  <p>I now start the debugging process.
  1. I start up a emulator
  2. I debug the application within eclipse.
  3. I make sure that I'm in the hello-jni directory
  4. I enter ndk-gdb --verbose</p>
  
  <p>I've looked at other posts on the subject and the ndk-gdb output always seems to end with something that looks like the following</p>
  
  <pre><code>warning: shared library handler failed to enable breakpoint
  0xafd0c51c in epoll_wait () from /home/zayac/code/android-ndk-r5/samples/hello-jni2/obj/local/armeabi/libc.so
  </code></pre>
  
  <p>It seems that its ready to go with the "epoll_wait ()..." text.</p>
  
  <p>When I run ndk-gdb --verbose I never see that text.  I just get the waring and the (gdb) prompt.  Here's the output...</p>

  <p>When I enter a gdb command like <strong>list</strong>, I get</p>
  
  <blockquote>
    <p>(gdb) No symbol table is loaded.  Use the "file" command.</p>

  <p>Any help would be great!</p>
