Hello,

I use System.loadLibrary to load a shared DLL. This DLL requires other 
depended DLLs. If all (under OSX DYLD_LIBRARY_PATH) is configurated the
System.loadLibrary loads my DLL and everything works fine. I have 
tested the same code with the DYLD-Option is not set, so my Java code 
should be break.
I would like to set the Path to the library like this code:
 String[] l_libraries = { "boost_system", "mylib" };

        try {
            for( String i : l_libraries )
                System.loadLibrary(i);
        } catch (UnsatisfiedLinkError e_link1) {

                File l_temp = new File( 
System.getProperty("java.io.tmpdir") + "mytemp" );
                if (!l_temp.isDirectory())
                    l_temp.mkdirs();


                for( String i : l_libraries ) {
                    String l_lib = l_temp + 
System.getProperty("file.separator") + System.mapLibraryName(i);
                    if 
(System.getProperty("os.name").toLowerCase().indexOf("mac") >= 0)
                        l_lib = l_lib.substring(0, 
l_lib.indexOf(".jnilib")) + ".dylib";

                    System.load(l_lib);
                }
}

My target is: try to load the library and the depended from the default 
system pathes, if not exists than load the libs from
a temporary path. mylib needs a depend boost library, so I load the 
boost lib first, but I get the error:

Library not loaded: libboost_system.dylib   Referenced from: 
/mytemp/mylib.dylib   Reason: image not found

Does anybody know a tip to load all libraries first, so the Java VM can 
work with them from a "fixed" path?

Thanks

Phil
