dd 0
align 2

extern SDL_Init

section .text
global _start
_start:
  mov rdi, 0x20
  call SDL_Init
  xor eax, eax
  inc al
  syscall

i compile it like this

Code:

nasm -f elf64 main.asm -o main.o
ld -o main main.o -lc -m elf_x86_64_obsd -nopie -L/usr/local/lib -lSDL2 -L/usr/X11R6/lib -R/usr/X11/R6/lib
