Can I build DCNV2 on Windows?

[shoutOutYangJie]

I tried it, but failed. Is it possible if I run DCNV2 on windows?

[AndSonder]

I think it is impossible because the project will use .so file.

Yes, it is possible I was just able to build. The process was a pain... I hope I capture it all. I am running Windows 10 and used Visual Studio 2017 to build.

• You want pytorch==1.4 and torchvision==0.5
• From within Visual Studio Installer click modify and install the following.
  • Individual Component > Windows Universal CRT SDK
  • Desktop Development with C++
  • As part of the Desktop Development with C++ you'll need the following optional components
  • Windows 10 SDK
  • VC++ 2017 toolset
• I had to update this line of code https://github.com/CharlesShang/DCNv2/issues/14. You may not have to depending on the version you are on.
• Add the following to your environment vars (your paths may be slightly different so pay special attention here).
  • INCLUDE="C:\Program Files (x86)\Windows Kits\10\Include\10.0.16299.0\ucrt;C:\Program Files (x86)\Windows Kits\10\Include\10.0.16299.0\shared"
  • LIB="C:\Program Files (x86)\Windows Kits\10\Lib\10.0.16299.0\um\x64;C:\Program Files (x86)\Windows Kits\10\Lib\10.0.16299.0\ucrt\x64"
  • Add this to your PATH "C:\Program Files (x86)\Windows Kits\10\bin\10.0.16299.0\x64"

After all of that I was able to get it to build by opening up x64 Native Tools Command Prompt for VS 2017 navigating to the repo, activating my conda environment and running python setup.py build develop

@seth-cohen Now, I got the issue:

corecrt.h”: No such file or directory error: command 'D:\software\VS2017\VC\Tools\MSVC\14.16.27023\bin\HostX86\x64\cl.exe' failed with exit status 2

Do you have any solution?

@ seth-cohen 现在，我得到了问题：

corecrt.h”：没有此类文件或目录 错误：命令“ D：\ software \ VS2017 \ VC \ Tools \ MSVC \ 14.16.27023 \ bin \ HostX86 \ x64 \ cl.exe”失败，退出状态为2

你有什么解决办法吗？

I still have the same question. How can you solve it?
