Android NDK: Trying to port JnetPcap

I found a traffic monitoring application for Android, Shark: http://sourceforge.net/projects/prueba-android/ which is based on JnetPcap and has a file with all the source files and the appropriate Android.mk files. I put the jni directory in the samples file of the Android-NDK and I tried to build it using ndk-build -C. During the compilation occurs some errors. Here is the error log I take:

Can anyone help me please?
