src.tar.xz && \

curl -E -fsSL http://releases.llvm.org/6.0.0/libunwind-6.0.0.src.tar.xz -o libunwind-6.0.0.src.tar.xz && \

curl -E -fsSL http://releases.llvm.org/6.0.0/lld-6.0.0.src.tar.xz -o lld-6.0.0.src.tar.xz && \

curl -E -fsSL http://releases.llvm.org/6.0.0/lldb-6.0.0.src.tar.xz -o lldb-6.0.0.src.tar.xz && \

curl -E -fsSL http://releases.llvm.org/6.0.0/openmp-6.0.0.src.tar.xz -o openmp-6.0.0.src.tar.xz && \

curl -E -fsSL http://releases.llvm.org/6.0.0/polly-6.0.0.src.tar.xz  -o polly-6.0.0.src.tar.xz && \

curl -E -fsSL http://releases.llvm.org/6.0.0/clang-tools-extra-6.0.0.src.tar.xz -o clang-tools-extra-6.0.0.src.tar.xz && \

curl -E -fsSL http://releases.llvm.org/6.0.0/test-suite-6.0.0.src.tar.xz -o test-suite-6.0.0.src.tar.xz && \

for f in $(ls *.tar.xz) ; do tar xf $f ; done

Create links for projects：

cd obfuscator.src && \

cd projects && \

ln -snf ../../compiler-rt-6.0.0.src compiler-rt && \

ln -snf ../../libcxx-6.0.0.src libcxx && \

ln -snf ../../libcxxabi-6.0.0.src libcxxabi && \

ln -snf ../../libunwind-6.0.0.src libunwind && \

ln -snf ../../openmp-6.0.0.src openmp && \

ln -snf ../../test-suite-6.0.0.src test-suite && \

cd ..

Create links for tools：

cd tools && \

ln -snf ../../cfe-6.0.0.src clang && \

ln -snf ../../lld-6.0.0.src lld && \

ln -snf ../../lldb-6.0.0.src lldb && \

ln -snf ../../polly-6.0.0.src polly && \

cd clang && \

cd tools && \

ln -snf ../../clang-tools-extra-6.0.0.src extra && \

cd .. && \

cd .. && \

cd .. && \

cd ..

Launch the build：

cd build

mkdir buildcmake -G "Unix Makefiles" -DLLDB_CODESIGN_IDENTITY='' ../obfuscator.src  (如果此处报错，找不到swig，则按照之 brew install swig)

make -j7

三、集成到xcode9.2

1.编写xcode插件

$ cd /Applications/Xcode.app/Contents/PlugIns/Xcode3Core.ideplugin/Contents/SharedSupport/Developer/Library/Xcode/Plug-ins/

$ sudo cp -r Clang\ LLVM\ 1.0.xcplugin/ Obfuscator.xcplugin

$ cd Obfuscator.xcplugin/Contents/

$ sudo plutil -convert xml1 Info.plist

$ sudo vim Info.plist

Change:

<string>com.apple.compilers.clang</string> -> <string>com.apple.compilers.obfuscator</string>

<string>Clang LLVM 1.0 Compiler Xcode Plug-in</string> -> <string>Obfuscator Xcode Plug-in</string>

Then:

$ sudo plutil -convert binary1 Info.plist

$ cd Resources/

$ sudo mv Clang\ LLVM\ 1.0.xcspec Obfuscator.xcspec

$ sudo vim Obfuscator.xcspec

Change:

<key>Description</key>

<string>Apple LLVM 9.0 compiler</string> -> <string>Obfuscator 6.0 compiler</string>

<key>ExecPath</key>

<string>clang</string> -> <string>/path/to/obfuscator_bin/clang</string>

<key>Identifier</key>

<string>com.apple.compilers.llvm.clang.1_0</string> -> <string>com.apple.compilers.llvm.obfuscator.4_0</string>

<key>Name</key>

<string>Apple LLVM 9.0</string> -> <string>Obfuscator 6.0</string>

<key>Vendor</key>

<string>Apple</string> -> <string>HEIG-VD</string>

<key>Version</key>

<string>9.0</string> -> <string>6.0</string>

Then:

$ cd English.lproj/

$ sudo mv Apple\ LLVM\ 9.0.strings "Obfuscator 6.0.strings"

$ sudo plutil -convert xml1 Obfuscator\ 6.0.strings

$ sudo vim Obfuscator\ 6.0.strings

Change:

<key>Description</key>

<string>Apple LLVM 9.0 compiler</string> -> <string>Obfuscator 6.0 compiler</string>

<key>Name</key>

<string>Apple LLVM 9.0</string> -> <string>Obfuscator 6.0</string>

<key>Vendor</key>

<string>Apple</string> -> <string>HEIG-VD</string>

<key>Version</key>

<string>9.0</string> -> <string>6.0</string>

Then:

$ sudo plutil -convert binary1 Obfuscator\ 6.0.strings

2.xcode配置

先重启xcode，已加载新创建的插件

设置obfuscator混淆器，如下图：

然后就可以正常编译工程，打包上传到App Store了。

四、问题

xcode连接真机运行时，报错cannot specify -o when generating multiple output files，解决方法：Build Setting 中搜索 Index-While-Building 设置为 NO 可编译成功。
