[BUG]: ImportError: libopenjp2.so (Related to Bookworm or Python3.11 ?)

[naeldavid]

So I have a headless raspberry pi and while scrolling on github, I found Inkycal. For me it was happiness at first sight. Finally something to do with my raspberry pi ! I flashed my micro sd card with a brand new Raspi OS and followed all instructions. While running the code python3 inky_run.py I got this Import error : ImportError: libopenjp2.so.7: cannot open shared object file: No such file or directory

I made sure everything from the requirements.txt file was installed, even started off from scratch twice but I still get the issue. Any Help ?

• OS: Raspberry OS Lite
• Latest Version

Any module I should install ? Or is it a directory/file error and I need to re-install ?

Hi there and welcome to Inkycal. Thanks for opening this issue. As this is your first issue in this repository, please read through the contributing guidelines

@naeldavid Hi there, thanks for informing me about this. Are you sure you ran the following command from the README:

sudo apt-get install git zlib1g libjpeg-dev libatlas-base-dev rustc libopenjp2-7 python-dev-is-python3 scons libssl-dev python3-venv python3-pip git libfreetype6-dev wkhtmltopdf libopenblas-dev

This issue would be new to me as the tests on Raspberry Pi OS are passing. Which OS and version are you using?

Hey @aceisace, I'm sure I ran the command, did it 2 two times to make sure everything works but still get the issue. I have a Raspberry Pi Zero with Bookworm Running :

I re-flashed the micro-sd card and while reconfiguring the Pi and running the command sudo apt-get install git zlib1g libjpeg-dev libatlas-base-dev rustc libopenjp2-7 python-dev-is-python3 scons libssl-dev python3-venv python3-pip git libfreetype6-dev wkhtmltopdf libopenblas-dev I got this :

maybe the issue is linked to this ?

also I restarted from zero running the install and everything and im getting the same error code :

Could it be related to the version i'm using or Python 3.11 ?

[naeldavid]

I also have an idea that could, in my opinion make Inkycal world famous. If we could get in touch to talk about it, it would be great.

I'll try to reproduce this myself on bookworm, though currently I believe that I am using bullseye. However, this will still have to wait at least a few days, as I currently only have access to my own Inkycal. At the moment, this is being used for testing PiSugar integration and stability according to #311 .

I cannot rule out the possibility that it is related to python3.11 , yet, this appears to be a known issue related to dependencies of Pillow and ought to be easy to fix: https://stackoverflow.com/questions/48012582/pillow-libopenjp2-so-7-cannot-open-shared-object-file-no-such-file-or-directo

I'm open to all new suggestions and improvement ideas and there is also a lot of work happening behind the scenes too. You can get in touch with me via Discord on the official Support server

[naeldavid]

While following instruction on the link you sent I got some new errors but I think I know the solution. Anyways, I do not have discord so I cant contact you from there. Basically my idea create a prayer time table and if audio output is connected in my case this and so when it is prayer time eg: Fajr (morning prayer) it would be outputing the Adhan (prayer call). This module could help muslim people far from a mosque be aware of the prayer time at any time by a cool project ! )

What do you think ?

[naeldavid]

Thank You for the email and I think I found the solution : In the Manual Installation documentation you're asking to download python libraries with sudo apt-get install. Install with pip and the person should be good.

I saved it as Ace Github if thats ok with you :)
