错误 C2146：语法错误：标识符'ContextRecord'之前缺少';'

Question

我有一个头文件，其中包含所有类的函数，包括代码，所以类没有CPP文件。一切工作。我添加了cpp文件，并将函数代码移动到那里，现在我在编译时得到这个错误。我在((x86)microsoft sdk windowsv7.0aincludewinnt.h(6361))中得到错误的标头甚至不包括在我更改的文件中。有人知道这可能是什么原因吗?我可以提供代码，我只是不知道什么会有帮助。

在头文件的顶部包含windows.h解决了这个问题。

Answer 1

错误是否也显示PCONTEXT undefined ?

尝试在#include <X3DAudio.h>之前添加#include <Windows.h>

关于unresolved external symbol评论的回复:

这是因为您没有在cpp文件中定义Fisherman::SetFront。

Answer 2

完整的代码将是有帮助的。你还记得给函数的名字命名空间吗?

class A { void foo() { } };
=>
class A { void foo(); }
void A::foo() { ... }

等等?

最快的方法是在它工作时恢复到状态，而不是一次移动整个函数，而是一次只移动一个函数。当问题出现时，你可以给我们具体的代码，或者试着自己修复它。

Answer 3

很可能在这行之前的某个地方漏了一个';'。

仔细检查你的代码，记住你在cpp文件中定义的所有东西都必须已经在你的类定义中声明过。

我想发表评论，但显然我不被允许。

无论如何，作为一种更简单的方式，让我们感受到你在做什么，一定要发布你的代码——它不必完全是你使用的，但应该是一段简洁的通用代码，突出你是如何做某事的。(SSCCE)如果它真的是一个错误在你如何键入它，它会很好有你的确切代码，但把它放在pastebin上，并提供一个链接，这样这个页面不会结束与大量的代码。

编辑:

winnt.h显然会导致各种各样的问题:处理winnt.h时出现奇怪的编译错误据我所知，它是用来为winAPI特定的头提供定义的。在该线程中提出的解决方案之一是在包含需要这些定义的头文件之前从不同的窗口头文件中获取定义。
