Usando android-NDK-R7b/samples/Jni-hola como punto de depuración de partida, he construido el jni conandroide NDK-BGF no puede cargar símbolos

Ahora comienzo el proceso de depuración. 1. Arranco un emulador 2. Depuro la aplicación dentro de Eclipse. 3. Me aseguro de que estoy en el directorio hello-JNI 4. entro NDK-BGF --verbose
He mirado en otros mensajes sobre el tema y la salida NDK-BGF siempre parece terminar con algo que se parece a la siguiente
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
parece que ya está listo para ir con el texto "epoll_wait() ...".
Cuando ejecuto ndk-gdb --verbose Nunca veo ese texto. Acabo de recibir el aviso de waring y (gdb). Aquí está la salida ...
