你是VS2017吗?似乎是不支持cpp17导致的,课程要求使用VS2019。 |

我的是VS2019,这个bug是应该MSVC特有的问题,模板里面套 enable if再套模板用fold expression的话,msvc连parse都出错。 因为同样的代码,我切换到Mingw编译器的时候,ndarray.h便不会报这个错误,正常的运行程序。 |

写一下在MSVC编译器下做这个实验室tips
1.开启OpenMP
2. alignalloc.h中的问题
aligned_alloc并未被MSVC支持,但改用其_aligned_malloc即可;3.ndarray.h中模板元编程出Bug
如果不这样更改,会始终报编译器错误 C2059
