Can not make executable

[Machoney]

Hi. This is my first project on Linux. I do not exactly know how "executables" works here and quick research showed to use PyInstaller like on Windows.

I'm using:

• Ubuntu 18.04 LTS with system python 3.6
• Python 3.7.4 on venv (i think this is important regarding my problem)
• Bluepy 1.3.0
• Pyinstaller 1.5

The installation went with some warnings, but no one of them concern Bluetooth or bluepy. When I run my program, have error like his:

Traceback (most recent call last):

I went deep into the code, and it looks like the path to the bluepy-helper is incorrect.

helperExe = os.path.join(script_path, "bluepy-helper") used in:

def get_json_uuid():
    import json
    with open(os.path.join(script_path, 'uuids.json'),"rb") as fp:
...

I don't understand why he's referring to the /tmp/ folder, if it's generated from venv.

Did anyone have such a problem?

[Machoney]

Okey, I have figure it out.

I have build bluepy from source in my venv. Then I set to run bluepy-helper as a normal user. sudo setcap 'cap_net_raw,cap_net_admin+eip' bluepy-helper

After that, I have run pyinstaller one more time and it works.

@Machoney can you describe with details what you done to make it works i have the same problem

@bambachas this issue is caused by the required data file from bluepy is missed when PyInstaller trying collect the dependency. Put the attached hook-bluepy.py(change from .txt to .py) under /site-packages/PyInstaller/hooks and re-run the PyInstaller generation process can fix the problem hook-bluepy.txt

It works for me.
