相信Pluto项目的z3导入问题一定挡住了很多想为NDK集成Pluto的人
Ubuntu版本 22.04.5 ndk版本 r25c
安装编译所需环境
1 | sudo apt install -y vim git build-essential clang clangd bison flex libz3-dev rsync python3 python-is-python3 python3-pip unzip cmake ninja-build |
按照这篇文章里的步骤把r25c的repo sync下来 https://bbs.kanxue.com/thread-271271.htm
编译
1 | python toolchain/llvm_android/build.py --no-build windows,lldb --skip-tests |
复制Pluto的整个 llvm/lib/Transforms/Obfuscation/ 目录 和 llvm/include/Transforms/Obfuscation/目录到源码中
修改 llvm/lib/Transforms/Obfuscation/CMakeLists.txt
下载z3的linux预编译包，把so加入链接，配置include_path，一定要绝对路径
# Set custom Z3 paths
set(Z3_INCLUDE_DIR "/home/xxx/ndk_obfu/z3/z3-4.14.0-x64-glibc-2.35/include")
set(Z3_LIBRARIES "/home/xxx/ndk_obfu/z3/z3-4.14.0-x64-glibc-2.35/bin/libz3.so")
# Include Z3 headers
include_directories(${Z3_INCLUDE_DIR})
add_llvm_component_library(LLVMObfuscation
HelloWorld.cpp
CryptoUtils.cpp
Flattening.cpp
MBAUtils.cpp
MBAObfuscation.cpp
Substitution.cpp
IndirectCall.cpp
BogusControlFlow.cpp
GlobalEncryption.cpp
Pipeline.cpp
LINK_COMPONENTS

Support
Analysis
TransformUtils
LINK_LIBS
${Z3_LIBRARIES}

打开 toolchain/llvm_android/do_build.py，注释874-882行（删除test流程）
再次编译
1 | python toolchain/llvm_android/build.py --no-build windows,lldb --skip-tests |
编译完成后打包 out/install/linux-x86/clang-dev
复制并替换原来ndk中的bin目录
1 | cp -rf ~/ndk_obfu/clang-dev/bin/* ~/ndk_obfu/android-ndk-r25c/toolchains/llvm/prebuilt/linux-x86_64/bin/ |
编译测试，输出如下代表成功
