在Objective C代码上运行RecursiveASTVisitor程序时，我不断收到此警告warning: unknown warning option '-Wno-receiver-is-weak'; did you mean '-Wno-receiver-expr'? [-Wunknown-warning-option]
warning: unknown warning option '-Wno-receiver-is-weak'; did you mean '-Wno-receiver-expr'? [-Wunknown-warning-option]
但是我没有在启用警告的情况下编译它，或者在我的代码中有任何警告选项。
错误警告来自何处以及如何禁用它？
