C 编译时出现Libev错误

我试图编译一个带有gcc-g-Wall-Wextra-DNDEBUG-pedantic-ansi标志的代码，并使用libev库。我在eclipse中遇到以下错误：

我已经在ubuntu中安装了libev dev包。

您的

-ansi

标志会导致编译器只接受C89代码，并且只在标准头文件（glibc/gcc）中启用C89功能

---

libev不是由严格的c89编译器编译而成的，它至少需要一个posix（或者可能是win32）系统，而且可能还使用了一些c99功能。

感谢您的回复。我昨天在libev的IRC频道上问它是否符合ansic标准。他们告诉我是的。所以我没有错。感谢您的确认。如果您可以添加此问题的解决方案，那么它实际上会有所帮助。：-）@jparthj问题是

-ansi

标志，解决方法是不使用-ansi或类似标志。好的，我知道了，但在我的情况下，我没有使用-ansi标志，问题存在。@jparthj然后，假设是完全相同的错误，您使用了-std=c99或类似的东西。或者你在一个相当奇怪的平台上，或者你的程序有一些与libev或标准libc头混乱的定义。
