Errors cross-compiling from M1 Mac for x86_64 FreeBSD: fatal error: 'inttypes.h' file not found

[n8henrie]

Zig Version

0.10.0

Steps to Reproduce and Observed Behavior

I'm trying to compile a simple test program for x86_64 FreeBSD from Apple Silicon / aarch64-darwin (MacOS 13.1 / Ventura).

$ tar -xf zig-macos-aarch64-0.10.0.tar.xz
$ zig-macos-aarch64-0.10.0/zig version
0.10.0
$ cat <<'EOF' > main.cpp
#include <iostream>

int main() {
    std::cout << "hello, from c++!" << std::endl;
    return 0;
}
EOF
$ zig-macos-aarch64-0.10.0/zig cc -lc++ -o hello_world_cpp main.cpp
$ ./hello_world_cpp
hello, from c++!
$ zig-macos-aarch64-0.10.0/zig cc -lc++ -o hello_world_cpp -target x86_64-freebsd main.cpp

I see the same behavior on homebrew-provided zig as the official downloaded binary I used above. I see the same behavior with env -i HOME=~ zig... (to make sure it's hopefully not something LLVM related in my environment).

Searching through issues, it seems similar / related to:

• homebrew-provided LLVM/Clang prevents zig from building C files #8860
• Proposal: standard wrappers for zig cc and zig c++ #8716

Expected Behavior

I had hoped cross-compilation from aarch64-darwin to x86_64-freebsd would work.
