In Visual Studio 2015, I have a C++/CLI project with the following error:
"fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "stdafx.h"' to your source?"
I turned off precompiled headers in the project options but it keeps giving me the same error. I even removed the name of the precompiled header file but it still says "stdafx.h".
Edit:
Yes, every source file indivuduially doesn't have it enabled.
Ok. Hans Passant found out what was happening:
The build configuration that I used to build it still had precompiled headers enabled.
You may have disabled it for the project, but each individual source file can have it's own specific compiler settings. It's also possible you disabled pre-compiled headers for a specific source file, erroneously mistaking that action for a project wide setting.
For each individual C/C++ file in Solution Explorer, right click on it and select "Properties". Under C/C++ -> Precompiled Headers, make sure the Precompiled Header setting is "Not using Precompiled Headers".
The right click on your Project name in Solution Explorer and select "Properties as well" Double-check that the project settings are the same.
And if there's a stdafx.cpp file, it likely has the "Create Precompiled Header" setting. You can typically remove this file if it doesn't have any relevant code in it.
Repeat all the same steps for each Solutions configuration (e.g. both Debug and Release).
I met the same problem (turned off precompiled in project properties but the error remains).
Solution:
open .proj file with any text editor and search for
<PrecompiledHeader>Use</PrecompiledHeader>
you will see that there are still some properties set to use it. Just replace word "Use" with "NotUsing" and problem fixed.
Microsoft Visual Studio 2015:
Right click on solution -> Configuration Properties -> C/C++ -> Precompiled Headers -> Precompiled Header => Not Using Precompiled Headers
In my case, I found the pch.h still set in: c++ -> advanced -> forced include files.
Anyhow, Andrew's solution is still the best. Just open the proj. file in a text editor and ctrl-f search for the filename causing the issue. Much easier than skimming through all the properties in vs.

I am Using VS Community 2015 to create C++ Console applications
I am trying to stop using pre-compiled headers.
I have deleted #include "stdafx.h" , and the stdafx .h and cpp files.
In the project properties pages I selected
Not Using Precompiled Headers
I tried clean, rebuild, nothing works.
VS keeps looking for the precompiled headers:
1>ConsoleApplication2.cpp(7): fatal error C1010: unexpected end of
file while looking for precompiled header. Did you forget to add
'#include "stdafx.h"' to your source?
Anyone have a solution?
VS project properties can be overridden on individual source file level. Inspect the properties of ConsoleApplication2.cpp (and other source files where you get errors) and make sure their PCH-related properties are not bolded, i.e. that they are in the state "inherit from parent or project defaults."
Also make sure that you are editing properties for the configuration (e.g. "Debug") which you are actually building. The VS property dialog allows you to edit properties for any configuration, not just the one currently selected in the solution-wide configuration combo. What I usually do is to always set the dialog's configuration to the "Active" option before exiting it, so that when I open it, I don't have to check.
I have seen all the articles on web, but nothing seems to resolve my issue.
Someone plz help me out on this.
I am using debug mode, VS 2010, .net 4 Framework.
In project properties,
CLR is on in general
CLR in on in C++->general
All .cpp files are having use (/yu) in precompiled hearder settings
stdafx.cpp has /yc (create) with clr on
I had the some problem.
Validate that all the C++ files properties (right click on the file in the solution explorer and Properties) are mark with "Common Language RunTime Support" as "/clr"
This error occurs when another version of the compiler has created the PCH file or the PCH is corrupt. Try cleaning the solution or simply rebuilding.
Can someone please help me understand how to build the open source Docfrac C++ Eclipse project with Visual Studio 2012?

UPDATE 1:
When building project in VS 2012, I get:
Unexpected end of file while looking for precompiled header. Did you forget to add '#include "pch.h"' to your source?
UPDATE 2: Got past above issues thanks to Rowland.
Now i get, could not open #include vcl.h. No such file or directory.
CLOSING COMMENTS:
Unfortunately, what I wanted to achieve is not directly possible. Thanks to Rowland for pointing me in the right direction.
For the error relating to precompiled headers, select the source code files (.cpp or .c) that you added to the project in the Solution Explorer. Then right-click, choose Properties. Then in the C/C++ section under Precompiled Headers, select the option that says "Not using precompiled headers". Rebuild and bingo.
Alternatively, you can right-click the project itself and set it for all files.
I read the documentation in MSDN, but in the end I didn't get a clear idea what is the practical difference between them, exactly. Both seem to require stdafx.h to be added at the top of every *.cpp file.
I'm using VS2008.
Can anyone help clear things up?
Short summary of how to use PCH files in Visual Studio:
All cpp files in the project have to include stdafx.h (you can change this to something else if you wish)
Select project in Solution Explorer and in Properties -> C++ -> Precompiled Headers set 'Create/Use precompiled headers' to 'Use'. Hit Apply
While the Property Pages are still shown select stdafx.cpp in solution explorer and set the value to 'Create'
Well, I think that you must first understand the purpose of precompiled headers. In large projects, it can take ages to process all the headers required by a single client extension for example, so some people prefer to distribute the .pch files along with their libraries. In order to generate the .pch files, you use the /Yc compiler flag and the person who wants to consume your library will set the /Yu flag. See here and here for details.
I've successfully installed M$ VC2010 and start writing simple programs using it.
I am very annoyed from the #include<stdafx.h>, So is there any way to compile and run programs without it???
It's for pre-compiled headers. Don't use pre-compiled headers, don't include it.
Goto Project Settings->Precompiled Headers.
Select Not using precompiled headers.
You can also turn off precompiled headers per file.
Setting this in VS Express C++ 2012 is as follows:
In Project Explorer right-click on .cpp file, select Properties.
On the left pane select Configuration Properties/C++/ Precompiled
Headers
Now, on the right pane there is 'Precompiled Header' value which
you can change from Use /Yu to :
'Not Using Precompiled Headers'
Cheers
Of course, just go to Project Settings, C/C++ → Precompiled Headers, and choose "Not Using Precompiled Headers".
BTW: On large projects using precompiled headers may significantly decrease build time.
When you create your project, create an empty project.
For now, you can disable it in Project Settings.
