Release builds

[arcticfox1919]

I use the hover build command to generate a Windows executable, but there is a black console, how to publish a real program without a console.

We don't have support for releases yet. For now, hover only builds a debug version of the app with a console to track logs. I'll keep this issue open to track support for release builds.

Things that --release should do:

• Build binary without console (windows: -ldflags -H=windowsgui).
• Building flutter bundle as --release.
• Setting the right VM arguments.
• Reduce the size of the share-lib from 88M to 28M by running strip -s ./libflutter_engine.so.

I am really looking forward to this as well.

Can't wait to play with it.

@GeertJohan Any updates or ETA on this? If not, would you be able to provide any documentation on how to go about removing the console window manually for now? It would be greatly appreciated.

Thanks.

Once my final exams are over, I'll like to take a look at release builds, (if it's not done by then).
For now, #135 provides enough information for you to hack this through.

$ # export CGO_LDFLAGS="-L$HOME/.cache/hover/engine/windows/" # Not working!
$ # set CGO_LDFLAGS="-L%HOMEPATH%/.cache/hover/engine/windows/" # also not working the dll isn't found
$ cd ./desktop/cmd
$ go build -ldflags="-L%HOMEPATH%/.cache/hover/engine/windows/" -H=windowsgui
$ mv cmd ../build/outputs/windows
$ ../build/outputs/windows/cmd # to start the app

@Drakirus Thanks for that. Im assuming its supposed to be set vs export for windows?

[pchampio]

Yup
