Java.lang.UnsatisfiedLinkError: cannot find dependent libraries

Question

I am new to lp solution. I am trying to run the following code and get the following error:

package package1; /** * Created by ANJANEY on 6/13/2014. */ import lpsolve.*; public class Demo { public static void main(String[] args) { try { // Create a problem with 4 variables and 0 constraints LpSolve solver = LpSolve.makeLp(0, 4); // add constraints solver.strAddConstraint("3 2 2 1", LpSolve.LE, 4); solver.strAddConstraint("0 4 3 1", LpSolve.GE, 3); // set objective function solver.strSetObjFn("2 3 -2 3"); // solve the problem solver.solve(); // print solution System.out.println("Value of objective function: " + solver.getObjective()); double[] var = solver.getPtrVariables(); for (int i = 0; i < var.length; i++) { System.out.println("Value of var[" + i + "] = " + var[i]); } // delete the problem and free memory solver.deleteLp(); } catch (LpSolveException e) { e.printStackTrace(); } } } 

Error:

 Exception in thread "main" java.lang.UnsatisfiedLinkError:E:\HIVEMINDS\ThirdProject\lp_solve_5.5.2.0_dev_win64\lpsolve55j.dll: Can't find dependent libraries at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary1(ClassLoader.java:1957) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1882) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1872) at java.lang.Runtime.loadLibrary0(Runtime.java:849) at java.lang.System.loadLibrary(System.java:1087) at lpsolve.LpSolve.<clinit>(LpSolve.java:275) at package1.Demo.main(Demo.java:14) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:134) 

Answer 1

Are you sure to load the correct libraries in other classes using System.loadlibrary?

If so, I think a quick solution can put all the libraries in a folder that exists in os PATH (for example, system32, windows). This worked for me every time if there is no other problem.
