__imp 使用在 mingw 下运行的 g++ 链接错误 [英] __imp link errors using g++ running under mingw

问题描述

我有一个简单的套接字程序，我正在尝试使用在 Win8 系统上的 mingw(均为最新版本)中运行的 g++ 进行编译.我遇到了常见的链接器错误

I have a simple socket program that I'm trying to compile using g++ running in mingw (both the latest versions) on a Win8 system. I'm getting the common linker errors

undefined reference to `__imp_socket'
undefined reference to `__imp_gethostbyname'

我试过添加 -lws2_32 没有运气；即它仍然找不到引用.有人可以建议我可能遗漏的其他内容吗?

I've tried adding -lws2_32 with no luck; i.e. it still can't find the references. Can someone suggest something else I might be missing?

这是完整的输出:

G:\source\kak>g++ -o ./test_client -lws2_32 test_client.C

推荐答案

尝试将 -lws2_32 放在 test_client.C 参数之后.gcc (ld) 的链接器对可链接事物的顺序很敏感，这可能是它在链接时找不到您导入的函数的原因.

Try putting the -lws2_32 after the test_client.C parameter. The linker of gcc (ld) is touchy about the order of linkable things, this is probably why it doesn't find your imported functions at link time.
