ollvm-9.0.1's Introduction

O-LLVM 9.0.1

适配 NDK-21.3.6528147(ndk-r21d)

编译命令

cd OLLVM-9.0.1
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_CREATE_XCODE_TOOLCHAIN=ON ../
make -j8 #8是你的CPU线程数量 比如8核16线程可以写 -j16

整合到NDK

打开路径 OLLVM-9.0.1/build/bin/ 找到 clang-9 clang clang-format clang++ 四个文件
复制替换文件到ndk里面去 /Users/用户名/Library/Android/sdk/ndk/21.3.6528147/toolchains/llvm/prebuilt/darwin-x86_64/bin/
最后一步复制对应的头文件到NDK目录下(不然Android项目编译会报错找不到stdarg等头文件错误)，进入刚刚编译的build目录OLLVM-9.0.1/build/lib/clang/9.0.1/include/，然后复制如下文件stdarg.h、stddef.h、__stddef_max_align_t.h、float.h、stdbool.h到 /Users/用户名/Library/Android/sdk/ndk/21.3.6528147/toolchains/llvm/prebuilt/darwin-x86_64/sysroot/usr/include 文件夹下就彻底大功告成了。
注意上面的路径是macOS系统的系统不一样安装路径和darwin-x86_64的名字也会不同

注意事项

项目在macOS 10.15.7 xcode 12.3 的环境上测试成功 Linux系统未测试理论通用 Windows系统有问题需要修改代码才能用(手上没有Windows系统所以未实践)
Windows需要修改的代码随机数问题、头文件问题
aarch64(包括MacBook M1芯片) 上需要修改的问题修改头文件
fla 如果遇到奇怪问题可以看看这个代码修改内容

Android Cmake 食用方式

android {
    ndkVersion = "21.3.6528147"
    defaultConfig {
        externalNativeBuild {
            cmake {
                cppFlags "-std=c++14", "-frtti", "-fexceptions", "-DANDROID_TOOLCHAIN=clang", "-ffunction-sections", "-fdata-sections",
                        "-mllvm", "-sub", "-mllvm", "-sub_loop=3",
                        "-mllvm", "-fla",
                        "-mllvm", "-split", "-mllvm", "-split_num=3",
                        "-mllvm", "-bcf", "-mllvm", "-bcf_loop=3", "-mllvm", "-bcf_prob=40",
                        "-mllvm", "-sobf", "-mllvm", "-aesSeed=0xada46ab5da824b96a18409c49dc91dc3"

                arguments "-DANDROID_TOOLCHAIN=clang",
                        "-DANDROID_STL=c++_shared",
                        "-DANDROID_CPP_FEATURES=rtti exceptions"
            }
            ndk {
                abiFilters 'armeabi-v7a', 'arm64-v8a', "x86", "x86_64"
            }
        }
    }
}

ndk-build 的用法就不用我特意说明了吧毕竟那群混吃等死懒得研究新事物的搬砖工写的文章都是基于这玩意的(也可能是屎山迁移不了cmake)。 (手动狗头
sub_loop、split_num、bcf_loop这些是弄几遍 bcf_prob是这代码每个基本块有40%的概率进行BCF混淆(0-100) 命令具体是干什么的自己搜索引擎去了解懒得挨个写了
"-std=c++14", "-frtti", "-fexceptions", "-DANDROID_TOOLCHAIN=clang", "-ffunction-sections", "-fdata-sections" 这些和ollvm无太大关系什么意思自己查

补充知识

Android 中的ABI armeabi-v7a、x86 是32位的，arm64-v8a是64位的， x86_64这个是两开花的？ arm开头的是arm架构CPU用的的 x86 x86_64是台式机英特尔、AMD CPU用的(一般都是模拟器) 。远古时代的armeabi已经淘汰了，ndk不再支持。理论上只编译个armeabi-v7a就能通杀arm，再加个x86通杀模拟器吧

补充说明

如需借鉴参考这个项目来写博客写文章请直接使用本项目的GitHub链接，不要克隆后用自己的地址分发，为了避免有人提交修复问题的时候弄得到处都是，所以需要统一在这个项目维护方便大家的使用，谢谢合作。

大佬为何我编译混淆会出这个错误。去掉后能正常编译

ollvm 12

Can you update ollvm to 12? I need to be able to use ollvm on NDK 23 witch support flag c++20

集成到ndk中，编译卡死的问题

环境：
Ubuntu 18.04.6 LTS
cmake : 3.10.2
ndk : 21.1.6352462
ollvm : obfuscator base on llvm-9.0.1 (https://github.com/heroims/obfuscator 2dec365146e909f6ca45df7c23603d489f0816dd)

编译完ollvm，照你的方法替换文件后，使用Android Studio编译我的项目，一直卡在 buildCMakeRelWithDebInfo，几十分钟都过不去。

我在项目中试过单独给函数加混淆和全部混淆都会卡死在 buildCMakeRelWithDebInfo ，不知道原因

# 单独给函数加标签
__attribute__((annotate(("sub"))))

# 全部混淆
externalNativeBuild {
    cmake {
        cppFlags "-std=c++11 -mllvm -sub -mllvm -bcf -mllvm -fla -mllvm -sobf -mllvm -seed=0x11223344556677889900aabbccddeeff"
    }
}

有跟我一样情况的吗？

这是基于9.0.0魔改的么还是原版，想知道混淆强度咋样，混淆以后效率会受很大影响么

如题！！！谢啦

你好，请问curl-android你是如何编译通过的？

我编译的时候遇到和你一样的问题，添加你修改的文件还是编译不同，我现在急需编译libcurl.a静态库文件，麻烦你能指点下吗?
万分谢谢

大佬为啥我使用 c++ 标准的头文件就会出现报错

编译报错：fatal error: 'stdbool.h' file not found

MacBook m1 pro ,ollvm 编译后, ndk项目运行出现The C Compile.请问下大佬m1如何修改?

M1是不是不能用AndroidStudio进行NDK开发

按照你的教程操作完了之后出现错误显示The C compile

大佬，有没有MAC NDK 18.1.5063045 版本的 OLLVM？

我从各个版本上去编译都是失败，估计是GCC版本太高了，而且有些不兼容。主要是编译 7.0 的ollvm 版本。

https://github.com/amimo/goron.git
https://github.com/heroims/obfuscator

想问下是否有7.0的版本，直接下载使用。
感谢各位大佬！

Mac下编译遇到如下错误
