Error in running tests

[s-noghabi]

I am trying to run the benchmark, but I get the following error:

java.lang.UnsatisfiedLinkError: Could not load library. Reasons: [no leveldbjni64-0.0.1-SNAPSHOT in java.library.path, no leveldbjni-0.0.1-SNAPSHOT in java.library.path, no leveldbjni in java.library.path]

Can you help on how I can fix this?

Thanks!

I'm unsure why you are seeing that message.

On a clean machine I just ran mvn clean package then quickly tested LevelDb via java -jar target/benchmarks.jar -f 1 -wi 0 -i 1 LevelDb:

Are you using 64-bit Linux?

I was using a Mac. I moved to Linux and it got fixed. Thanks!
