Hello i am trying to follow basic instructions to get Java examples working. Running code

java -Djna.nosys=true -cp "jna-4.2.2.jar:src" examples.SendData

or/and

java -Djna.nosys=true -cp "jna-4.2.2.jar:src" examples.ReceiveData

I got below error;

Creating a new StreamInfo... Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'liblsl64.dylib': Native library (darwin/liblsl64.dylib) not found in resource path (jna-4.2.2.jar:src) at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:277) at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:403) at com.sun.jna.Library$Handler.(Library.java:147) at com.sun.jna.Native.loadLibrary(Native.java:502) at com.sun.jna.Native.loadLibrary(Native.java:481) at edu.ucsd.sccn.LSL.(LSL.java:1101) at edu.ucsd.sccn.LSL$StreamInfo.(LSL.java:160) at examples.SendData.main(SendData.java:8)

@Abdulghany

After our conversation on Slack, I noticed that, in the liblsl_1.12-MacOS.zip file I pointed you to, the liblsl64.dylib file is just a symlink to liblsl64.1.4.0.dylib. They both need to be next to each other in the same folder for liblsl64.dylib to work.

This should solve your Matlab problem. As for Java, I don't know where the libraries are supposed to go so that the java loader can find them. It looks like it should go in a folder named darwin that is "in resource path" but I don't know where the resource path is.

For the sample, it is easiest to put the library in LSL/liblsl-Java. It just has to be somewhere on the path, and in the current directory always works.

@cboulay putting the two files together in java got it working, Thank you. However the matlab problem still persist
