在VS2015 Update 3中构建OpenCV 3.2时，xtr1中出现大量错误 [英] Tons of errors in xtr1common when building OpenCV 3.2 in VS2015 Update 3

问题描述

当在Visual Studio 2015 Update 3中使用OpenCV 3.2，目标x64(在3.2版本中没有x86库)构建简单的OpenCV应用程序时，出现以下错误:

When building a simple OpenCV app in Visual Studio 2015 Update 3, with OpenCV 3.2, with target x64 (there are no x86 libs in 3.2 release), I get the following errors:

1>c:\program files (x86)\microsoft visual studio 14.0\vc\include\xtr1common(100): error C2737: 'std::is_same_v': 'constexpr' object must be initialized

以某种方式，我不认为这是OpenCV的问题，所以我想我在构建过程中缺少某些内容或配置有误.任何建议应更改的建议均表示赞赏:)

Somehow I dont believe this is a problem with OpenCV, so I guess I am missing something in the build process or have something misconfigured. Any suggestions what should be changed are appreciated :)

我关注了以下网站 http: //opencv-srf.blogspot.com/2013/05/installing-configuring-opencv-with-vs.html 关于如何配置VS的建议.

I followed the following site http://opencv-srf.blogspot.com/2013/05/installing-configuring-opencv-with-vs.html when it comes to suggestions how to configure VS.

添加源代码，尽管我认为这与构建的配置有关，而不与源代码有关:

Adding source code, though I believe this is something related to configuration of the build, not to the source code:

#include "opencv2/opencv.hpp"

int main()
{
    return 0;
}

如通过 Visual Studio 2015:C ++ REST API(卡萨布兰卡)无法在VS inlcudes/headers中进行编译，并且可以通过从RC重新安装VS2015到完整社区版来解决.我正在使用VS2015 Enterprise Update 3，所以希望不是根本原因...

I get the same errors when adding OpenCV 3.1 through Nuget as described in OpenCV via NuGet packages with Visual Studio 2015, how to configure? . Interesting enough it looks like similar errors where seen in completely different cases - Visual Studio 2015: C++ REST API (Casablanca) failing compilation in VS inlcudes/headers and where solved by reinstalling VS2015 from RC to full community edition. I am using VS2015 Enterprise Update 3 so I hope is not the root cause...

推荐答案

此问题显然是由VS2015问题引起的.至少在我修复了VS2015安装之后(从Windows中的Program and Features，问题消失了)

This problem was apparently caused by issues with VS2015. At least after I did repair of the VS2015 installation (from Program and Features in Windows, the problem is gone)
