我正在浏览Android开源项目makefile,我看到了包含另一个makefile的两种不同方式.例如,master/build/target/product/aosp_arm64.mk有这些行:
PRODUCT_COPY_FILES += frameworks/native/data/etc/android.hardware.ethernet.xml:system/etc/permissions/android.hardware.ethernet.xml
$(call inherit-product, $(SRC_TARGET_DIR)/product/core_64_bit.mk)
$(call inherit-product, $(SRC_TARGET_DIR)/product/aosp_base_telephony.mk)
$(call inherit-product, $(SRC_TARGET_DIR)/board/generic_arm64/device.mk)
include $(SRC_TARGET_DIR)/product/emulator.mk
PRODUCT_NAME := aosp_arm64
PRODUCT_DEVICE := generic_arm64
PRODUCT_BRAND := Android
PRODUCT_MODEL := AOSP on ARM arm64 Emulator
$(call inherit-product ...)线和include ...线之间有什么区别？
