Error when building with fyne get
I'm getting this error when trying to build the app with fyne get on MacOS (Intel, Monterey):

Error building application: exit status 2
Seems like an outdated dependency.
question
I m sorry i m not lawyer, if I want copy this repository, I have to "only" copy your licence or add somethings?
improvements
I sugest these changes:
- add to board nextGenCells:
type board struct {
cells [][]bool
nextGenCells [][]bool
generation int
width, height int
}
- change nextGen() to not copy version :
func (b *board) nextGen() {
b.computeNextGen()
b.generation++
b.nextGenCells, b.cells = b.cells, b.nextGenCells
}
- change computeNextGen() to not create version:
func (b *board) computeNextGen() {
for y := 0; y < b.height; y++ {
for x := 0; x < b.width; x++ {
n := b.countNeighbours(x, y)
if b.cells[y][x] {
b.nextGenCells[y][x] = n == 2 || n == 3
} else {
b.nextGenCells[y][x] = n == 3
}
}
}
}
- maybe change computeNextGen() to concurrent version:
func (b *board) computeNextGen() {
for y := 0; y < b.height; y++ {
for x := 0; x < b.width; x++ {
go func(x,y int) {
n := b.countNeighbours(x, y)
if b.cells[y][x] {
b.nextGenCells[y][x] = n == 2 || n == 3
} else {
b.nextGenCells[y][x] = n == 3
}
b.ch<-true
}(x,y)
}
}
for y := 0; y < b.height; y++ {
for x := 0; x < b.width; x++ {
<-b.ch
}
}
}
- update buildUI() to container.new :
func (g *game) buildUI() fyne.CanvasObject {
var pause *widget.Button
pause = widget.NewButton("Pause", func() {
g.paused = !g.paused
if g.paused {
pause.SetText("Resume")
} else {
pause.SetText("Pause")
}
})
title := container.New(layout.NewGridLayout(2), g.genText, pause)
return container.New(layout.NewBorderLayout(title, nil, nil, nil), title, g)
}
