In VS2013 Community Edition, I had a Win32 VC++ clr project I've been working on. I'm trying to use the CefSharp library, and so through nuget I've imported it.
Following the steps found here I learned I had to change from Win32 to x64 as my 'Active solution platform' to avoid this:
error : CefSharp.Common does not work correctly on 'Win32' platform. You need to specify platform (x86 / x64).
However when I follow those steps and add x64 to my project through the configuration manager, I get the following compilation errors:
1>------ Build started: Project: PROJECTNAME, Configuration: Release x64 ------
1> Main.cpp
1>C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\system_error(20): error C2869: 'std::errc' : has already been defined to be a namespace

1>C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\system_error(101): fatal error C1903: unable to recover from previous error(s); stopping compilation
I'm not sure what is causing this or how to solve it.

I am getting the following build error while compiling my project. The whole error can be seen below
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\VC\VCTargets\Microsoft.CppCommon.targets(181,5): error MSB4062: The "GetOutOfDateItems" task could not be loaded from the assembly C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\VC\VCTargets\Microsoft.Build.CppTasks.Common.dll. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask
This error happens every time I start building the project(even the basic Visual C++ project on VS2017). Please help !

MS Visual Studio 2017 (2017 build tools)
trying to build:
qt5.10.1 with QtWebEngine
using jom.exe -j4

I found this forum with a slightly active/recent question asking about this same issue here:
Internal compiler error in outdname.c in VS15.7p3 when building Firefox webrtc code
Is there anything I can do from this point to fix this?
Downgrading my version of VS to 2015 allowed me to bypass this compiler error and compile QT successfully.
I recently created a VS2015 solution to continue development on a C++ project I had been working on. Whenever I try to build the project, I get hundreds of errors from standard C library header files such as string.h, stdio.h, etc.
To try to get to the root of the problem, I created a new, very basic, VC++ win32 console application project, wondering if I'd see the same compiler errors. Here is the code (ConsoleApplication1.cpp):
#include <string>
#include <iostream>
int main()
{
std::string s = "some data to print...";
std::cout << "Printing: " << s.c_str() << std::endl;
return 0;
}
When I attempt to compile this, I get 150+ errors, like this:
1>------ Build started: Project: ConsoleApplication1, Configuration: Release Win32 ------
1> stdafx.cpp
1>C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\stdio.h(309): error C2144: syntax error: 'int' should be preceded by ';'

I have tried to 'repair' Microsoft VC++ 2015 Redistributable(x86) via the Windows 'Uninstall or change a program' utility, to no avail. I also tried to repair Visual Studio 2015 as a whole.
I'm on Windows 7.
Anyone have an idea what is going on here? Am I pointed to the wrong include directory or something?
It appears you have (some of) the headers from a previous version of VS installed in your VS2015 folder. The standard headers in VS2015 are stored off in a folder tied to the version of the CRT (something like c:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt). Repairing or reinstalling VS2015 won't fix this.
I think you'll need to uninstall VS2015, completely delete the folder C:\Program Files (x86)\Microsoft Visual Studio 14.0, then reinstall it. This will likely break the other version (VS2013?) that is installed there, so you might want/need to uninstall that version instead, then repair VS2015.
The header that comes with VS2015 does not appear to have the "int _CRTIMP_ALTERNATIVE" listed in some of the error messages at those lines, while the one with VS2013 does.
I am converting a existing c++ project to 64-bit version from 32-bit version. This project builds fine in 32-bit version, after converting to build for x64 platform in Configuration Manager i am getting bellow build error, are there any specific i have to inherit for 64-bit version or am i missing anything.
