c++ - 如何将 Winsock2 的 Ws2_32.lib 添加到 Windows 10 上的 MinGW-w64 C 项目的生成文件中？

Question

我需要在 Windows 10 上向我现有的 MinGW-w64 应用程序添加一个侦听套接字，但在 makefile 中看不到任何有关库的部分。

我将 docs.microsoft 中的Winsock 服务器源代码添加到我的应用程序中，但现在需要为 Winsock2 添加 .lib。我需要修改makefile以链接到winsock2 lib中，我相信它是：Ws2_32.lib，但在makefile中看不到任何关于libs的部分。

我在一个空的 Visual C++ 项目中尝试了这个源代码，它构建得很好。
在此源代码中，这些行指定了 Winsock2 库：

// Need to link with Ws2_32.lib
#pragma comment (lib, "Ws2_32.lib")
// #pragma comment (lib, "Mswsock.lib")

为了构建我的 MinGW-w64，我使用这个：

mingw32-make OS=win

这是生成文件

# preferred in some situations where standards conflict, unless one or more of _SVID_SOURCE,
# _POSIX_SOURCE, _POSIX_C_SOURCE, _XOPEN_SOURCE, _XOPEN_SOURCE_EXTENDED, or _GNU_SOURCE is defined,
# in which case BSD definitions are disfavored. Since glibc 2.19, _BSD_SOURCE no longer causes BSD
# definitions to be preferred in case of conflicts. Since glibc 2.20, this macro is deprecated.
# It now has the same effect as defining _DEFAULT_SOURCE, but generates a compile-time warning
# (unless _DEFAULT_SOURCE is also defined). Use _DEFAULT_SOURCE instead.
# To allow code that requires _BSD_SOURCE in glibc 2.19 and earlier and _DEFAULT_SOURCE in glibc
# 2.20 and later to compile without warnings, define both _BSD_SOURCE and _DEFAULT_SOURCE.

“重复”不包含答案。

这是有效的答案... <<<<<<<<<<<<<<<<<<<<<<<<<<<

我改变了这个：

  ifeq ($(ARCH),64)
    override LDFLAGS += -static lib/libaox_static_win64.a -lstdc++
    TARGET:=WIN64
  else
    override LDFLAGS += -static lib/libaox_static_win32.a -lstdc++
    TARGET:=WIN32
  endif

对此：

  ifeq ($(ARCH),64)
    override LDFLAGS += -static lib/libaox_static_win64.a -lstdc++
    override LDFLAGS += -static lib/Ws2_32.lib -lstdc++
    TARGET:=WIN64
  else
    override LDFLAGS += -static lib/libaox_static_win32.a -lstdc++
    override LDFLAGS += -static lib/Ws2_32.lib -lstdc++
    TARGET:=WIN32
  endif
