Btw: Travis now also supports windows (early beta, tho): https://docs.travis-ci.com/user/reference/windows/

That is what actually kicked off this experiment.  The Travis Windows host doesn't come with Cygwin pre-installed and installing it might take 10 minutes

and then I discovered mingw was pre-installed on their Ubuntu Xenial boxes, so I thought it was worth a try. 

 

That's very cool! Would you mind giving the new Windows builds on Travis a go as well? It'd be fantastic if we could bring all CI builds together. I don't know much about mingw compatibility, but I assume it's probably best to build on Windows if possible?

Before trying on Travis I got the the Windows build working locally on my Win10 Windows Subsystem for Linux (Ubuntu Xenial) install. 

Travis report that WSL will be preinstalled... https://travis-ci.community/t/support-for-cygwin-or-wsl/440.

From what I've read recently I don't think building on the Windows side much advantage.  

Under mingw is *still* a cross-compiling when you run it under Cygwin shell, and mingw cross-compiling from a Ubuntu shell is no different.

The only impediment is that mingw-clang is not preinstalled on Travis Linux box, which blocked me from building some of Pharo's third-party libs.

But I'm not sure the impact of that. Subsequently I read that clang was fundamentally designed to cross compile from single binary 

versus gcc producing a separate binary for each cross compiler.  So maybe its just a matter of getting clang's --host & --target flags set right.

There are also some options like wclang to help. (https://github.com/tpoechtrager/wclang)

 

And if we want to run tests, we need a windows machine anyway, whatever the build infrastructure.

AFAIA tests are currently not being run Windows anyway ;)

But anyway, once the vm executable is created, it seems that can be invoked from the WSL side. See "Windows <-> Linux Interop" here...

So yes, I'd be glad dig into Windows boxen on Travis.
