Build optee_examples SHARED_LIBRARIES Error

[menghung]

Hi All

I want to use libteec.so to make SHARED_LIBRARIES
I modify the Android.mk of Helloword like this

LOCAL_PATH := $(call my-dir)

OPTEE_CLIENT_EXPORT = $(LOCAL_PATH)/…/…/optee_client/out/export

include $(CLEAR_VARS)
LOCAL_CFLAGS += -DANDROID_BUILD
LOCAL_CFLAGS += -Wall

LOCAL_SRC_FILES += host/main.c

LOCAL_C_INCLUDES := $(LOCAL_PATH)/ta/include
$(OPTEE_CLIENT_EXPORT)/include \

LOCAL_SHARED_LIBRARIES := libteec
LOCAL_MODULE := optee_example_hello_world
LOCAL_VENDOR_MODULE := true
LOCAL_MODULE_TAGS := optional
**include $(BUILD_SHARED_LIBRARY)**    ==> **include $(BUILD_EXECUTABLE) is OK but BUILD_SHARED_LIBRARY is fail**

include $(LOCAL_PATH)/ta/Android.mk

I always get the following error.

ninja: error: ‘**out/target/product/hikey960/obj_arm/lib/libteec.so.toc’**, needed by ‘out/target/product/hikey960/obj_arm/SHARED_LIBRARIES/libmhjni_intermediates/LINKED/libmhjni.so’, missing and no known rule to make it
12:47:18 ninja failed with: exit status 1

First you're missing a backslash (\) in your Android.mk

LOCAL_C_INCLUDES := $(LOCAL_PATH)/ta/include \ ==> this one
$(OPTEE_CLIENT_EXPORT)/include \

I changed include $(BUILD_EXECUTABLE) to include $(BUILD_SHARED_LIBRARY) and was able to build without issues.

[ 95% 19/20] Install: out/target/product/hikey/vendor/lib64/optee_example_hello_world.so
[100% 20/20] build out/target/product/hikey/obj/SHARED_LIBRARIES/optee_example_hello_world_intermediates/optee_example_hello_world.so.toc

Ah, have you built libteec.so first? If not, then out/target/product/hikey960/obj_arm/lib/libteec.so.toc is missing, which is required for optee_example_hello_world.so.
