| How to import .so files in AWS Lambda (python)? Posted on: Nov 28, 2019 4:00 AM | | This question is not answered. Answer it to earn points. |
I'm trying to import .so files using ctypes.util.find_library() in Python. The files are built with Amazon Linux docker image.
To import the files I tried creating a layer where they're present in /lib/ . I also tried to directly add /lib/ directory in the zip file containing my code. But the files are not detected. Files present in Lambda's default lib directory are getting detected, eg. find_library('png') gives libpng.so.3 as result.
LD_LIBRARY_PATH environment variable contains /opt/lib but Lambda can't read my files

In Python 3.6, no error. But in Python 3.8, it raises ImportError. I believe AWS Lambda's Python 3.8 is corrupted.

| Re: How to import .so files in AWS Lambda (python)? Posted on: Jan 26, 2020 3:29 PM | The problem with find_library in Python 3.8 Runtime is that it relies on ld command (which does not exist in Amazon Linux 2-based Lambda environment) to search for libraries in LD_LIBRARY_PATH.
The new Amazon Linux 2 environment in Lambda is very bare-bone and has been stripped off a lot of utilities.
To have the ld command available on new lambda environment, following commands will attempt to retrieve/extract the binutils package, then put them into a layer.zip file, from which can be used as Lambda Layer source.

To find out the dependencies, use the ldd tool.
To verify they are installed correctly run:

Before you can !pip install pyzbar, you need to install libzbar with this command.
Then, pyzbar should work.
