Today I installed Lirc from git master on my Raspberry PI 3. This caused some headaches. As far as getting Lirc to work, sending IR commands works, I managed circumvent some issues. However they are just workarounds since I have no clue how to properly fix it. Maybe someone else does, or if it is not a bug/problem, can tell me what I should have done instead :) My system is a Raspberry PI 3 running Raspbian jessie with all updates installed: --pi@raspberrypi:/usr/local/bin $ lsb_release -a --No LSB modules are available. --Distributor ID: Raspbian --Description: Raspbian GNU/Linux 8.0 (jessie) --Release: 8.0 --Codename: jessie --pi@raspberrypi:/usr/local/bin $ uname -a --Linux raspberrypi 4.4.50-v7+ #970 SMP Mon Feb 20 19:18:29 GMT 2017 armv7l GNU/Linux So I was following: http://www.lirc.org/html/install.html First I installed the mandatory dependencies, and pyyaml. (Also at some point installed some USB libs / header files to get configure to tell me I would get USB support.) Then I cloned the git repo, git clone https://git.code.sf.net/p/lirc/git lirc-git After running ./autogen.sh and ./configure (with --prefix=/usr because I read this somewhere and I never know which prefix I need/want on different systems T_T), then I ran make and ran into the following errors: --In file included from config_file.c:41:0: --../include/media/lirc.h:14:25: fatal error: lirc/config.h: No such file or directory --#include <lirc/config.h> -- ^ --compilation terminated. This I changed in "include/media/lirc.h" to: #include <config.h> There is no lirc directory and only one config.h file I could find. Next retry: --default.c:37:24: fatal error: media/lirc.h: No such file or directory -- #include "media/lirc.h" -- ^ Checking where this was mentioned: --pi@raspberrypi:~/lirc-git $ grep -R '"media/lirc.h' . --grep: warning: ./test/lirc: recursive directory loop --Binary file ./.git/objects/pack/pack-7f5b1466b3dee227a3de2f5b5d745dfdbd5fa38b.pack matches --./plugins/default.c:#include "media/lirc.h" <------------------------------- Changed --grep: ./tools/lirc-setup/config.py: No such file or directory --./tools/irpipe.cpp:#include "media/lirc.h" <------------------------------- Changed --grep: warning: ./lib/lirc: recursive directory loop Changed to: #include "include/media/lirc.h" Then on the next try I got syntax errors on python stuff like "async def" methods. After some Googling I found that this was supported on Python >= 3.5. Didn't really check further if there is something in testing/unstable (I am very new to the PI/Raspbian), but python 3 in Raspbian respository which I had installed is version 3.4. So I followed "http://bohdan-danishevsky.blogspot.nl/2017/01/building-python-360-on-raspberry-pi-3.html" to install Python 3.6 from source (First purged 3.4). Note: do not use the configure option for optimizations which it will mention. This will take forever on the pi (at least hours which is when I aborted it). Note2: read comments on tech blogs (someone mentioned the "issue" in the note above already). Afterwards I also installed pyyaml, I think with just "sudo pip3.6 install pyyaml". On the next try, I got some error which I do not get at all tbh. All I found is that it might have to do something with libraries for different python versions being used or something like that.

(This I found by adding some prints around it) Manually set version in python-pkg/setup.py (commented out original try except part importing lirc.config): #try: # import lirc.config # VERSION = lirc.config.VERSION.replace('-devel','') #except ImportError: # VERSION='0.0.0' VERSION='0.10.0' Now I could actually build and install lirc. (make && sudo make install) Then I couldn't find tools like irsend, so I installed those: --cd tools --sudo make install Now I seem to have a (at least partially) working lirc: --pi@raspberrypi:~ $ /usr/sbin/lircd --version --lircd 0.10.0-devel After some more looking around I saw Systemd unit files which I installed: --cd systemd --sudo make install After that I did some configuration for my Irdroid (I wanted a cheap, ready-made USB IR Transceiver since I'm horrible with hardware/soldering) and changed the output and pidfile location because I got some errors probably because of my prefix or w/e: ------------------------------------------------------------------------------ pi@raspberrypi:~/lirc-git/systemd $ cat /usr/etc/lirc/lirc_options.conf [lines omitted] driver = irtoy device = /dev/ttyACM0 output = /usr/var/run/lirc/lircd pidfile = /usr/var/run/lirc/lircd.pid [lines omitted] ------------------------------------------------------------------------------ And setting up a remote (I used a remote for ARRIS 2952, used by KPN (interactieve tv) in NL) found on: https://gist.github.com/proycon/d8f730bb47ff6d7eaa12 Then I started the service: --service lircd start This actually ran properly (after fixing the config file location I think, when it did not find the config file it gave a segfault o.O). Then I had to sort out some stuff with the paths of the tools like irsend. I had leftover files from different lirc versions which had to be cleaned up. But then finally testing commands like: --irsend SEND_ONCE KPN GUIDE --irsend SEND_ONCE KPN POWER Etc they worked :) So now I can finally control my KPN settopbox, which has no other options for control at all (no CEC, network ... ) PS. In some git commit I found a mention of an "irdroid" driver for Lirc. In current master this does not seem to exist. Were changes made to the irtoy driver to make it work with more hardware / fw versions or something? Or was I just lucky :) |
