I'm having issues compiling a C program and running it on a Windows 7 64bit machine.

Here's my script:

#include <stdbool.h>
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{
     bool isCaseSensitive = false;
     enum { CHARACTER_MODE, WORD_MODE, LINE_MODE } mode = CHARACTER_MODE;
     size_t optind;
     for (optind = 1; optind < argc && argv[optind][0] == '-'; optind++)
     {
         switch(argv[optind][1])
         {
             case 'h': isCaseSensitive = true; printf("Help page"); break;

         default:
             fprintf(stderr, "Usage: %s [-h]\n", argv[0]);
             exit(1);
        }
    }
}

Firstly I'm compiling this script using Ubuntu 16.04 over vmware with a Windows 7 host. When I run: gcc -m64 utilis.c -o utilis.exe it will compile, but if I run it on my host I get this error:

If I try to compile it using 32bit, and having one of my buddies run it on his 32bit machine I get the following: 

/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.9/libgcc.a when searching for -lgcc
/usr/bin/ld: cannot find -lgcc
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.9/libgcc_s.so when searching for -lgcc_s
/usr/bin/ld: cannot find -lgcc_s
collect2: error: ld returned 1 exit status

If I have him run the 64bit one he gets this error:

What I've tried to do about this:

How can I get my program to compile correctly and be cross compatible to my Windows 7 machine?

Figured it out, you need to install mingw toolchain for linux.

sudo apt-get install x86_64-w64-mingw32-g++
e@ubuntu:/mnt/hgfs/devshare/utilis$ mg++ utilis.c -o utilis.exe --static
C:\Users\z-perkins-thomas\Documents\bin\testenv\devshare\utilis>utilis.exe -h

Here's a step by step on cross compiling C programs to run them on Windows
