windows env variables about gotch HOT 5 OPEN

@Kur-Ich , @chnykn ,

I now can setup a Windows box for testing. Although the issue you mentioned above related to linking issue, it can be fixed by wiring up with absolute path at lib.go file, the compilation still blocked with unsolved issue __assert_fail.... It turns out: Pytorch has not supported MinGW64 GCC at this time while Golang CGO only support MinGW on Window for GCC. So 2 issues to follow up:

1. Pytorch: pytorch/pytorch#42589
2. GO: golang/go#20982

Temporary solution for Windows users would be using WSL2 and install a Linux distribution. If you like your Windows system and have Visual Code installed on your Windows, the following steps might help:

1. Install WSL2 (https://docs.microsoft.com/en-us/windows/wsl/install)
2. Install Ubuntu on WSL2 (https://www.microsoft.com/en-gb/p/ubuntu-2004-lts/9n6svws3rx71)
3. Setup visual code for accessing WSL2 (https://code.visualstudio.com/docs/remote/wsl)
4. Setup Go (install Go on Ubuntu side and set GOPATH environment)
5. Install tools: sudo apt install build-essential clang
6. Setup CC to use clang: export CC = clang export CXX = clang++ to fix undefined reference to mkl... at .bashrc (Ubuntu side)
7. Setup gotch for linux as in README.md file.

Hope that helps.

@Kur-Ich ,

We haven't got a setup instruction for Windows yet!

There's different libtorch for Windows. You can download from Pytorch site:

• Libtorch CPU
• Libtorch CUDA

and unzip to your system. Then setup environment:

• Temporary: in your console/shell window

$Env:GOTCH_LIBTORCH = "PATH_TO_YOUR_INSTALLED_LIBTORCH"
$Env:Path += ";PATH_TO_YOUR_INSTALL_LIBTORCH/lib"

• System-wide: set environment at Control Panel -> System -> Advanced -> Environment Variables

Hope that helps.

Thanks. I've added both but I'm still getting the same error unfortunately. Is anything else needed, such as building the C++ lib with CMake?

I have the same problem on windows

@sugarme thank you, thank you. I've turned to archlinux.
