So to summarize...
to compile without the IDE you need gbc3 and gba3 and to pass some possibly
vital arguments like -fpublic-control -fpublic-module so application works.
try gbc3 --help gba3 --help to see options.

To Auto-start you just need a .desktop launching icon to reside in
$HOME/.kde/Autostart/ (for kde) or $HOME/.config/autostart/ for others (i
know of)

Auto-start may require a delay to ensure the desktop/toolkits/system
tray/etc have loaded properly before the gambas application starts
I use these settings in the .desktop file...
X-MATE-Autostart-Delay=5
X-GNOME-Autostart-Delay=5

sometimes even the delay didn't work and the application was not able to
detect a system tray before loading so i also added an option to wait for
the tray with this code...

 UseTray = False
 $bHasTray = Desktop.HasSystemTray
  $bWaitForTray = Settings["WaitForTray", False]
  If $bWaitForTray And If Not $bHasTray Then
    For c As Integer = 1 To 60
      Wait 1
      fList.Retries = c
      $bHasTray = Desktop.HasSystemTray
      If $bHasTray Then Break
    Next
    Message("System tray did not load")
  Endif

  If $bHasTray Then UseTray = Settings["UseSysTray", True]

that checks every second for up to 60 seconds if the SysTray has loaded.

Hope that all makes sense :)
