Failed using the clang2py command on windows - clang not found error

[qaxntl]

Quite new to this, so bare with me!

Trying to wrap a header + dll file to python code on Windows 11 using miniconda.
I made a new conda environment and activated it.
I installed clang via conda install clang (installed version 14.0.6).
Then, I cloned the repo from github.
Then I installed via pip install . clang==14 (Also tried pip install ctypeslib2 clang==14).

Either way I install ctypeslib, I get this error when I run clang2py -o my_lib.py -l my_lib.dll my_lib.h:

C:\Users\[username]\.conda\envs\ctypeslib\Lib\site-packages\ctypeslib\__init__.py:112: RuntimeWarning: Could not find the clang library. please install llvm libclang

I do not understand the error's suggestion in the context of running this command from the command line. Could you please give me any suggestions on how to solve this issue?

I met this too, and i try to run the command in an actual .py file just like said "Try using the full path with constructor syntax.. To provide a path to libclang use Config.set_library_path() or Config.set_library_file()." This time he knows where the dll is but still error as ' RuntimeWarning: Could not find the clang library. please install llvm libclang"

@qaxntl @Playitcooool Can you find the installation path of the libclang.dll file ?
Can you try setting environment variable CLANG_LIBRARY_PATH to that path ?

Also @Playitcooool this is a RuntimeWarning. If you ignore it and use Config.set_library_file(), you should be able to use ctypeslib as a library
