The error message is as follows: In file included from test/c/main.c:1: In file included from external/zig_sdk/lib/libcxx/include/stdio.h:107: In file included from external/zig_sdk/lib/libc/include/generic-glibc/stdio.h:38: external/zig_sdk/lib/libc/include/generic-glibc/bits/types.h:139:3: error: # error ^ external/zig_sdk/lib/libc/include/generic-glibc/bits/types.h:145:1: error: unknown type name '__STD_TYPE' __STD_TYPE __DEV_T_TYPE __dev_t; /* Type of device numbers. */ Dissected `generic-glibc/bits/types.h:#error`: #if __WORDSIZE == 32 <...> # define __STD_TYPE __extension__ typedef #elif __WORDSIZE == 64 <...> # define __STD_TYPE typedef #else # error #endif So we do not have the `__WORDSIZE`. Where does that come from? Probably from a directory that has an `x86_64` in it. How does that get included? Let's start with `lib/libcxx/include/stdio.h`: 16 #include_next <stdio.h> Now previously our `c++` command line looked like this: external/zig_sdk/tools/c++ \ <...> -Iexternal/zig_sdk/lib/include \ -Iexternal/zig_sdk/lib/libcxx/include \ -Iexternal/zig_sdk/lib/libcxxabi/include \ -Iexternal/zig_sdk/lib/libunwind/include \ -Iexternal/zig_sdk/lib/libc/include/generic-glibc \ -Iexternal/zig_sdk/lib/libc/include/any-linux-any \ -Iexternal/zig_sdk/lib/libc/include/x86_64-linux-gnu \ -Iexternal/zig_sdk/lib/libc/include/x86_64-linux-any \ -Iexternal/zig_sdk/lib/libc/include/x86-linux-any \ -Iexternal/zig_sdk/glibc-hacks \ <...> So the next place it will find `stdio.h` is in `generic-glibc`, which already uses the `__WORDSIZE`. If we make the "next" include to be the arch-specific one instead of the generic-glibc, things start compiling again. Fix the same fo musl.
