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] at org.fusesource.hawtjni.runtime.Library.doLoad(Library.java:187) at org.fusesource.hawtjni.runtime.Library.load(Library.java:143) at org.fusesource.leveldbjni.JniDBFactory.(JniDBFactory.java:48) at org.lmdbjava.bench.LevelDb$CommonLevelDb.setup(LevelDb.java:147) at org.lmdbjava.bench.LevelDb$Reader.setup(LevelDb.java:200) at org.lmdbjava.bench.generated.LevelDb_readCrc_jmhTest._jmh_tryInit_f_reader1_G(LevelDb_readCrc_jmhTest.java:425) at org.lmdbjava.bench.generated.LevelDb_readCrc_jmhTest.readCrc_SampleTime(LevelDb_readCrc_jmhTest.java:238) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.openjdk.jmh.runner.BenchmarkHandler$BenchmarkTask.call(BenchmarkHandler.java:430) at org.openjdk.jmh.runner.BenchmarkHandler$BenchmarkTask.call(BenchmarkHandler.java:412) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)

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!
