Troubleshooting Unable to Import DLL Module in Python
Problem Statement:
In an attempt to import a modified version of libuvc on Windows using Python 3.8, the following error is encountered:
Could not find module 'C:\Program Files (x86)\libuvc\lib\libuvc.dll'. Try using the full path with constructor syntax. Error: could not find libuvc!
Analysis:
The error message suggests that Python is unable to locate the libuvc.dll file despite it being found by util.find_library. This indicates a discrepancy in the search method used by ctypes.DLL.LoadLibrary.
Solution:
By bypassing the default search mode, the issue can be resolved by specifying the winmode=0 parameter in the LoadLibrary constructor. This forces the search mode to include the full path to the DLL, allowing Python to locate and load it successfully.
