java.library.path

I'm using maven to define my projects. One of my dependencies requires a native DLL at runtime, and consequently it's needed in tests and for debugging. The native DLL is available at a known location. I want a solution that I can check in once and will work for all developers without manual setup by each dev. I know I can set the java.libary.path manually in "run configurations", which will allow it to find the native DLL, but this requires manual setup for each developer. I know I can also set the java.library.path for a given project dependency, but again this is local to a particular

I'm currently trying to set up OpenCV on my 32-bit laptop, but I keep getting an error message which is confusing me: Exception in thread "main" java.lang.UnsatisfiedLinkError: no opencv_java249 in java.library.path at java.lang.ClassLoader.loadLibrary(Unknown Source) at java.lang.Runtime.loadLibrary0(Unknown Source) at java.lang.System.loadLibrary(Unknown Source) at hello.main(hello.java:8) I've tried switching a few things around, like going into User Libraries and changing the Native Library Location to \x64 instead of \x86, but that hasn't worked. I've also made sure that my Java project

I was working on a project that requires loading of native libraries, and so far, all development was restricted to Linux. In order to run my project, I could simply enable forking and modify java.library.path as follows: javaOptions in run += "-Djava.library.path=some/common/path:lib/native/linux" My question is: How can I do the same in a cross-platform way, so that I can share my build.sbt with a Windows-based developer. There are in particular three things that I couldn't figure out so far: I know that SBT allows to construct platform-independent paths like "dir1" / "dir2" , but I'm not

OpenCV libraries gives unsatisfied link error in capturing a video stream. Where should be the opencv 3.2.0 libraries? What is the correct path for packages of opencv classes? Code where to generate this error: package opencv; import org.opencv.core.*; import org.opencv.imgcodecs.Imgcodecs; import org.opencv.videoio.VideoCapture; public class VideoCap { public static void main (String args[]){ System.loadLibrary(Core.NATIVE_LIBRARY_NAME); // error VideoCapture camera = new VideoCapture(0); if(!camera.isOpened()){ System.out.println("Error"); } else { Mat frame = new Mat(); while(true){ if

I want to try JNotify, the plugin library for watching file system changes, but cannot figure out how to configure it. The web page for JNotify says that "java.library.path should point to the location of the native libraries that comes with jnotify (dlls, so dylibs etc)". I am rather new to Mac OS X and don't really know how to do this. I'm using NetBeans and was hoping there was a simple way of adding it to the path in there. I tried it by simply adding the jar file to the Libraries node in the project, and importing it by "import net.contentobjects.jnotify.*;", but that didn't help. I'm

I have java program Client.class that uses cpp shared library libclient.so via JNI. libclient.so is built as shared and uses cpp shared library libhttp.so. libclient.so and libhttp.so are placed in folder /home/client/lib64 Client.class is placed in /home/client/bin Client can load library with System.load and environment variable LD_LIBRARY_PATH System.loadLibrary and -Djava.library.path The first way works fine. export LD_LIBRARY_PATH = /home/client/lib64 java -classpath ./bin Client The secon way fails. java -classpath ./bin -Djava.library.path=./../lib64 Client java.lang

I am trying to use OpenCV with Hadoop. Below is my code. I am just testing if OpenCV libraries works fine with Hadoop, i.e when I am running OpenCV code in function public int run(String[] args) of Hadoop. I searched on the internet, and found some ways of how to add OpenCV native library ( libopencv_java310.so ) in Hadoop. I tried some ways, but it didn't work. For example this tutorial . It says add JAVA.LIBRARY.PATH to hadoop-config.sh file. But it didn't work. I got this error Exception in thread "main" java.lang.UnsatisfiedLinkError: no opencv_java310 in java.library.path at line System
