You can often set treat_warnings_as_errors=false to not treat output as failure (useful when developing locally).

解决方案

在out/Default/args.gn 的编译文件中添加 fatal_linker_warnings=false

# Build arguments go here.
# See "gn args <out_dir> --list" for available build arguments.
target_os = "android"
target_cpu = "x86"
is_debug = false 
system_webview_package_name = "com.android.webview"
fatal_linker_warnings = false
treat_warnings_as_errors=false
