libraries under /opt are not detected

[bciceron]

under /opt we put libraries our lambda would require to run .
in the lambda envrionment , we'd had to overwrite the default LD_LIBRARY_PATH to search under the newly library path first : $LAMBDA_TASK_ROOT/lib:$LAMBDA_TASK_ROOT/lib64:$LAMBDA_RUNTIME_DIR:$LAMBDA_RUNTIME_DIR/lib:$LAMBDA_TASK_ROOT:/opt/lib:/lib64:/usr/lib64

when the lambda ran it failed with:

/var/task/main: /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by /opt/lib/libheif.so.1)

but both were included in our newley created layer with img2lambda:

$ unzip -l lambda-img/layer-1.zip

so is adding libraries under /opt supported ?

Hi @bciceron ,

If you are storing libraries under /opt/lib and /opt/lib64, shouldn't
$LAMBDA_TASK_ROOT/lib:$LAMBDA_TASK_ROOT/lib64:$LAMBDA_RUNTIME_DIR:$LAMBDA_RUNTIME_DIR/lib:$LAMBDA_TASK_ROOT:/opt/lib:/lib64:/usr/lib64
be $LAMBDA_TASK_ROOT/lib:$LAMBDA_TASK_ROOT/lib64:$LAMBDA_RUNTIME_DIR:$LAMBDA_RUNTIME_DIR/lib:$LAMBDA_TASK_ROOT:/opt/lib:/opt/lib64:/lib64:/usr/lib64

Regards,
Ajitem

@bciceron same issue to me also I just build https://github.com/jeylabs/aws-lambda-poppler-layer but poppler libs are in /opt/lib64 I cound not execute it without setting LD_LIBRARY_PATH could your please explain how did you fix it?
