我有一个使用JOCL库(http://www.jocl.org/)的项目,并有多个模块.当我从命令行运行"./activator test",或在SBT控制台中运行"test"命令时,我收到如下错误:

[info] Exception encountered when attempting to run a suite with class name: pl.tarsa.sortalgobox.opencl.CpuMergeSortSpec *** ABORTED ***
[info]   java.lang.UnsatisfiedLinkError: Error while loading native library "JOCL_0_1_9-linux-x86_64" with base name "JOCL_0_1_9"

我正在编写一个简单的应用程序,Scala它通过leveldbjni库使用leveldb数据库.我的build.sbt文件看起来像这样:

name := "Whatever"

version := "1.0"

scalaVersion := "2.10.2"

libraryDependencies ++= Seq(
    "org.iq80.leveldb" % "leveldb-api" % "0.6",
    "org.fusesource.leveldbjni" % "leveldbjni-all" % "1.7"
)

Object然后,An 负责创建数据库.不幸的是,如果我运行该程序,我会回到一个java.lang.UnsatisfiedLinkError由引擎盖下利用的hawtjni库引发的leveldbjni.

也可以通过scala控制台轻松触发错误:

scala> import java.io.File
scala> import org.iq80.leveldb._
scala> import org.fusesource.leveldbjni.JniDBFactory._
scala> factory.open(new File("test"), new Options().createIfMissing(true))

java.lang.UnsatisfiedLinkError: org.fusesource.leveldbjni.internal.NativeOptions.init()V

...
scala> System getProperty "java.io.tmpdir"
res2: String = /var/folders/1l/wj6yg_wd15sg_gcql001wchm0000gn/T/

我无法理解正在发生的事情,因为从jar文件中正确地提取了库,但由于某些原因它没有被加载.
