ndk-r17b编译及使用ollvm-tti步骤(提供编译后文件) ************伸手党直接请看第四步************* ndk-r17b编译及使用ollvm-tti步骤(提供编译后文件) 源码地址: https://github.com/yazhiwang/ollvm-tll 一、编译ollvm-tti 1.git clone https://github.com/yazhiwang/ollvm-tll.git 2.mkdir build 3.cd build 4.修改ollvm-tll\lib\Transforms\Obfuscation\CMakeLists.txt，在最后一行添加 add_definitions(-D_WINDOWS) 让其支持WINDOWS，不修改的话会一直出现"Cannot open /dev/random" 5.cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_LIBDIR_SUFFIX=64 -G "MinGW Makefiles" -DLLVM_INCLUDE_TESTS=OFF ..\ollvm-tll 6.make -j3 二、链接NDK 7.备份NDK_PATH/toolchains/llvm目录 8.删除NDK_PATH/toolchains/llvm/prebuilt/windows-x86_64/目录下所有文件 9.复制build文件夹中的bin、和lib以及lib64 到NDK_PATH/toolchains/llvm/prebuilt/windows-x86_64/目录下三、使用 10.在Android.mk中加入以下就能使用混淆功能了 LOCAL_CFLAGS := -mllvm -sub -mllvm -bcf -mllvm -fla -mllvm -sobf 四、编译后文件下载地址(文件太大上传不了，上传至网盘了) 1.备份NDK_PATH/toolchains/llvm目录 2.删除NDK_PATH/toolchains/llvm/prebuilt/windows-x86_64/目录下所有文件 3.直接解压到NDK_PATH/toolchains/目录就行立即下载

we have some source changes to LLVM/Clang need add into NDK. After download and change "external/llvm" and build NDK from source. It find out that the changes never works. The code in "external/llvm" is dead code and the binary clang/clang.exe is already in NDK source code dir after repo sync which path is below. Does somebody knows how to build Clang toolchains for Android NDK from LLVM/Clang source code? Most Thanks!

The binary clang/clang.exe is already in NDK source code dir below:

https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86
https://android.googlesource.com/platform/prebuilts/clang/host/windows-x86

The binary clang/clang.exe is just copy from NDK source code dir. Not build from source code.

Thanks for answer again. I checked it, but find out it's saying how to build gcc toolchains from source use the build-gcc.sh. I'm sorry to say there is nothing about llvm toolchains which it's already prebuilt binaries placed in below:

https://android.googlesource.com/platform/prebuilts/clang/host/windows-x86/+/refs/heads/master/clang-3362437/bin/

https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86/+/refs/heads/master/clang-3362437/bin/
And there is nothing I can find about how to build it with Google searching or in it's WIKI.

Thanks.

It looks like I need to delete some old docs. The doc you're looking for is https://android.googlesource.com/platform/ndk/+/master/docs/Toolchains.md

Thank you very much! With this link and some test (most times one change need a total rebuild) I finally make it works!
The work also need this:
https://android.googlesource.com/platform/external/clang/+/dev/ToolchainPrebuilts.md

Thanks Again!
