MinGW 链接器错误：winsock

Question

我在 Windows 上使用 MinGW 编译器来编译带有套接字的 C++ 应用程序。我的链接命令如下所示：

 g++.exe -Wall -Wno-long-long -pedantic -lwsock32 -o dist/Windows/piskvorky { there are a lot of object files }

我也试过

g++.exe -Wall -Wno-long-long -pedantic -lws2_32 -o dist/Windows/piskvorky { there are a lot of object files }

但在这两种情况下，我都会收到此错误：

 build/Windows/MinGW-Windows/src/utils/tcpunit.o:tcpunit.cpp:(.text+0x33): undefined reference to `closesocket@4'
build/Windows/MinGW-Windows/src/utils/tcpunit.o:tcpunit.cpp:(.text+0xd0): undefined reference to `send@16'

请问您有什么想法可以解决问题吗？

Answer 1

将 -lws2_32 放在目标文件列表之后 - GCC 按照它们在命令行中出现的顺序搜索库和目标文件。

只是为了帮助其他观众：

 gcc hello.c -o hello.o -lws2_32

在：

菜单-项目-属性-c/c++Build-设置：注册“工具设置”-MinGW C++链接器-杂项：下部“其他对象”

添加：来自 MinGW 的 bin 文件夹的 libwsock32.a 。
