Make: Circular ... dependency dropped

When compiling my Android JNI project, I got this error:

make: Circula开发者_JAVA技巧r /obj/local/armeabi/libstlport_static.a <- /obj/local/armeabi/libstlport_static.a dependency dropped.

My question is about the "dependency dropped", what's it's mean?

libstlport_static.a depends upon itself. To avoid infinite loop make just ignores it.
