Is there a trick to cross-compile i386 in zig cc?

Help
1

Hello! I’m trying to cross-compile from 64-bit windows 10 to 32-bit, and neither gnu nor msvc options will give me an exe file.

Is this unsupported or am I missing something obvious? Maybe my test file is too complicated :slight_smile:

C:\Users\user\Documents\c test>type main.c
#include <stdio.h>

int main(int argc, char** argv)
{
        printf("Hello, World!\n");
        return 0;
}
C:\Users\user\Documents\c test>zig cc main.c -o mainx64.exe

C:\Users\user\Documents\c test>mainx64.exe
Hello, World!
