Describe the bug

Hello,

Thanks for your great work on the fyne project. Since the sample code on the fyne website (to create one dialog with one button) built into a 30 MB executable I followed the information here: #2393. I tried doing this command as suggested: package build -ldflags "-w -s -H=windowsgui" and it seemed to build, but the executable size didn't change. Is there a way to fix this?

I'm using linux. Thanks for any assistance.

How to reproduce

Just read what I did above, I guess.

Example code

package build -ldflags "-w -s -H=windowsgui"

package main

import (
"fyne.io/fyne/v2/app"
"fyne.io/fyne/v2/container"
"fyne.io/fyne/v2/widget"
)

func main() {
a := app.New()
w := a.NewWindow("Hello")

hello := widget.NewLabel("Hello Fyne!")
w.SetContent(container.NewVBox(
	hello,
	widget.NewButton("Hi!", func() {
		hello.SetText("Welcome :)")
	}),
))

w.ShowAndRun()

}

Additional Information

Sorry, I wasn't sure what you wanted for sample code.

Coming from the fact that you are using Linux, I would guess that the Windows specific linker option -H=windowsgui causes the compiler to abort because it isn't supported on Linux. Are you sure that it actually built a new binary?

FYI using "fyne package -release" will provide an optimised package using the correct flags for the target operating system.

Thanks for the info,

When I tried "fyne package -release" the executable was larger (around 22 MB) than when I tried "fyne package tags -ldflags -w -s" (a little under 15 MB). Removing "H=windowsgui" did the trick, I guess. Thanks again.
