Adding an Include path from an upper Android.mk into a subdir module

The root has an Android.mk, the Core folder has an Andoird.mk file and Core/Base has an Android.mk file.

Root Andoird.mk

CORE_ROOT_PATH := $(abspath $(call my-dir))
CORE_SRC_PATH := $(abspath $(call my-dir))/Core
CORE_VENDOR_PATH := $(abspath $(call my-dir))/Vendor
include $(call all-subdir-makefiles)

Core Android.mk

include $(call all-subdir-makefiles)

Base Andoird.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
$(warning CORE VENDOR = $(CORE_VENDOR_PATH))
LOCAL_C_INCLUDES := $(CORE_ROOT_PATH)\
              $(CORE_VENDOR_PATH)/Eigen

LOCAL_SRC_FILES := $(call all-cpp-files-under, . )

LOCAL_MODULE := coreBase

include $(BUILD_STATIC_LIBRARY)

So ./Core/Base needs to some include files defined in ./Vendor/Eigen/

I want to add ./Vendor/Eigen as a LOCAL_C_INCLUDES search path for the Base module but this is failing with the line

build/core/binary.mk:1522: error: vendor/rylo/Core/Core/Base/Android.mk: coreBase: C_INCLUDES must be under the source or output directories: /home/kartik/Projects/qcom/vendor/rylo/Core /home/kartik/Projects/qcom/vendor/rylo/Co

It looks like I can’t use LOCAL_C_INCLUDES to add an include path that is outside of the Module Android.mk root path. How should I bring in that search path?

Thanks

Okay Silly me... I figured out after reading build/core/build-system.html that LOCAL_C_INCLUDES are specified releative to the TOP Android file. Please ignore.

Thanks

How did you resolve this problem with C_INCLUDES, I put logs into mk file and got problem C_INCLUDES when Android.mk tries

include $(BUILD_STATIC_LIBRARY)

Have solution for this problem ?
