+# 1、问题现象
+
+`[   95s] clang: error: argument unused during compilation: '-fstack-clash-protection' [-Werror,-Wunused-command-line-argument]`
+
+# 2、问题根因分析
+
+[macOS arm64 support · Issue #183 · GrapheneOS/hardened_malloc (github.com)](https://github.com/GrapheneOS/hardened_malloc/issues/183)
+
+参考这个Issue可知，`The issue with -fstack-clash-protection is that it's not implemented on arm64 yet.`，即aarch64下`-fstack-clash-protection`特性还未在clang中实现。因此会出现报错。
+
+# 3、问题修改建议
+
+不必修改。
+
+openEuler社区会默认将这个error降级为warning，实际情况中不影响构建。
