I am new to lp solve. I am trying to run the following code and getting 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:

Are you sure you load correct libraries in other classes with System.loadlibrary?
If yes, I think quick solution can be putting all libraries in a folder that exists in os's PATH (for instance system32, windows) This has worked for me everytime if there is no any other issue
