JavaCV 1.5 + Gradle + IntelliJ

[Roman Schulte]

Hi @all,

i'm currently trying to get JavaCV running inside IntelliJ using Gradle as build system. I've followed the README of the GitHub repository

and added `compile group: 'org.bytedeco', name:'javacv-platform', version:'1.5' ` to my `gradle.build` file.

After running `gradle build` I can see the library and their (native) dependencies inside the module classpath of the project.

But when I run my application and call `Loader.load(Imgcodecs::class)` in the first line of my main method, i get following error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jniImgcodecs in java.library.path: [/Users/roman/Library/Java/Extensions, /Library/Java/Extensions, /Network/Library/Java/Extensions, /System/Library/Java/Extensions, /usr/lib/java, .]

at java.base/java.lang.ClassLoader.loadLibrary(ClassLoader.java:2660)

at java.base/java.lang.Runtime.loadLibrary0(Runtime.java:827)

at java.base/java.lang.System.loadLibrary(System.java:1902)

at org.bytedeco.javacpp.Loader.loadLibrary(Loader.java:1336)

at org.bytedeco.javacpp.Loader.load(Loader.java:1077)

at org.bytedeco.javacpp.Loader.load(Loader.java:963)

at MainKt.main(Main.kt:11)

As far as I understand, this means the native library of OpenCV is missing in the classpath, but I'm not sure what I need to do in order to get JavaCV running?

I'm running macOS and can see the `org.bytedeco:opencv:macosx-x86_64:4.0.1-1.5` in the IDE's libraries view.

Did anyone of you face a similiar situation and knows a possible solution?

Greetings,

Roman

Hi Khin,

thanks for your response. Sadly this doesn't work for me.

How did you integrate JavaCV into your project? Via Gradle or manually?

Greetings,
Roman

We actually need to call `Loader.load(opencv_java.class)` as explained
