java.lang.UnsatisfiedLinkError: no jniRealSense in java.library.path

[pierre03]

Hello,
I created a project maven and added the dependency:

org.bytedeco.javacpp-presets
librealsense-platform
1.9.6-1.3

then, i added the example TestConnection.java, but i have always the error no jniRealSense in java.library.path
Can you tell me how to solve the error, please?

If you're trying this on Windows, there are no builds available yet. Contributions welcome though! Let me know if you encounter any issues with the build and I'll help.

What is the rest of the stack trace with the cause of the error?

[pierre03]

I found this link, someone have the same error, but i can not understand.
[https://stackoverflow.com/questions/43208145/how-to-use-javacpp-presets-binaries]

[pierre03]

The detailMessage in the cause is "no jniRealSense in java.library.path
but i see that the loadedLibraries's length is 0, the jniRealSense lib maybe the first one to load.

[pierre03]

Is there any parameter i should configure in the pom?

[saudet]

Well, if there are no causes, then that file really isn't in your class path. Check the sample pom.xml file for how to do this.

[saudet]

I've just remembered, there are no binaries for Mac either, yet:
https://github.com/bytedeco/javacpp-presets/blob/master/librealsense/platform/pom.xml
Contributions are welcome though! Let me know if you encounter any problems with the build and I will help.

[pierre03]

So, i have to develop and run my program juste on Linux?

[pierre03]

I downloaded the binaries from maven repository, can you tell me when you could upload the new complete version, please?

[saudet]

No, we can build binaries for Mac and Windows as well, but someone has to take the time to do it.

[pierre03]

Thank you, i'll wait for it.

[saudet]

I've added support for Mac and Windows in the latest commit above. Enjoy!

[saudet]

And they have now been released with version 1.4:

Thank you for your patience!
