log_x64_build.log

Hi All

I build OpenCV project failed with error C2665 on Windows + MSVC, this issue is exposed by OpenCV dependency lib Eigen new source code 9aba5274. Could you please help take a look at this? Thanks!

Steps to reproduce:

1.git clone https://github.com/opencv/opencv D:\OpenCV\src

2.git clone https://github.com/opencv/opencv_extra D:\OpenCV\src\extra

3.hg clone https://bitbucket.org/eigen/eigen/ d:\Eigen\src

4.Open a VS 2017 x64 prompt and browse to D:\OpenCV

5.mkdir build_x64 && pushd build_x64

6.cmake -G "Visual Studio 15 2017" -DCMAKE_SYSTEM_VERSION=10.0.17134.0 -DWITH_IPP=ON -DBUILD_SHARED_LIBS=OFF -DBUILD_PERF_TESTS=ON -DBUILD_TESTS=ON -DBUILD_EXAMPLES=ON -DWITH_OPENCL=OFF -DBUILD_DOCS=OFF -DWITH_CUDA=OFF ..\src

7.msbuild /p:Configuration=Release;Platform=x64 build_x64\OpenCV.sln /t:Rebuild /m /p:BuildInParallel=true

The whole log file(log_x64_build.log) please see attachment.

Actual result:
