MinGW 链接器错误:winsock

MinGW linker error: winsock(MinGW 链接器错误:winsock)

问题描述

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:

I am using MinGW compiler on Windows to compile my C++ application with sockets. My command for linking looks like:

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

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:

but in both case I get this error:

请问您知道问题出在哪里吗?

Do you have any ideas where the problem can be, please?

推荐答案

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.

Put the -lws2_32 AFTER the list of object files - GCC searches libraries and object files in the order they appear on the command line.

只是为了帮助其他观众:

Just to help the other viewers out there:

gcc hello.c -o hello.o -lws2_32
