note: in expansion of macro 'A_MACRO'
提问by nowox
I have hundred of warnings like this when build with gcc:
使用gcc以下命令构建时，我有数百个这样的警告：
foo.c:2690:5: note: in expansion of macro ‘PUT_UINT32'
PUT_UINT32(state, digest, 0);
How can I get rid of them?
我怎样才能摆脱它们？

I assume you are using clang: when clangdetects an error or a warning in code expanded from a macro, it outputs one line for each macro whose expansion leads to the offending code. Fix the errors and warnings in the final code and these messages will disappear.
我假设您正在使用clang：当clang在从宏扩展的代码中检测到错误或警告时，它会为每个扩展导致违规代码的宏输出一行。修复最终代码中的错误和警告，这些消息将消失。
