MacOS: fatal error: 'memory.h' file not found

[stkevintan]

I replace clang++-8 with clang++ in README.md ,since my clang version is already 8.0.0; but when runing make in terminal, I encounter an error:

[PetterS]

I forgot what that was used for. What fails if it is removed?

Perhaps it should be <string.h> instead? Can you try this?

[stkevintan]

@PetterS <string.h> still doesn't work. I guess, did you forget some compile flag , like --sysroot?

[PetterS]

Well, what is the error if you remove the header?

[stkevintan]

same error except 'memory.h' becames to 'string.h'

[PetterS]

OK, I meant without the headers at all.

But <string.h> is a standard C header. So I'm afraid I can't help you here. Clang should need that to do just about anything.

I figure out the cannot found errors by tweak my mac commandline tools. but, I encounter some other errors:

Do you test it in Mac OS X system ? I'm not sure if it is related to OSX

[PetterS]

No, I don't have a Mac, nor do I have access to one.

[PetterS]

But the error message "#error Unsupported architecture" seems to suggest that it is impossible with your current architechture?
