How to compile using nasm on MacOSX

Question

I am trying to compile and link my first program on Assembler. I try to compile the following code:

; %include \"stud_io.inc\"    
global _main     

section .te         


        

Answer 1

I would recommend first updating your NASM.

After that, try running this:

nasm -f macho64 main.asm -o main.o  && ld -e _main -macosx_version_min 10.8 -arch x86_64 main.o -lSystem

Notice that the new command adds JasonD's suggestion above (macho64), but also adds the -lSystem to the ld command to stop ld from throwing following error:

ld: dynamic main executables must link with libSystem.dylib for architecture x86_64
