[obj/local/armeabi/objs/AMExtractor/kernel_pfn.o] Error 1

Hi,
I have created a Nexus4 emulator and set

define CONFIG_NEXUS4

define DEVICE "CONFIG_NEXUS4"

in config.h.

When I try to run the first command I got an error:
[mex@shrek AMExtractor-master]$ /home/mex/prj/cyber/mobiFore/android-ndk-r11c/ndk-build NDK_PROJECT_PATH=. APP_BUILD_SCRIPT=Android.mk

Have you an idea how to fix it, please?
Thanks

Add #include <sys/types.h> into kernel_struct.h.

Seems like loff_t is not defined.
There might be mistakes about include path in my code
