Question

我正在尝试在使用sbt构建的Scala应用程序中使用opencv，这是我的build.sbt

name := "Marker"

version := "1.0"

scalaVersion := "2.11.8"

javaOptions in run += "-Djava.library.path=/home/priyatham/libs/opencv-3.1.0/build/lib"

这是我在sbt run

时得到的错误

我修改java.library.path

的方式出了什么问题

编辑：我确实将opencv-310.jar放在Marker/lib文件夹

中

使用java -Djava.library.path="/home/priyatham/libs/opencv-3.1.0/build/lib"进行编译可以正常工作，但不适用于sbt run

编辑：

添加fork in run := true。我想现在它试图在同一个JVM中运行你的代码，所以不应用javaOptions。

尝试加载opencv时出现java.lang.UnsatisfiedLinkError
