我在Mac上使用mpi时遇到问题 作为大学项目，我用c ++编写了一个简单的mpi代码。我已经用brew安装了llvm。 当我想使用mpicc编译代码时，它显示了一个错误：
>In file included from main.cc:4:
>In file included from >/usr/local/opt/llvm/bin/../include/c++/v1/iostream:38:
>In file included from >/usr/local/opt/llvm/bin/../include/c++/v1/ios:215:
>In file included from >/usr/local/opt/llvm/bin/../include/c++/v1/iosfwd:96:
>/usr/local/opt/llvm/bin/../include/c++/v1/wchar.h:119:15: fatal error:
> 'wchar.h' file not found
> `#include_next <wchar.h>`
>1 error generated
我尝试重新安装我的gcc，xcode甚至llvm。我已经尝试了所有可能的答案，但找不到任何答案。 有帮助吗？
