Cannot run movcc compiled files

[hrkrx]

i managed to compile a simple HelloWorld program with movcc.

#include <stdio.h>

int main()
{
    printf("Hello World");
    return 0;
}

when i compile it with gcc it just works, but when using movcc i get the following error:

bash: ./program: cannot execute binary file: Exec format error

i checked the format of both files, which are indeed different:

gcc produces an elf64-x86-64 binary

movcc produces an elf32-i386 binary

i tried to pass "-m elf_x86_64" with -Wl but then i get another error:

/usr/bin/ld: Incompatible /mnt/d/TMP/C/git/movfuscator/build//gcc/32/libgcc.a skipped search of -lgcc

What am i doing wrong?

movcc only compiles to 32 bit elfs. You seem to have a 64 bit host.
In order to run the produced file you need to fix some things. Look here for further information.

This does not fix the issue for me, could it be that MOVfuscator is attempting to link to 64-bit shared libraries? @xoreaxeaxeax should take a look at this.

Ah, I have discovered the cause of my issue. Windows Subsystem for Linux only allows emulation of 64-bit ELFs for the kernel, not 32-bits. Apparently 32-bit support is not planned. After patching the fixes in #31 and moving to a Kali Linux computer, movcc compiles C files properly.
