Error: compile libpcap on android with ndk

[wxbhcs]

When I compile the libpcap code with ndk, I came up with errors.

/home/wxb/netFlux/bin/ndk/local/armeabi/libpcap.a(gencode.o): In function `pcap_compile':
/home/wxb/netFlux/jni/gencode.c:389: undefined reference to `pcap_parse'
/home/wxb/netFlux/bin/ndk/local/armeabi/libpcap.a(nametoaddr.o): In function `pcap_ether_hostton':
/home/wxb/netFlux/jni/nametoaddr.c:477: undefined reference to `ether_hostton'
/home/wxb/netFlux/bin/ndk/local/armeabi/libpcap.a(scanner.o): In function `yylex':
/home/wxb/netFlux/jni/scanner.l:336: undefined reference to `pcap_lval'
/home/wxb/netFlux/bin/ndk/local/armeabi/libpcap.a(scanner.o): In function `yy_get_next_buffer':
/home/wxb/netFlux/jni/<stdout>:3739: undefined reference to `pcap_lval'
collect2: ld returned 1 exit status

The libpcap code is from http://android.git.kernel.org/.

Should I compile the whole Android source code?
where is the missing function `pcap_parse', `ether_hostton',`pcap_lval' ?
Is there some source I need to add to the compile?
