Tested on Ubuntu 17.10 and Ubuntu 16.04 LTS. Should work just as well on other distros however I'm not sure which command will install mingw-w64 correctly

**(Note: Has anyone tried this? Hajime Hoshi has not tried yet.)** ### If you wish to cross compile from a Linux system to Windows you can quite easily do so.
You may not have a Windows machine handy. Start by installing sys/windows from the standard library
But thanks to xgo, it is possible to cross-compile games made with Ebiten! `go get golang.org/x/sys/windows`
You will need xgo: Then you'll need the mingw compiler.
* Debian/Ubuntu:
`sudo apt install mingw-w64`
_Note:_ If package cannot be found on ubuntu make sure you've added the multiverse repository
(`sudo add-apt-repository multiverse`)
``` When completed you should be able to cross compile using this:
go get github.com/karalabe/xgo `CGO_ENABLED=1 CXX=x86_64-w64-mingw32-g++ CC=x86_64-w64-mingw32-gcc GOOS=windows GOARCH=amd64 go build file.go`
```
You will also need Docker: Since that's quite a messy command to use each time you want to test your program you might wanna set up a bash alias in your .bashrc or .profile file.
https://www.docker.com/products/overview * `nano ~/.bashrc`
Make sure docker is in your PATH. * add this line
`alias LinuxtoWindows="export CXX=x86_64-w64-mingw32-g++ && export CC=x86_64-w64-mingw32-gcc && CGO_ENABLED=1 && GOOS=windows"`
to the bottom of the file.
Make sure your Ebiten game is in your GOPATH and run this to cross-compile your game to Windows: Now you may simply use `LinuxToWindows && go build file.go` to cross compile
```
xgo --targets=windows/* /path/to/ebiten/game/in/gopath
```
NOTE: make sure you have a couple of GB's space as xgo will download what it needs to cross-compile the game.
