How can you exit and compile a .am file [duplicate]

Question

I am using terminal on mac. I did 'vim hello_worldd.asm' and it created a place for me to write my code.

But I don't know how to exit and run it. Is there a command to do so?

Quit and save the file (hit the escape key then type :wq) from vim. Then run the assembler (probably nasm hello_worldd.asm) — Kevin

To exit Vim, hit the ESC key to go to normal mode and then type: :wq to exit and save changes.

For NASM, use:

nasm -f elf file.asm to compile it.

Then you must link it so you can use:

ld -s -o outfile file.o

Then run with: ./outfile.

If you can't run ./outfile. You probably have a permission issue. Which you can fix by using chmod doing: chmod +x outfile.

thank you, but when I do ./outfile, I get permission denied

This answer is incorrect. nasm will only compile (assume ELF) to an object . You'll have to link it with LD (or GCC) first.

can you elaborate please?

@MichaelPetch Is that better? Thanks for the catch.
