I want to run zmq with java. I had tried to do it like in a question

I compiled project https://github.com/zeromq/libzmq then https://github.com/zeromq/jzmq

After all run my program with argument -Djava.library.path=C:\zmq\jzmq\jzmq-jni\builds\msvc\x64\Release\;C:\zmq\libzmq\bin\x64\Release\v141\dynamic

import org.zeromq.ZMQ;

public class TestZMQ {

    public static void main(String[] args) throws Exception {
        ZMQ.Context context = ZMQ.context(1);
    }
}

As a result I have exception

Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\zmq\jzmq\jzmq-jni\builds\msvc\x64\Release\jzmq.dll: Can't find dependent libraries
    at java.lang.ClassLoader$NativeLibrary.load(Native Method)
    at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1941)
    at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1857)
    at java.lang.Runtime.loadLibrary0(Runtime.java:870)
    at java.lang.System.loadLibrary(System.java:1122)
    at org.zeromq.ZMQ.<clinit>(ZMQ.java:40)
    at TestZMQ.main(TestZMQ.java:8)

Dependency walker shows multiple errors. People says it appear because of walker own, not library. enter image description here

Thanks for any help.

There is the problem with java.library.path in windows. Normally it takes system var Path and put it into java.library.path. When I set -Djava.library.path=myLybraryPath, it became myLybraryPath, but you need something like this ${java.library.path};myLybraryPathotherwise your application can't find windows libs.

I've found the solution of this problem by adding my library in Path's system variable. There is another similar solution

set PATH=%PATH%;myLybraryPath

PS: There is no the same problem in linux. It's just windows' jvm realization problem.
