HDI接口驱动和服务编译错误，ACTION //build/ohos/packages:collect_notice_files__phone(//build/toolchain/ohos:ohos_clang_arm)

编译由IDL生成的xxx_driver和xxx_service的库时出现错误

1.在做好驱动，开始封装HDI接口时，使用IDL，编译生成几个文件

其中最重要的四个途中红框框中，其中myled_interface_driver.cpp基本已经实现，只修改了最后“.moduleName =”字段，其他没有更改。完善了myled_interface_service.cpp。

2.进行编译时，BUILD.gn如下

进行编译时已完整生成相应的.so文件，但是在最后几步出现以下问题：

3.问题所在，当我将ohos_shared_library("libmyled_interface_service_1.0")和ohos_shared_library("libmyled_interface_service_1.0")修改为ohos_shared_library("myled_interface_service_1.0")和ohos_shared_library("myled_interface_service_1.0")就可以编译成功。两者生成的.so文件一模一样。

4.最终尽管编译成功，host服务还是起不来，不知道是不是因为这个原因。请大佬们解惑！
