NASM on Termux

[vlig]

Hello!

Is it possible in some way to learn NASM on Termux? I do aware I'm on ARM (aarch64), and NASM is for x86 only. But there's nasm package and there're qemu-* packages, so I'm pretty sure there's also some way to manage it using emulation in the right manner. Googling haven't helped much.

What I'm trying to do:
got some Intel x86 ASM helloworld code;
nasm -f elf hello.asm - assembles OK;
ld -m <whatever> -s -o hello hello.o - obviously won't work (in the ASM tutorial I'm using it's said to use -m elf_i386 - no way on ARM), with the following error:

ld: hello.o: relocations in generic ELF (EM: 3)
ld: hello.o: error adding symbols: file in wrong format

The answer is: use ld.lld instead of ld.
So the full chain is:

$ nasm -f elf hello.asm
$ ld.lld -m elf_i386 -s -o hello hello.o
$ qemu-i386 hello
Hello, world!

The ASM source itself:

section .text
   global _start     ;must be declared for linker (ld)
     
_start:             ;tells linker entry point
   mov  edx,len     ;message lenght
   mov  ecx,msg     ;message to write
   mov  ebx,1       ;file descriptor (stdout)
   mov  eax,4       ;system call number (sys_write)
   int  0x80        ;call kernel
     
   mov  eax,1       ;system call number (sys_exit)
   int  0x80        ;call kernel
 
section .data
msg db 'Hello, world!', 0xa  ;our dear string
len equ $ - msg     ;lenght of our dear string
