1. 更改源码目录名引发的错误

错误一： “EDK_TOOLS_PATH: /home/sun/Project/Android10_Project/bootable/bootloader/edk2/BaseTools”

(1) 问题描述：
EDK_TOOLS_PATH的路径不对，同步代码的时候我建的文件夹确实叫做"Project"，但是后来我给改成了"project"，没想到android的编译系统这么弱智，这都同步不了

(2) 解决办法：
进入EDK_TOOLS_PATH的上一级目录，然后执行下面命令

rm -rf Conf/BuildEnv.sh
unset EDK_TOOLS_PATH
./edksetup.sh BaseTools

错误二： “make[3]: *** No rule to make target ‘/home/sun/Project/Android10_Project/prebuilts/clang/host/linux-x86/clang-r353983c1/lib64/clang/9.0.3/include/stdint.h’, needed by ‘BasePeCoff.o’. Stop.”

(1) 问题描述：
这个其实和上面的错误一个道理，都是旧目录名称没有更新(旧目录叫“Project”，新目录叫“project”)

(2) 解决办法：
上个错误已解决的基础上，在EDK_TOOLS_PATH目录，执行make clean即可。

2. 添加VNDK库(Vendor Native Development Kit)报错

[ 5% 634/10974] build out/target/product/trinket/obj/PACKAGING/vndk_intermediates/check-list-timestamp FAILED: out/target/product/trinket/obj/PACKAGING/vndk_intermediates/check-list-timestamp /bin/bash -c "(( diff --old-line-format=\"Removed %L\" --new-line-format=\"Added %L\" --unchanged-line-format=\"\" build/make/target/product/gsi/29.txt out/target/product/trinket/obj/PACKAGING/vndk_intermediates/libs.txt || ( echo -e \" error: VNDK library list has been changed.\\n\" \" Changing the VNDK library list is not allowed in API locked branches.\"; exit 1 )) ) && (mkdir -p out/target/product/trinket/obj/PACKAGING/vndk_intermediates/ ) && (touch out/target/product/trinket/obj/PACKAGING/vndk_intermediates/check-list-timestamp )" Added VNDK-core: libturbo_jpeg.so error: VNDK library list has been changed. Changing the VNDK library list is not allowed in API locked branches.

问题描述： 看报错内容，可以知道是用diff命令对29.txt和libs.txt的内容进行了逐行比较，因两个文件内容不一致而导致的问题。至于为什么不一样，那是因为由于项目原因，需要添加一个名为libturbo_jpeg的VNDK动态库，在编译的时候新库名字被写到了libs.txt，而29.txt还是原先内容
动态库的创建是在external/libjpeg-turbo/Android.bp中，如下

cc_library {
    name: "libturbo_jpeg",
    host_supported: true,
    vendor_available: true,  //VNDK库需要设置为true
    vndk: {
        enabled: true,      //VNDK库需要设置为true
    },
    defaults: ["libjpeg-defaults"],
    export_include_dirs: ["."],
    target: {
        windows: {
            enabled: true,
        },
    },
    srcs: [
        "jdatadst-tj.c",
        "jdatasrc-tj.c",
		"turbojpeg.c",
		"transupp.c",
		"rdbmp.c",
		"rdppm.c",
		"wrbmp.c",
        "wrppm.c",
            ],
    cflags: [
        "-DBMP_SUPPORTED",
        "-DPPM_SUPPORTED",
        "-Werror",
        "-Wno-unused-parameter",
    ],
}

解决方法：
将libs.txt的内容直接全部拷贝到29.txt中即可

3. 头文件被重复包含

FAILED: build/make/core/main.mk:1158: warning: "xxf : _modules_xxx_cut" = build/make/core/Makefile:76: warning: Duplicate header copy: out/target/product/myproject/obj/include/mycarcam/mycarcam.h build/make/core/Makefile:76: warning: _ Using vendor/qcom/proprietary/mm-camera/ais/API/inc/mycarcam.h build/make/core/Makefile:76: warning: __ from vendor/qcom/proprietary/mm-camera/ais/libais_client.mk build/make/core/Makefile:76: warning: _ Ignoring vendor/qcom/proprietary/mm-camera/ais/API/inc/mycarcam.h build/make/core/Makefile:76: warning: __ from vendor/qcom/proprietary/mm-camera/ais/libais_client.mk build/make/core/Makefile:76: warning: Duplicate header copy: out/target/product/myproject/obj/include/mycarcam/mycarcam_types.h build/make/core/Makefile:76: warning: _ Using vendor/qcom/proprietary/mm-camera/ais/API/inc/mycarcam_types.h build/make/core/Makefile:76: warning: __ from vendor/qcom/proprietary/mm-camera/ais/libais_client.mk build/make/core/Makefile:76: warning: _ Ignoring vendor/qcom/proprietary/mm-camera/ais/API/inc/mycarcam_types.h build/make/core/Makefile:76: warning: __ from vendor/qcom/proprietary/mm-camera/ais/libais_client.mk build/make/core/Makefile:95: error: duplicate header copies are no longer allowed. For more information about headers, see: https://android.googlesource.com/platform/build/soong/+/master/docs/best_practices.md#headers.

问题描述： 看error那行，意思是不再允许拷贝重复的头文件，然后我们再看上面的warning，发现编译过程中mycarcam.h和mycarcam_types.h被重复拷贝了，这是不被允许的（不过我试过只重复一个文件就没问题，费解。。。）

解决方法： 经过排查是mk文件中，这两个头文件被重复拷贝了，可根据项目实际情况进行添加条件避免重复拷贝

3. 无法链接库文件，库文件丢失

[ 99% 365/366] finishing build rules ... FAILED: vendor/qcom/proprietary/pis/test/test_util/Android.mk: error: "libpis_test_util (native:platform) can not link against libimg (native:vendor)" vendor/qcom/proprietary/pis/test/test_util/Android.mk: error: "libpis_test_util (SHARED_LIBRARIES android-arm64) missing libjpeg (SHARED_LIBRARIES android-arm64)" You can set ALLOW_MISSING_DEPENDENCIES=true in your environment if this is intentional, but that may defer real problems until later in the build. ... build/make/core/main.mk:959: error: exiting from previous errors. 14:45:48 ckati failed with: exit status 1 #### failed to build some targets (02:46 (mm:ss)) ####

错误一： “libpis_test_util (native:platform) can not link against libimg (native:vendor)”
(1) 错误分析：
  这个error表达的是库libpis_test_util(native:platform)不能链接库libimg (native:vendor)。看下面两个Android.mk文件，libpis_test_util(native:platform)用链接系统库的方式链接了vendor库，这个肯定是不行。

libpis_test_util的Android.mk:

...//省略
LOCAL_MODULE := libpis_test_util
LOCAL_HEADER_LIBRARIES := libtest_headers
LOCAL_SHARED_LIBRARIES += libtest libimg libjpeg      //LOCAL_SHARED_LIBRARIES这个flag是用来链接系统库的
...//省略

libimg的Android.mk:

...//省略
include $(CLEAR_VARS)
LOCAL_MODULE        := libimg
LOCAL_MODULE_CLASS  := SHARED_LIBRARIES
LOCAL_MODULE_SUFFIX := .so
LOCAL_STRIP_MODULE  := false
LOCAL_MULTILIB      := 64
LOCAL_MODULE_OWNER  := qcom
LOCAL_MODULE_TAGS   := optional
LOCAL_SRC_FILES     := ../../.././target/product/xxx/system/lib64/libimg.so
LOCAL_MODULE_PATH   := $(PRODUCT_OUT)/system/lib64
LOCAL_PROPRIETARY_MODULE := true     //这里可以看到libimg库是属于proprietary的，也就是vendor的模块
include $(BUILD_PREBUILT)
...//省略

(2) 解决方法：
 把libimg的Android.mk中的LOCAL_PROPRIETARY_MODULE置为false，或者把libpis_test_util的Android.mk中的LOCAL_SHARED_LIBRARIES改为LOCAL_LDFLAGS(就是把链接方式由链接系统库改为链接第三方库)

错误二： “libpis_test_util (SHARED_LIBRARIES android-arm64) missing libjpeg (SHARED_LIBRARIES android-arm64)”
(1) 错误分析：
  这个error表达的是编译系统没有找到libjpeg库，通过查看是没有为libjpeg库添加编译规则

(2) 解决方法：
  在对应的Android.mk中加入编译规则，对应内容如下所示：

include $(CLEAR_VARS)
LOCAL_MODULE        := libjpeg
LOCAL_MODULE_CLASS  := SHARED_LIBRARIES
LOCAL_MODULE_SUFFIX := .so
LOCAL_STRIP_MODULE  := false
LOCAL_MULTILIB      := 64
LOCAL_MODULE_OWNER  := qcom
LOCAL_MODULE_TAGS   := optional
LOCAL_SRC_FILES     := ../../.././target/product/xxx/system/lib64/libjpeg.so
LOCAL_MODULE_PATH   := $(PRODUCT_OUT)/system/lib
include $(BUILD_PREBUILT)
