Hi,
can someone help me with loading native libraries in an eclipse fragment? My fragment on a Linux 64 bit system contains the following code:
public void loadLibraries()
{
System.out.println( "LD_LIBRARY_PATH: " + System.getenv( "LD_LIBRARY_PATH" ) );
try
{
System.out.println( "Loading library 2" );
System.loadLibrary( "2" );
System.out.println( "Loading library 1" );
System.loadLibrary( "1" );
System.out.println( "Finished loading libraries!" );
}
catch( UnsatisfiedLinkError unsatisfiedLinkError )
{
unsatisfiedLinkError.printStackTrace();
}
}
and two libraries "lib1.so" and "lib2.so" in the fragment root path.
Loading library 2 works great, since it does not depend on any other libraries. But library 1 is linked against library 2. When I try to load it I get this output:
------------------------------------------------------------ -------------------------
LD_LIBRARY_PATH: /usr/lib/jvm/java-6-sun-1.6.0.22/jre/lib/amd64/server:/usr/l ib/jvm/java-6-sun-1.6.0.22/jre/lib/amd64:/usr/lib/jvm/java-6 -sun-1.6.0.22/jre/../lib/amd64:/usr/lib64/xulrunner-addons
Loading library 2
Loading library 1

I have searched the internet for hints how to load libraries with dependencies, but the only advice I have found was to load the base libraries before the depending libraries. In the example above I already do this, but it does not work.
Can someone help me?
Thank you very much,
Benjamin Bihler
