构建Android源代码时如何设置TARGET_NO_KERNEL = true

Question

这是构建

Android 14

源代码时的警告消息：

build/make/core/Makefile:4889: warning: Neither INSTALLED_KERNEL_TARGET nor INSTALLED_BOOTIMAGE_TARGET is defined when PRODUCT_O
TA_ENFORCE_VINTF_KERNEL_REQUIREMENTS  is true. Information about the updated kernel cannot be built into OTA update package. You
 can fix this by: (1) setting TARGET_NO_KERNEL to false and installing the built kernel to out/target/product/generic_arm64/kern
el, so that kernel information will be extracted from the built kernel; or (2) Add a prebuilt boot image and specify it in BOARD
_PREBUILT_BOOTIMAGE; or (3) extracting kernel configuration and defining BOARD_KERNEL_CONFIG_FILE and BOARD_KERNEL_VERSION manua
lly; or (4) unsetting PRODUCT_OTA_ENFORCE_VINTF_KERNEL_REQUIREMENTS manually.

这里是源代码：

build/make/core/Makefile

ifneq ($(strip $(TARGET_NO_KERNEL)),true)
  ifneq ($(strip $(BOARD_KERNEL_BINARIES)),)
    INSTALLED_KERNEL_TARGET := $(foreach k,$(BOARD_KERNEL_BINARIES), \
      $(PRODUCT_OUT)/$(k))
  else
    INSTALLED_KERNEL_TARGET := $(PRODUCT_OUT)/kernel
  endif
else
  INSTALLED_KERNEL_TARGET :=
endif

设置

TARGET_NO_KERNEL = true

的正确方法是什么？那么在哪里设置呢？

Answer 1

要将

TARGET_NO_KERNEL

设置为

true

，您可以将以下行添加到您的

BoardConfig.mk

文件中：

TARGET_NO_KERNEL := true

这会将

TARGET_NO_KERNEL

标志设置为

true

。您还可以通过添加以下行在

Android.mk

文件中设置此标志：

LOCAL_KERNEL := <path-to-your-kernel>

您可以将

<path-to-your-kernel>

替换为内核的路径。这会将构建的内核安装到

out/target/product/generic_arm64/kernel

，以便从构建的内核中提取内核信息1.
