LIRC Integration Fails to Load after Failing to Self-Install its Dependencies #71177

Closed kaijk closed 2 years ago

kaijk commented 2 years ago

The problem

I'm attempting to blast IR commands from HA to my IR controlled devices, largely replicating the irsend example shown in the lirc integration page's documentation. irsend is the LIRC component that issues IR commands.

Including lirc: in configuration.yaml causes HA to attempt to install python-lirc==1.2.3.

Note the following from the lirc integration manifest: "requirements": ["python-lirc==1.2.3"]

Python-lirc installation fails and the LIRC integration cannot be loaded.

Please see logs below.

Note: I have lirc 0.10.1 installed in my RasPi Debian Buster environment. It works fine, but irsend is not available to the HA container due to missing lirc libraries that, perhaps, python-lirc used to install. So, HA cannot use a shell_command to directly or indirectly run irsend.

As a test, I docker exec'd into the HA container, symbolically linked irsend and ran it. A number of lirc libraries then report as missing. binding those libraries from the host to the container in my docker-compose file didn't help.

THANKS!

I looked at this a bit more.

  1. I created missing directory /usr/include/lirc/ within the HA container, although maybe this directory would be created by gcc.
  2. gcc itself is missing from HA's alpine OS. I added it with apk add gcc
  3. The python-lirc==1.2.3 installation process then gets a bit further, but fails when it cannot find <limits.h> to #include
  4. I then installed linux-headers (apk add linux-headers) and limits.h is now found at /usr/include/linux. However, that library is still not found during the build
  5. I then installed alpine-sdk by apk add alpine-sdk. This cleared the <limits.h> not found error.

However, now the build fails trying to #include "lirc/lirc_client.h" which is not found.

I don't know how to proceed from there, but I hope this is helpful.

Here's the relevant bit of the log:
