For device type SolarForecast the AI library is not included in v4 image #246

jmpmn-jr commented 2 months ago

Hi, I use V4 minimal image and added a SolarForecast device (76_SolarForecast.pm, https://fhem.de/commandref.html#76_SolarForecast). The AI functionality check complains that Perl module AI::DecisionTree is missing and proposes to install apt library libai-decisiontree-perl. I added the library according to the examples to the docker compose script. I checked that both minimal as well as standard image do not feature this library.

I would like to propose to add the library to the image. I added the library to the docker compose like this FROM ghcr.io/fhem/fhem-minimal-docker:4-bullseye RUN <<EOF LC_ALL=C DEBIAN_FRONTEND=noninteractive apt-get update LC_ALL=C DEBIAN_FRONTEND=noninteractive apt-get install -qqy --no-install-recommends libai-decisiontree-perl LC_ALL=C apt-get autoremove -qqy && LC_ALL=C apt-get clean EOF

If the library is left out by intention, it would be nice to know the motivation. Thank you very much for the effort spent.

I think this is a Bug. I have to check this

jmpmn-jr commented 2 months ago

If I can assist pls let me know. It seems my workaround did not work also. I checked the build outputs, seemed OK. In the container, apt list | grep libai-decisiontree-perl shows it. But the device inside fhem still complains that the library is not found. Maybe it's worth to mention that it's not a fresh fhem, already used in the older container. Cheers

Perl packages which are used by fhem needs to be installed from cpan via CPM or cpanm.

I think i found the bug

sidey79 commented 2 months ago

I added an fix and this will be implemented in the next release tag.

In the meantime it would be nice if you verify, if AI::Decisiontree works as expexted:

ghcr.io/fhem/fhem-minimal-docker:dev-bullseye

Hi, recreated container today with dev tag. Everything seems to work fine. AI support is present. I will use it further to check if there are other effects. Thanks again!
