Getting LIRC to work on latest Slackware - what am I doing wrong?
by zenithpbarm from LinuxQuestions.org on (#5DMH0)
Hi
I have a Slackware 13.37 machine I've been using as a media center since 2012. The machine is running LIRC using a serial port receiver (homebrew) connected on COM0 and a generic RC-5 infrared remote. Everything works perfectly.
I have decided to update to Slackware64 current (full install, stock kernel) to get support for ext4 fs. I have then installed latest lirc from source using prefix / to avoid installing in /usr/local.
Lirc installed successfully (make install, no complaints) although none of the postinstall python scripts seem to work.
All of the following attempts are run as root to avoid permission issues during troubleshooting.
Code:bash-5.1# uname -r
5.10.10
bash-5.1# more /etc/slackware-version
Slackware 14.2+Now with the new kernel the old ways of loading lirc_serial module does not work. It seems ir support has moved to the kernel. I therefore proceed to load the serial_ir module :
Code:bash-5.1# setserial /dev/ttyS0 uart none
bash-5.1# modprobe serial_ir
bash-5.1# dmesg
[ 298.689466] serial_ir serial_ir.0: auto-detected active low receiver

Can you help?
