I'm using code here, https://github.com/foomur/programming-ground-up, I'm on a 64 bit pc,
i've installed 32 bit libs
sudo apt-get install gcc-multilib
what I use to assemble and link:
as asm.asm -o asm.o && ld asm.o -o asm
no errors from either assembler, linker, and exe ./asm, but when I use
echo $? I get a return of 0 every time, which I think is an error.
I've tried other assembly code(code isn't the problem), and other assembler and link codes:
as --32 asm.asm -o asm.o && ld -melf_i386 asm.o -o asm
but I think thats an exe for a 32 bit processor(that also shows no errors but an echo of 0 everytime), I don't know what I'm doing wrong. I'm also running Ubuntu through a VM if that matters
