simple hello.asm (NASM) not compile in x64, plz help

[eric lin]

hello:
I copied a simple hello.asm  (NASM) assembly program from 
www.tldp.org/HOWTO/html_single/Assembly-HOWTO/
try to compile and run on my linux 64(ubuntu14.04), but I got errors:

-------------------------------------

ld -s -o heworl heworl.o 
ld:i386 architecture of input file *.o is incompatible with i386:x86-64 output
-------------------------------------------------
please help,(how to make it compile and run on my 64 platform rather than ask me switch to 32 bit platform),thanks a lot ina dvance, eric

You told nasm to create a 32-bit .o file. Tell nasm to create a 64-bit
.o file instead. Use "-f elf64" instead of "-f elf32".

The command "nasm -hf" will display all the valid output formats that
nasm supports.

If you’re interested in using the gnu programming environment, I have written an introductory textbook on the topic. You can get more information at http://bob.cs.sonoma.edu/. I sell it at lulu.com, but you can download a preview copy (first seven chapters) for free from my website. It’s specifically about the 64-bit platform.

I normally use gold (linker) and yasm (like nasm) since they are more
64-bit friendly.
My Makefile is thus:

hello: hello.o
	gold hello.o -o hello
hello.o: hello.asm
	yasm -f elf64 -g dwarf2 -o hello.o hello.asm

You can use the entries individually or just copy and paste into your
own Makefile and type: make
That will make .o file and link it for the executable, but don't forget
to rename "hello" to "heworl" in every instance, so it will have the
name you chose.
Hope this help!
