Dear,
I just installed Archlinux on the Odroid-XU3. But some dependencies were missing to use it directly via a Wifi-module or to use makepkg.
WIFI :
=> wireless_tools
=> wpa_supplicant
=> dialog (To use wifi-menu)
MAKEPKG:
=> base-devel (Some packets were not installed, then the makepkg -si command were not working)
It could be great to add them (at least dialog)
