Any ideas what went wrong?
Thanks for the help.
Your game mode sourcefile is including a header that is incorrect in some way. I see a reference to line 228 but I'm unsure if that's in your game mode or in an included header.

those the three errors i got when i try to build in visual studio
in context to building the project, which of these build descriptions fit your situation?
Is this during:
the initial project opening ie: "build agora modules?"
packaging/building the project to test a standalone build.
Thanks!
Im new to UnrealEngine but I have worked with unity before. im trying to create a new unreal engine file but I keep getting this error every time I try (Can not compile, basically):
The project could not be compiled. Would you like to open it in Visual Studio?

I have visual studio downloaded and when I try to open it in Visual Studio, I get a build error.
please help :)
Please take a look at
https://docs.unrealengine.com/latest/INT/Programming/Development/VisualStudioSetup/
and check that you are using the correct Visual Studio version.
Also, is there a reason that you are using Unreal Engine 4.10 instead of the newest version, even though you are just starting with UE and, I assume, you don't have any previous projects?
I recently installed the most recent version of UE on my Windows 7 and made a new empty C++ project. After creating the project it gave me an error saying it failed to compile. I opened the project in VS to manually compile it and this is the output I got.
I looked online but got no answers.
EDIT: I use these headers with no issues when compiling non-UE projects.

The part that really confuses me is that it apparently can't open new.h and windows.h though Visual Studio has no problem opening the file when I check where they were included.
After creating an Unreal Engine project you may face errors like:
"fatal error RC1015: cannot open include file 'windows.h' "
"fatal error C1083: Cannot open include file: 'new': No such file or directory".
To fix it open your project (not EU4 project) properties/VC++ Directories.
If you see empty fileds like "Include Directories", "Library Directories" then click on the combo box on the right side and choose "inherit from parent or project defaults".
Then compile the project again.

Updated problem #3
I've narrowed the problem. It seems that simply including <thread> makes the compiler go mad.
I am not even making any thread calls, just including it.
I have tried enabling /EHsc and also disabling it.
Disabled, I get:
I get these 6 messages:

And if enabled (Configuration Properties -> C/C++ -> Code Generation & in the Command Line)

I did a simple test with a new, blank project, including thread and just compiling. It went fine, no errors.
However in my main project I am using Chromium Embedded Framework v3, which seems to interact strangely with the thread inclusion?
Seems odd that simply including it would make such a mess.
Any ideas?
Update:
By removing the _HAS_EXCEPTIONS=0 flag entirely and rebuilding the project from CMake, I enter a state where the project won't even compile.
Due to this change it throws out a ton of warnings and errors from various files.
Errors such as:
Warning 230 warning C4530: C++ exception handler used, but unwind semantics are not enabled. Specify /EHsc (C:\Users\mads\Desktop\cef_binary_3.2526.1347.gcf20046_windows32\cefclient\browser\client_handler_osr.cc) C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\xlocale 337 1 cefclient
According to a lot of asking around and googling, the solution to this is to specify /EHsc in Project Properties -> C/C++ -> Code Generation -> Enable C++ Exceptions = Yes(/EHsc).
As well as setting the flag /EHsc in the Command Line input field.
However, nothing changes. The same errors come out as if nothing was changed.
Update:
The error
Warning 2 warning C4530: C++ exception handler used, but unwind semantics are not enabled. Specify /EHsc (C:\Users\mads\Desktop\cef_binary_3.2556.1368.g535c4fb_windows32\libcef_dll\transfer_util.cc) C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\xlocale 337 1 libcef_dll_wrapper
comes from the project "libcef_dll_wrapper", despite the fact that I HAVE speficied /EHsc in its project settings! Both in C++ -> Code Generation page and the Command Line
Solution edit:
Turns out that cmake files would override my set settings everytime I attempted to build or run the project, hence rendering any changes I made un-used, despite being set!
I was able to solve the problem by editing the project's cmake files directly.
Never used cmake before, so in the end it became a learning experience.
I have tested my project with thread inclusion now and it compiles as expected!
Thanks to all for great suggestions
Make sure neither the code nor the compiler command line define _HAS_EXCEPTIONS=0.
Compiling VC++ 12.0 with _HAS_EXCEPTIONS=0 and including concrt.h causes a compiler error:
If a source file is compiled with VC++ 12.0 with _HAS_EXCEPTIONS set to 0 and the source includes, whether directly or indirectly, concrt.h, the compiler gives an error of:
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\concrt.h(4774) : error C3861: '__uncaught_exception': identifier not found
[...] Macro _HAS_EXCEPTIONS=0 is undocumented and unsupported by Microsoft.
It may work with some parts of the STL library for legacy reasons, but it won't be compatible with ConcRT library (concrt.h) since ConcRT depends on exceptions for cancellation.
I recently installed the VS2011 beta to get a feel for the new C++11 features Microsoft had implemented in the latest release of their compiler.
I've had an unexpected problem when going back to use VS2010 though. I've opened a Windows SDK 7.1 sample project in VS2010.
Now when I build in VS2010, I get the following output, denoting that a code analysis tool is being executed (seemingly after compilation, but before linking)

I've attempted to determine what change to the project has caused code analysis tool to be executed, but I can't find anything in the project properties. I've tried reloading the project in VS2011, but there's no option for code analysis that I can turn off (as suggested on MSDN).
The project is completely native C++, I've never used C++ with CLR
Further, I've tried opening other projects (my own) and now they're also invoking this code analysis stage. This prevents building due to problems with Microsoft code in many cases! Builds seem to succeed in VS2011 beta.
Can anyone offer insight into how to turn this code analysis tool off? I would hope to leave VS2011 beta installed, so please refrain from suggesting uninstalling it, unless it's the only option!
I think only VS2010 Ultimate supports code analysis. I don't have VS2012 but I think you should edit the vcxproj file manually.
Look for one or both of these params if they exist inside your project file:
<RunCodeAnalysis>true</RunCodeAnalysis> and <EnablePREfast>true</EnablePREfast>
Change both values to false and it should work.
Please note that these names are used by VS2010 and I am unsure if they changed it in VS2012.
