Windows\System32\lpsolve55j.dll: Can't find dependent libraries

java, lpsolve, maven

Solution

I did the following thing and it seems to work:

- Downloaded the dev package that fits my processor (64 bit)

- Extracted the archive into a folder

- Copied lpsolve55j.jar and lpsolve55j.dll into the directory from step 2

- Added the directory from step 2 to the PATH

- Included lpsolve55j.jar from the directory in step 2 into my java project (as an external directory).

Now it works.

Problem

When I try to use LPSolve for Java (mavenized version, http://code.google.com/p/lpsolve-java/source/checkout ), I get following error: ``` java.lang.UnsatisfiedLinkError: C:\Windows\System32\lpsolve55j.dll: Can't find dependent libraries at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(Unknown Source) at java.lang.ClassLoader.loadLibrary(Unknown Source) at java.lang.Runtime.loadLibrary0(Unknown Source) at java.lang.System.loadLibrary(Unknown Source) at lpsolve.LpSolve.<clinit>(LpSolve.java:274) ``` I - put lpsolve55j.dll in Windows\System32 and - added the directory C:\Program Files\LPSolve IDE to the PATH environment variable. The error occurs both in eclipse (test case) as well as during execution of "mvn test". None of this helps. How can I fix this error?
