I’m trying to get the FDB client (for Java) to work on AWS Lambda using their new Layers option. Right now I am putting fdb.cluster in the root and libfdb_c.so in the lib directory. I think it is now finding the library but it is having trouble initializing the FDB class. Has anyone gotten this to work? What else might I need?
Update. Looking more closely it is first failing to load the library. Not sure why it isn’t finding it.

I’m constructing the layer as:
$ zip -u fdb_layer.zip fdb.cluster lib/libfdb_c.so
zip warning: fdb_layer.zip not found or empty
adding: fdb.cluster (stored 0%)
adding: lib/libfdb_c.so (deflated 62%)
