compilar

Hay trampas aquí. Tenga cuidado de no usar la última versión de mingw 8.0.1 para compilar, y se informará un error.
El contenido del error es el siguiente:

PS D:\OLLVM\obfuscator-llvm-9.0.1\build> cmake -G "MinGW Makefiles"  -DCMAKE_BUILD_TYPE=Release ..\..\obfuscator-llvm-9.0.1\
CMake Deprecation Warning at CMakeLists.txt:3 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.


CMake Error at CMakeLists.txt:49 (project):
  The CMAKE_C_COMPILER:

    C:/MinGW/bin/gcc.exe

  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.


CMake Error at CMakeLists.txt:49 (project):
  The CMAKE_CXX_COMPILER:

    C:/MinGW/bin/c++.exe

  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment
  variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
  to the compiler, or to the compiler name if it is in the PATH.


CMake Error at CMakeLists.txt:49 (project):
  The CMAKE_ASM_COMPILER:

    C:/MinGW/bin/gcc.exe

  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment
  variable "ASM" or the CMake cache entry CMAKE_ASM_COMPILER to the full path
  to the compiler, or to the compiler name if it is in the PATH.


-- Configuring incomplete, errors occurred!

Se supone que la posible razón se debe a la compatibilidad de la versión cmake y la versión mingw con cmakelists.txt de ollvm-9.0.1

Luego volví a descargar la versión anterior de mingw. Usé la
dirección de descarga x86_64-5.4.0-release-posix-seh-rt_v5-rev0 mingw.

Comando de compilación
Descomprima el archivo descargado e ingrese al directorio de archivos descomprimidos

mkdir build
cd build
cmake -G "MinGW Makefiles" -DCMAKE_BUILD_TYPE=Release -DLLVM_INCLUDE_TESTS=OFF ../../obfuscator-llvm-9.0.1
cmake --build .

Configurar el NDK de Android

Descargar NDK 21.4.7075529

inserte la descripción de la imagen aquí

Copie el contenido compilado en el directorio especificado del NDK21 descargado

  1. Copie un ndk descargado llamado 21.4.7075529Ollvm9.0.1
  2. Copie clang.exe clang++.exe clang-format.exe de obfuscator-llvm-9.0.1\build\bin en el directorio ollvm compilado en el directorio 21.4.7075529Ollvm9.0.1\toolchains\llvm\prebuilt\windows-x86_64/bin 3. Copie /build/lib/clang/9 Copie los cuatro archivos stdarg.h, stddef .h, __stddef_max_align_t.h y float.h en .0.1/include en el directorio NDK /toolchains/llvm/prebuilt/darwin-x86_64/sysroot/usr/include carpeta utilizada
    por
    AndroidStudio

Modifíquelo en CMakeLists.txt de la siguiente manera

 #设置llvm debug模式混淆编译
    SET(CMAKE_C_FLAGS_DEBUG "${CMAKE_C_FLAGS_DEBUG} -mllvm -fla -mllvm -sobf")
    SET(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -mllvm -fla -mllvm -sobf")
    
    #设置llvm release模式混淆编译
    SET(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -mllvm -fla -mllvm -sub -mllvm -bcf -mllvm -sobf")
    SET(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -mllvm -fla -mllvm -sub -mllvm -bcf -mllvm -sobf")

ofuscación de una sola función

__attribute((__annotate__("bcf")))
__attribute((__annotate__("fla")))
__attribute((__annotate__("sub")))
__attribute((__annotate__("split")))
__attribute((__annotate__("sobf")))
void func(){
    
    
	xxx
}

profunda confusión

SET(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -mllvm -bcf -mllvm -bcf_loop=4 -mllvm -bcf_prob=100 -mllvm -sub -mllvm -sub_loop=2 -mllvm -fla -mllvm -sobf -mllvm -split")

Después de la prueba, descubrí que siempre que se use el archivo de encabezado del estándar c ++, es similar al siguiente

#include <string> 
#include <iostream>

El error anterior aparecerá en el programa.
No sé por qué, pero puedo usar estos archivos de encabezado normalmente cuando pruebo en otra computadora. No sé por qué.
