使用 Mingw 构建 libevhtp
Building libevhtp using Mingw
我正在使用 mingw 在 windows 上构建 libevhtp，我已经使用 cmake 和 mingw 生成了 Makefile。调用 "make"-
时出现错误
fatal error: arpa/inet.h: No such file or directory
这是出现错误的 log.c。我检查过mingw
并且不包含 arpa/inet.h，并且安装程序不提供任何提供 arpa/inet.h 的库。

arpa/inet.h 是 POSIX header 而 win32 API 不支持它。 MinGW headers 只是原生 win32 headers 的重新实现，不提供额外的 POSIX 兼容性。在 Windows 上，您必须使用 winsock2.h.
您可以尝试使用 Cygwin，它包含来自 Linux 的更多内容。安装 Cygwin 将花费大量时间，并且无法保证结果。
