How to pack the python source code with data files into one file by Pyinstaller

In your source code, add the res_path(cpath) function as follows:

:fwi.py
def res_path(cpath):
    try:
        base_path = sys._MEIPASS
    except Exception:
        base_path = os.path.abspath(".")
    return os.path.join(base_path,cpath)

[unpack mode]

res_path("app")   => Show the current path with app program 

ex. /opt/app

[After pack]

res_path("app")   => show the _MEIPASS folder path with app program

ex. /tmp/_MEIPASS/app

PS: You must used res_path function with fulled path in your python code. If you want to pack your python code.

Add your data files into fwi.spec files

:fwi.spec 

+ a.datas = [('smartctl','./source/smartctl','DATA'),('hdparm','./source/hdparm','DATA')]

Pack by pyinstaller:

python pyinstaller.py --onefile fwi.spec
