undefined reference to `hw_get_module'

[rockyrays]

Hi, I can't solved this problem, I use android-ndk-r13b.

external-btt/jni/btt_daemon_main.c:136: undefined reference to 'hw_get_module' collect2: error: ld returned 1 exit status

I found hw_get_module in libhardware.so, I got the libhardware.so from the phone, then loaded into it, but this will introduce new problems. Can you help me?
