make[1]: *** [CMakeFiles/Makefile2:102: CMakeFiles/tdoku_object.dir/all] Error 2
make: *** [Makefile:91: all] Error 2这是因为immintrin.h 头文件用于包含高级向量指令集扩展（such as SIMD, Single Instruction Multiple Data）相关的指令。具体来说，它支持多种Intel的向量指令集扩展，包括SSE、AVX、AVX2、AVX-512等。该头文件提供了一系列用于向量化编程的内在函数（intrinsics），这些函数允许程序员直接使用 处理器的向量指令，而不需要编写汇编代码。
arm64架构没有sse指令集，自然也没有相应头文件。按照网上的提示，下载了将 Intel SSE 指令转换为 ARM NEON 指令的头文件sse2neon.h，保存到源代码所在目录。
https://github.com/DLTcollab/sse2neon/blob/master/sse2neon.h将上述simd_vectors.h文件中的#include <immintrin.h>替换成#include "./sse2neon.h"
还在CMakeLists.txt中添加了如下一行
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -march=armv8-a+fp+simd+crypto+crc")问题3.编译solver_dpll_triad_scc.cc出错
同样需要在solver_dpll_triad_scc.cc文件中添加一行#include <cstdint>，然后就可以编译通过了。
