cpp 版本“搜索列表结束”

  • 772

当我检查cpp版本时，它向我显示了这条消息：

此消息是错误还是警告？，我能做些什么来解决它？

    它既不是错误也不是警告——它是详细的输出，包括预处理器搜索路径。来自man cpp：

       -v  Verbose mode.  Print out GNU CPP's version number at the beginning
       of execution, and report the final form of the include path.

    如果您只想要版本信息，您可以使用cpp --version：

       -version
   --version
       Print out GNU CPP's version number.  With one dash, proceed to
       preprocess as normal.  With two dashes, exit immediately.
