'Signal: Bus Error' when running on MacOS
I've been trying to use this package to integrate with an application written in Wails. However, whenever I try to run it, it throws an error saying signal: bus error. I've tried taking the basic example from the repo, but even that seems to throw the same error. I have a feeling something is wrong with CGO in my case.
My System
MacOS version: Ventura 13.1 Go Version: 20.2 (I've tried 1.19 and 1.17 but same result) CC env in Go: /usr/bin/clang (I tried the default as well but same result) GCCGO env in GO: gccgo
The Code
package main
import (
"fmt"
"time"
"fyne.io/systray"
"fyne.io/systray/example/icon"
)
func main() {
onExit := func() {
now := time.Now()
fmt.Println("Exit at", now.String())
}
systray.Run(onReady, onExit)
}
func addQuitItem() {
mQuit := systray.AddMenuItem("Quit", "Quit the whole app")
mQuit.Enable()
go func() {
<-mQuit.ClickedCh
fmt.Println("Requesting quit")
systray.Quit()
fmt.Println("Finished quitting")
}()
systray.AddSeparator()
}
func onReady() {
systray.SetTemplateIcon(icon.Data, icon.Data)
systray.SetTitle("Awesome App")
systray.SetTooltip("Lantern")
addQuitItem()
// We can manipulate the systray in other goroutines
go func() {
systray.SetTemplateIcon(icon.Data, icon.Data)
systray.SetTitle("Awesome App")
systray.SetTooltip("Pretty awesome棒棒嗒")
mChange := systray.AddMenuItem("Change Me", "Change Me")
mChecked := systray.AddMenuItemCheckbox("Checked", "Check Me", true)
mEnabled := systray.AddMenuItem("Enabled", "Enabled")
// Sets the icon of a menu item. Only available on Mac.
mEnabled.SetTemplateIcon(icon.Data, icon.Data)
systray.AddMenuItem("Ignored", "Ignored")
subMenuTop := systray.AddMenuItem("SubMenuTop", "SubMenu Test (top)")
subMenuMiddle := subMenuTop.AddSubMenuItem("SubMenuMiddle", "SubMenu Test (middle)")
subMenuBottom := subMenuMiddle.AddSubMenuItemCheckbox("SubMenuBottom - Toggle Panic!", "SubMenu Test (bottom) - Hide/Show Panic!", false)
// subMenuMiddle.AddSeparator()
subMenuBottom2 := subMenuMiddle.AddSubMenuItem("SubMenuBottom - Panic!", "SubMenu Test (bottom)")
systray.AddSeparator()
mToggle := systray.AddMenuItem("Toggle", "Toggle some menu items")
shown := true
toggle := func() {
if shown {
subMenuBottom.Check()
subMenuBottom2.Hide()
mEnabled.Hide()
shown = false
} else {
subMenuBottom.Uncheck()
subMenuBottom2.Show()
mEnabled.Show()
shown = true
}
}
mReset := systray.AddMenuItem("Reset", "Reset all items")
for {
select {
case <-mChange.ClickedCh:
mChange.SetTitle("I've Changed")
case <-mChecked.ClickedCh:
if mChecked.Checked() {
mChecked.Uncheck()
mChecked.SetTitle("Unchecked")
} else {
mChecked.Check()
mChecked.SetTitle("Checked")
}
case <-mEnabled.ClickedCh:
mEnabled.SetTitle("Disabled")
mEnabled.Disable()
case <-subMenuBottom2.ClickedCh:
panic("panic button pressed")
case <-subMenuBottom.ClickedCh:
toggle()
case <-mReset.ClickedCh:
systray.ResetMenu()
addQuitItem()
case <-mToggle.ClickedCh:
toggle()
}
}
}()
}
Command
go run .
Expected Behaviour
You should see a new icon on the system tray.
Actual Behaviour
An error is returned: signal: bus error
Any idea why this occurs? I've tried the same program on a Windows 10 machine and it works fine.
Can you please include the full stack trace? Just the error text does not include enough information for debugging purposes.
