Hi members,

I'm now configuring CircleCI to build our tools on Windows, and trying to use cl.exe for it because CircleCI's Windows image has Visual Studio out of the box.

However, it didn't work well so far because the command line flags passed to cl.exe doesn't seem to be for cl.exe.

Here's the error I got:

```

# runtime/cgo

Microsoft (R) C/C++ Optimizing Compiler Version 19.29.30133 for x64

cl : Command line error D8021 : invalid numeric argument '/Werror'

make: *** [Makefile:15: build-windows-amd64] Error 2

```

I found a few related CLs to support cl.exe that are still in review:

https://go-review.googlesource.com/c/go/+/133946/

but it seems to be stopped.

Can I ask experts here about the latest status of supporting cl.exe, or any tips?

Thanks!

Makoto

I think you have correctly identified the status: there was some work
to support it, but it was never completed.

Hi Ian,

I see, thanks for your quick response!

I'm going to use gcc by installing mingw through chocolatey instead.
