[SOLVED] built nasm from source on android but issue with ld linking

amboxer21 · 08-12-2012, 03:41 AM

Not sure where to put this due to the nature of the content. It is relative to programming, android, and Linux. Anywho, I also posted on xda-developers as well.

I recently installed botbrew on my rooted android device. I built nasm from source and I configured with --host=arm and it built. Then manually installed it in /system/xbin.

I compiled with nasm -felf progname.asm then try and link with ld hello.o -o hello but receive an error.

Code:

 # ld hello.o -o hello
ld: /mnt/sdcard/hello.o: Relocations in generic ELF (EM: 3)
/mnt/sdcard/hello.o: could not read symbols: File in wrong format

What gives? Did I configure nasm wrong?

What's the output of:

Code:

file hello.o

# file hello.o
hello.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped

SIDE NOTE:
I'm running a live Ubuntu session ATM. The reason for the sysv.

Yep .. it's not arm, I did a bit of searching - I don't think arm is supported at all by nasm.

I have just found that out right now. I did a Google search on nasm on arm and the first link I clicked said exactly that. That arm is not supported by nasm.

You can see that by running

nasm -hf

It will show only that x86 is supported. 32 and 64 bit. Windows and Linux.

Its ashame because I love nasms syntax! Arm has their own assembly language.

EDIT:
Output for nasm -HF
