zig clang failing to locate stdlib headers

[danielchasehooper]

Zig Version

0.11.0-dev.3395+1e7dcaa3a

Steps to Reproduce and Observed Behavior

Happens on macOS, didn't try other OS.

put this in main.c

#include<assert.h>

int main(int argc, char **argv) {
    assert(argc > 0);
    return 0;
}

These succeed

$ clang main.c
$ zig cc main.c

But this fails

$ zig clang main.c
main.c:2:9: fatal error: 'assert.h' file not found
#include<assert.h>
        ^~~~~~~~~~
1 error generated.

Expected Behavior

zig clang should work

What version of macOS are we talking and what architecture? Also, how did you build Zig?

[kubkon]

As in your other issue, might be fixed by #16212

[kubkon]

Oh, I noticed only now, you're using zig clang. I am not even sure what that should be.

Just checked, this is not fixed by #16212.
