When you want to build a binary with pyinstaller :

if anyone using windows to use pyinstaller, i found the solution for it, which is the command below.

you need to use --add-binary for your "exiv2.dll" and use --add-data for your "exiv2api.pyd".

pyinstaller --add-binary “C:\Python310\Lib\site-packages\pyexiv2\lib\exiv2.dll;.” --add-data “C:\Python310\Lib\site-packages\pyexiv2\lib\py3.10-win\exiv2api.pyd;.” --onefile ccc.py
