I just update labs to include the examples folder. Please update it first if not.
The graph addon is available on j801, please install it first although I'm not sure if it will work inside iOS which does not support gl2 commands. If you have plenty of bandwidth connect to iX, eg via wifi, I suggest you install all addons to save trouble. eg, load'pacman' 'update'jpkg'' 'install'jpkg'all' Чт, 13 фев 2014, Jim Russell писал(а): > Didn't get very far, looks like my addons are missing some stuff, which might > be my fault.
