How can I invoke feature_map.py example?

[baikaishiuc]

I'm a freshman in python and binary ninja

According https://github.com/Vector35/binaryninja-api/tree/dev/python/examples,

I update PYTHONPATH and import most python/examples module , invoke it is ok.

But when I:

import feature_map
Traceback (most recent call last):
  File "/Users/zxw/Library/Application Support/Binary Ninja/plugins/feature_map.py", line 21, in <module>
    bv = binaryninja.open_view(sys.argv[1], update_analysis=True)
IndexError: list index out of range
Python plugin 'feature_map' could not be loaded

it seems i need pass one argument to feature_map, but i dont know how to pass filename when I import it.

From that code alone (I haven't looked at the larger example recently) it looks like it's meant to be run directly like ./feature_map.py , not imported. Note however that would require a commercial license for headless support.

If you are trying to run in the console on non-commercial it would likely require some code changes.

thank you, the error shows my binary ninja is personal license.
