How to load a library .so /.dll at startup

Troubleshooting General Help
1

hy yall,



sorry for this basic question that is not link to JME, but i didn’t found any interresting result via google, and i know that this behavior is done by JME, cause we don’t need any LD_LIBRARY_PATH to set before startup.



so what’s the ggod way to do it ?



thanks

to be more accurate on my need, the library will idealy be in a jar file

i’m going to try something based on that :



[java]public static void loadNativeLibrary() throws Exception {

if( LIB_LOADED == false ) {

String libname = System.getProperty(“os.name”)

  • “_”
  • System.getProperty(“os.arch”)
  • “.lib”;

    ClassLoader cl = Class.forName(“sqlite.tools.ASCIIDataFileLoader”)

    .getClassLoader();

    InputStream in = cl.getResourceAsStream(libname);

    if (in == null) {

    throw new Exception("libname: "
  • libname

    +" not found (supposed to be in sqliteimporter.jar)");

    }

    /*
  • Extract the lib file and link it with the app

    */

    File tmplib = File.createTempFile(“libsqlitejdbc-”, “.lib”);

    tmplib.deleteOnExit();

    OutputStream out = new FileOutputStream(tmplib);

    byte[] buf = new byte[1024];

    for (int len; (len = in.read(buf)) != -1;) {

    out.write(buf, 0, len);

    }

    in.close();

    out.close();

    System.load(tmplib.getAbsolutePath());



    LIB_LOADED = Boolean.TRUE;

    }

    }[/java]



    found on a french website : http://astro-saada.blogspot.com/2010/05/mettre-des-librairies-natives-dans-un.html



    Is that a good way ? is that who you guys do for lwjgl ?

I think what you do is just extracting the lib from the jar and copying at the root of the project, to do not have to use System.load…



arff, i really have a bad time with that
