how to use decuda (newbie question)

I downloaded decuda, so that I could disassembly my kernels.

Now I was trying to disassembly an obj file (maybe I need a ptx file instead) but I always got something like:

Traceback (most recent call last):
File “C:\decuda-0.4.2\”, line 89, in
File “C:\decuda-0.4.2\”, line 52, in main
cu = load(args[0])
File “C:\decuda-0.4.2\”, line 255, in load
inst = [int(x,0) for x in inst]
ValueError: invalid literal for int() with base 0: “d\x86\x14\x00\xc2’\xd6I\xc4

So how do I generate a ptx file or how can I disassembly my obj file?

Well I read here ( that I must use the --ptx option. So I guess this will solve my problem (still haven’t tested it)
