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:

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

而我也试过了

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'

你有什么想法可以解决问题吗？

Answer 1

将-lws2_32AFTER 放在目标文件列表中 - 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

Answer 2

with mingw on eclipse:菜单 - Projekt - 属性 - c/c ++构建 - 设置:注册"工具设置" - MinGW C链接器 - 其他:下部"其他对象"添加:"D:\ Programmierung\mingw\lib\libwsock32.a"例如.libwsock32.a上没有其他任何属性需要,特别是在库条目中没有.也没有与此Lib有关的标志.
