h编译错误 我在Eclipse中有一个新的C++项目。我不得不手动添加所有的include路径，我一定是搞错了什么。这是我的密码： #include <winsock2.h> int main() { return 0; }

如果可能，尝试使用7.1或7.0 SDK而不是8.0/8.1。8.0 SDK也存在类似问题。

Microsoft的Windows标题中有许多内容取决于编译器定义的预处理器符号的存在和/或值。也许您缺少了一些对构建至关重要的功能？我通常会发现，在错误发生的位置附近搜索会找到丢失的符号，通常是在跟踪一两个typedef的来源之后。是否可以混合使用7.x和8.x SDK？8.1的winnt.h导致了我的问题，而7.1没有SDL2.0.3所需的winapifamily.h！所以我可以使用SDL的当前版本，也可以使用网络支持。。。不公平。
