Re: Need help for LIRC + remote on serial COM port on recent Linux distrib

Hello, I finally managed to get working for the fist two steps : mode2 
and irrecord are OK. There is only one problem left : lircd KO 
/sbin/lircd: symbol lookup error: /sbin/lircd: undefined symbol: 
release_map_remotes

Could someone could help me to fix this problem ?

Thanks a lot !
Karim
