Snap7 on Mac (M1)

[aj-88]

Hello,

I'm trying to install Snap7 on my Mac (M1pro).
I installed python-snap7 via the Binary wheel. This install was completed, but it can't find the snap7 library. On my other (windows) laptop I had to add a dll file to a specific folder. After that it worked, but on my Mac I can't find a solution for the missing library problem. I followed the snap7 install for Mac, but for architecture you can only choose i386 or x86_64. I chose the x86_64. But it didn't solve the problem.

My very simple program to test:
import snap7 plc = snap7.client.Client()

Gives the following error:

Traceback (most recent call last): File "/Users/user1/Desktop/test.py", line 3, in <module> plc = snap7.client.Client() File "/opt/homebrew/Caskroom/miniforge/base/lib/python3.9/site-packages/snap7/client.py", line 66, in __init__ self._library = load_library(lib_location) File "/opt/homebrew/Caskroom/miniforge/base/lib/python3.9/site-packages/snap7/common.py", line 75, in load_library return Snap7Library(lib_location).cdll File "/opt/homebrew/Caskroom/miniforge/base/lib/python3.9/site-packages/snap7/common.py", line 66, in __init__ raise Snap7Exception(msg) snap7.exceptions.Snap7Exception: can't find snap7 library. If installed, try running ldconfig

I hope you guys can help me out.
Thanks in advance!

@aj-88 If you don't want to wait, you can install the package manually from the latest build:

1. download the latest build
2. unzip wheels.zip
3. run python3 -m pip install /path/to/wheels/macOS/python_snap7-1.1-py3-none-macosx_10_9_universal2.whl
