Little helper class for testing the loading of native libraries in Java.

It simply uses the java.lang.System.loadLibrary(String) call to load the library.

The following command tries to load the libmkl_rt.so library on Linux, which has to be on the path defined by LD_LIBRARY_PATH:

java -jar loadlib4j-0.0.1.jar libmkl_rt.so

The output on stdout will be something like this:

libmkl_rt.so: false libmkl_rt: false mkl_rt: true 

As you can see, loadlib4j also tries the library name without extension and lib prefix. In the above example, the test succeeds with mkl_rt.

The same example in Java:

import com.github.fracpete.loadlib4j.Main; import java.util.Map; ... // the libraries to test String[] libs = new String[]{"libmkl_rt.so"}; Main test = new Main(); Map<String,Boolean> result = test.testLoading(libs); // do something with the results, eg output them for (String lib: result.keySet()) { System.out.println(lib + " -> " + result.get(lib)); }

In this case, the output will be something like this:

libmkl_rt.so -> false mkl_rt -> false libmkl_rt -> false 

• 0.0.1

Use the following dependency to include the library in your Maven project:

 <dependency> <groupId>com.github.fracpete</groupId> <artifactId>loadlib4j</artifactId> <version>0.0.1</version> </dependency>
