C++ - Precompiled headers issue

Question

Okay so I am writing something up in C++ and last night it was fine, I could compile perfectly w/o a problem. I saved all of my stuff and closed VS 2010 Ultimate. This morning when I went to go work on my stuff I tried recompiling and I got just over 200 errors, I couldn't figure out why so I noticed there were a few more warnings than usual and it says that it is skipping my headers.

Warning C4627: '#include <iostream>': skipped when looking for precompiled header use.

I tried disabling precompiled headers for my main .cpp but when I compile it just gives me even more errors. Is there any way to fix this?

Add #include "stdafx.h" at the the top of your cpp file, just above other include directives. — Abdullah Leghari, Sep 22 '14 at 21:52

Putting on my magic telepathic helmet, you problem is:

Your #include "myPrecompiledHeader.h" is not the first include in a file, when it should be.

I sense that the name of the precompiled header is... stdafx.h. – villintehaspam Sep 22 '14 at 21:52

You have not posted more information, though the warning says it skipped #include<iostream> because preprocessor was expecting a precompiled header file. In case of your Visual C++ project that file normally is stdafx.h, try adding it as,

#include "stdafx.h"

Add #include "stadfax.h" at the the top of your cpp file, just above other include directives.

Why doesn't disabling precompiled headers fix the problem? – David G Sep 22 '14 at 22:00
I think visual studio manages pre-compiled headers not by project but by files. So OP probably will have to disable it for all files. – Abdullah Leghari Sep 22 '14 at 22:20
