Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

  Snippets:

cc1plus: all warnings being treated as errors
]: [There is a warning emited by compiler. And option `D_FORTIFY_SOURCE` treat all warnings as errors.]


Answer: Issue: There is a warning emitted from the test, and the compiler option treats any warning as an error.
Resolution: In this specific case, the test are integration tests and they define their own build flags. The solution is to use

```
%undefine _auto_set_build_flags
```

at the end of `%install` section. That reset predefined build flags for `%check` phase.
