Notes

mov eax, 1
mov ebx, 1
int 80h

calling linux system call:
eax -> 1 = sys_exit
ebx -> 1 = exit status

in windows it is equivalent to

extern ExitProcess

call ExitProcess

compile it using:

nasm -f win64 $*.asm -o $*.obj
gcc -nostdlib $*.obj -lkernel32 -o $*.exe

Linux:

• Compile

nasm -f elf -o bin/$*.o src/$*.asm
ld -m elf_i386 -o bin/$* bin/$*.o

• Standard C Functions

nasm -f elf -o $*.o $*.asm
gcc -no-pie -m32 $*.o -o $*

• calling C Functions

nasm -f elf -o $*.o $*.asm
gcc -no-pie -m32 $*.o {c_filename}.c -o $*
