The error I got after doing a 'make base'
My qn.cfg file
ircddb_login='N2NRV'
ircddb0_host='ircv4.openquad.net'
module_b=itap
module_b_device=/dev/ICOM4100
gateway_latitude=42.580390
gateway_longitude=-75.528590
gateway_desc1='N2NRV at home'
link_admin='N2NRV'
dplus_authorize=true
I use my ID-4100 in terminal mode if that makes any difference.
