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

Question

i have a header file which contained all of the class' functions including code so the class didn't have a cpp file. everything worked. I added the cpp file and moved the function code over to that and now i get this error when compiling. the header that im getting the error in ((x86)\\microsoft sdks\\windows\\v7.0a\\include\\winnt.h(6361)) isnt even included by the file that im changing. does anyone know what the reason for this might be? i can provide code i just don't know what would be helpful.

the cpp file:

including windows.h at the top of the header file solved this issue.

Answer 1

Does the error also say PCONTEXT undefined ?

Try adding #include <Windows.h> before #include <X3DAudio.h> .

In reply to comment about unresolved external symbol :

That's because you didn't define Fisherman::SetFront in the cpp file.

Answer 2

Whole code would be helpfull. Did you remember obvious to give namespace to names of functions etc?

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

etc?

Fastest way would be reverting back to state when it worked, and not moving whole at once, but only one function at a time. Then when problem would occure you could give us that specific code or try to fix it yourself.

Answer 3

It is very possible that there is just a missed ';', somewhere before this line.

Double-check your code, remember that everything you define in a cpp file has to already be declared in your class definition.

I'd prefer to post a comment, but apparently I'm not allowed.

Anyway, as a simpler way to give us a feel of what you're trying to do, definatley post your code - it does not have to be exactly as you use, but should be a concise piece of generic code, highlighting how you are doing something. ( SSCCE ) If it really is a bug in how you typed it, it would be good to have your exact code, but put it on pastebin and provide a link so that this page doesn't end up with reams of code.

EDIT: winnt.h apparently causes all sorts of problems: Weird compile error dealing with Winnt.h it is used to provide definitions for winAPI specific headers, as far as I know. One of the solutions proposed on that thread is to get the definitions from a different windows header before including whichever header requires those definitions.
