1、场景说明

使用的oh 3.2.2-RELEASE版本代码，因为编译其它架构的需要升级aarch64交叉编译工具链版本到clang 16.0.0，编译qemu-arm64-linux-min模拟产品。

首先，使用官方提供的prebuilt的clang 12.0.1能够正常构建。

2、报错信息

hb set选择qemu-arm64-linux-min，hb build构建，期间还处理了一些新版clang编译选项差异导致的问题，最终卡在了以下这个init链接报错。

3、问题

这个LIBINIT_STUB_VERSIONSCRIPT符号是在哪里定义的？搜索了//base/startup目录下所有文件都没有找到。SystemReadParam等符号是可以从源代码中找到的。当然这个报错也有点不明确，在链接时到底是哪个符号没有找到。

=========分隔线 20230721 10:20=============

找到这个LIBINIT_STUB_VERSIONSCRIPT符号是在哪里使用了。查看//build/ohos/native_stub/native_stub.gni文件中定义（L231）的模板ohos_native_stub_versionscript的流程，它会生成一个version script文件来控制ohos_executable或ohos_shared_library目标对外输出的符号。

在日志中，这个version script文件是通过-Wl,--version-script=gen/base/startup/ini
t/interfaces/innerkits/init_module_engine/libinit_stub_versionscript.map.txt 这个参数传递给链接器的。这个文件的内容如下：

LIBINIT_STUB_VERSIONSCRIPT {
  global:
        SystemWriteParam;
        SystemReadParam;
        LoadParamsFile;
        SplitString;
        AddCmdExecutor;
        RemoveCmdExecutor;
        HookMgrAdd;
        GetBootStageHookMgr;
        InitAddGlobalInitHook;
        InitAddPreParamServiceHook;
        InitAddPreParamLoadHook;
        InitAddPreCfgLoadHook;
        InitAddPostCfgLoadHook;
        InitModuleMgrInstall;
        InitModuleMgrUnInstall;
        StartupLog;
        DoJobNow;
        GetServiceExtData;
        UpdateMiscMessage;
        AddRebootCmdExecutor;
  local:
  *;
};

那么，问题就是链接时没有找到SystemReadParam等符号，应该是缺少了定义这些符号的.o或者库文件。

===========分隔线 20230721 16:05=========================

按照@c_c8008的提示，清理重新编译后还是相同报错，不过单独执行Link命令时，参数有差异，已经包含了libinit_module_engine.so库，但是仍然报找不到这几个符号。

4、结论

的确是clang 16.0.0的原因，lld修改了一个关于version script的选项的默认值，如果引用的符号没有定义会发出一个warning，而工具链默认是开启了-Werror的，会把所有的warning转换成error。

其实，nm检查clang 12.0.1成功编译的init可执行程序的符号表，也找不到Init前缀的这些，但是SystemReadParam是有的。
