Code similarity preprocessing : extract_obj.py: error: ambiguous option: -a could match -asm_t, -asm

[smartappcoder]

I have troubles to run Binary code similarity measures by following the README instructions:

Binary code similarity measures
1. Download dataset                                                                                      
    . Download POJ-104 datasets from here and extract them into data/.

2. Compile and preprocess                                                                         
    Run python extract_obj.py -a data/obj (clang++-3.7.1 required)`

I downloaded the datasets and put it under nberf/data. Since there is no extract_obj.py under nberf, I changed the command to

  (py3_env): python preprocess/extract_obj.py -a data/obj` 

I got

usage: extract_obj.py [-h] [--poj-dir POJ_DIR] [--filter-list FILTER_LIST] [--asm_type {x86,mips}] [--output-asm-dir OUTPUT_ASM_DIR]
                                   [--num-workers NUM_WORKERS]
extract_obj.py: error: ambiguous option: -a could match -asm_t, -asm  

Look at the parse_args in extract_obj.py, there is no '-a' argument, it seems to be a typo of -asm.
If I copy data to preprocessing and run the command:

  (py3_env) nberf: cp -r data preprocess/data
  (py3_env) nberf: cd preprocess
  (py3_env) nberf/preprocess: python extract_obj.py -asm data/obj` 

now I got

Traceback (most recent call last):
  File "extract_obj.py", line 218, in <module>
    main()
  File "extract_obj.py", line 181, in main
    with open(args.filter_list) as f:
FileNotFoundError: [Errno 2] No such file or directory: './preprocess/filter_list.txt'

My env

Ubuntu 20.04.2 LTS
Python 3.8.5

Any steps I misunderstood or missed? Any help is greatly appreciated.

I got the same thing, and typed python extract_obj.py -j ./data/obj -f ./filter_list.txt to get around both of those errors.

Hi Dennis,

Sorry for the typo in README. You should preprocess the code by running:
python preprocess/extract_obj.py -asm data/obj

ok @smartappcoder, README is updated
Thanks @ChengFu0118 , who is the first author of N-Bref.
