我需要另一个有个好眼睛的人来告诉我我在这里做错了。
我必须在我的设备上升级U-boot引导加载程序,自然地,我不得不重新安装好一切。但是目前我无法像以前那样构建AOSP系统。我将从错误消息开始,并写下我的思考过程:
的Android.mk文件。target Symbolic: fw_printenv (out/target/product/board/symbols/system/bin/fw_printenv) target Strip: fw_printenv (out/target/product/board/obj/EXECUTABLES/fw_printenv_intermediates/fw_printenv) Install: out/target/product/board/system/bin/fw_printenv target Executable: test_executer (out/target/product/board/obj/EXECUTABLES/test_executer_intermediates/LINKED/test_executer) external/utils/production/set_display_orientation.cpp:81: error: undefined reference to 'fw_printenv(int, char**, int, env_opts*)' external/utils/production/set_display_orientation.cpp:57: error: undefined reference to 'fw_setenv(int, char**, env_opts*)' external/utils/production/set_display_orientation.cpp:65: error: undefined reference to 'fw_printenv(int, char**, int, env_opts*)' collect2: error: ld returned 1 exit status
因此出现链接器错误。而且我的代码找不到其他模块中定义的功能。因此,让我们看一下负责[[set_display_orientation.cpp

include $(CLEAR_VARS)

LOCAL_SRC_FILES := test_executer.cpp \

现在错误消息说有一个。但是这些功能在bootable / bootloader / uboot-imx / tools / env中定义,这些功能包含在对fw_printenv(),fw_setenv()和fw_printenv()的未定义引用
LOCAL_C_INCLUDES += bootable/bootloader/uboot-imx/tools/env
中,它们是LOCAL_STATIC_LIBRARIES += libfw
的一部分。为了完整起见,我还将包括负责[[libfw的Android.mk文件,它是U-Boot的一部分。LOCAL_PATH := $(call my-dir)

有人可以指出我在哪里出问题了。我已经阅读了在线文档(https://developer.android.com/ndk/guides/android_mk),以及上,下stackoverflow。我真的迷失了这个。我需要另一个有个好眼睛的人来告诉我我在这里做错了什么。我必须在我的设备上升级U-boot引导加载程序,自然地,我不得不再次使事情变得合适。但是目前我...
