I'm not familiar with how anaconda packages libraries.
@murat-bal what is your OS ?
What is the content of home/muratbal/anaconda3/envs/gst_env/lib/clang ?
I'll push a generic fix

[trolldbois]

@murat-bal would you be able to pip install git+https://github.com/trolldbois/ctypeslib.git to see if the patch I pushed fixes your issue ?
it seems that on your platform, the ctypes.util.find_library returns a library folder path, and not a specific filename.
which is possible as per documentation
https://docs.python.org/3/library/ctypes.html#finding-shared-libraries

[trolldbois]

@murat-bal would you be able to re-try ?

pip install ctypeslib2 clang==14

or whatever version of clang you are using .
