Assistance Needed: Using ZBar with AWS Lambda (Python 3.12)

[aditya-wns]

Hi Team,

I hope you're doing well.

I’m currently working on a serverless solution using AWS Lambda with Python 3.12 to extract barcodes from JPEG images. As part of this, I’m attempting to use the zbarimg CLI tool within a Lambda layer.

Use Case:
The goal is to pass JPEG images to zbarimg and retrieve the barcode data via a Lambda function.

Setup Details:
Environment: Amazon Linux 2 (Cloud9 used for building)

Tool: zbarimg built from source

Lambda Layer Structure:
/opt/
├── bin/zbarimg
├── lib/
├── libzbar.so
├── libjpeg.so
Commands used to build:

git clone https://github.com/mchehab/zbar.git
autoreconf -vfi
./configure --prefix=/tmp/zbar-install --without-qt --without-gtk --without-python --without-x
make && make install
I’ve ensured that libjpeg.so is included in the layer under /opt/lib.

Issue:
When invoking the Lambda function with:

subprocess.run(["/opt/bin/zbarimg", "--raw", "/tmp/test_j.jpeg"])
I receive the following error:

error while loading shared libraries: libMagickWand-6.Q16.so.6: cannot open shared object file: No such file or directory

Thank you for your time and support. I appreciate any insights or recommendations you can provide.

Best regards,
Aditya Takawale
