Adding a file with content like the following and passing --libc <this file> to zig works, RUNPATH is correct and no need to set CC then. --8<---------------cut here---------------start------------->8--- include_dir=/gnu/store/dfx90sc16nphh6bd07sjyri6x4s51zni-glibc-cross-aarch64-linux-gnu-2.39/include sys_include_dir=/gnu/store/dfx90sc16nphh6bd07sjyri6x4s51zni-glibc-cross-aarch64-linux-gnu-2.39/include crt_dir=/gnu/store/dfx90sc16nphh6bd07sjyri6x4s51zni-glibc-cross-aarch64-linux-gnu-2.39/lib msvc_lib_dir= kernel32_lib_dir= gcc_dir= --8<---------------cut here---------------end--------------->8--- For cross builds interpreter path like /lib/ld-linux-aarch64.so.1 is used in output binary, I'll find a way to fix it. > Also for reproducibility, bin/zig is the only file differs and here's the > diff, > I don't know about this part so I currently have no idea on fixing it. This seem to be an upstream issue, Zig is reproducible only on the same machine. I'll verify it and report to upstream.
