Help with linking v8 libraries with android code

[Dzung Tran]

I built the v8 libraries using GN using these args:

    is_debug = false

    v8_static_library = true

    v8_target_cpu = "arm"

    target_os = "android"

    target_cpu = "arm"

I got these libraries:

 

parallels@ubuntu:~/v8$ find out.gn/ -name *.a

out.gn/arm.release/clang_x86_v8_arm/obj/libv8_libsampler.a

out.gn/arm.release/clang_x86_v8_arm/obj/src/inspector/libinspector.a

out.gn/arm.release/clang_x86_v8_arm/obj/third_party/icu/libicui18n.a

out.gn/arm.release/clang_x86_v8_arm/obj/third_party/icu/libicuuc.a

out.gn/arm.release/clang_x86_v8_arm/obj/libv8_base.a

out.gn/arm.release/clang_x86_v8_arm/obj/libv8_nosnapshot.a

out.gn/arm.release/clang_x86_v8_arm/obj/libv8_version.a

out.gn/arm.release/clang_x86_v8_arm/obj/libv8_libplatform.a

out.gn/arm.release/clang_x86_v8_arm/obj/libv8_libbase.a

I am trying to compile a c++ fie with these libraries using NDK, and I get bunch of errors 

My Android.mk file looks like this

=================================

LOCAL_PATH := $(call my-dir)

LOCAL_MULTILIB := "both"

include $(CLEAR_VARS)

LOCAL_MODULE    := v8_base

LOCAL_SRC_FILES := $(HOME)/v8/out.gn/arm.release/clang_x86_v8_arm/obj/libv8_base.a

LOCAL_STATIC_LIBRARIES := v8_base v8_libbase v8_libplatform v8_nosnapshot

LOCAL_LDLIBS += -L$(SYSROOT)/usr/lib -llog -latomic

include $(BUILD_SHARED_LIBRARY)

My Application.mk file looks like this:

=============================

APP_ABI := armeabi armeabi-v7a

APP_PLATFORM := android-15

APP_STL=c++_static

I get these errors:

Anybody please help!!!
