Hi, i'm trying to compile on OS is Ubuntu 24.04

i get this error

Can you please tell me what is wrong?

NB, i used cmake .. -DRTLSDR=1

Please see #845

I had the same problem under Ubuntu 24.04, it's related to Qt version.

[AlbrechtL]

The minimal supported Qt version is 6.8. Inside Ubuntu 24.04 the Qt version is too old.

Please follow the section "Debian / Ubuntu Linux" in the README.md (https://github.com/AlbrechtL/welle.io?tab=readme-ov-file#debian--ubuntu-linux) in order to compile welle.io.

I tried this, sort of, but can't run qcreator. I want to build from command-line (inside docker). I only want to use the radio as backend for my snapcast multi-room audio setup. I don't use the frontend, only the built-in webserver using welle-cli.

Thanks to @andimik the last build is running fine without the need to use the QT online installer (and account). I will attach my docker-compose.yaml and Dockerfile in a few minutes. Right now i'm cleaning them up.

For now i modified radio_controller as suggested by @andimik and i copy it over after the git clone. This works fine; maybe i'll later create some sed command to modify it in place.
[edit]in Dockerfile: copy command replaced by sed[/edit]

• Place the below 2 files in a directory
• docker compose build
• wait wait wait ......
• docker compose up -d

NB: last edit ;-) maybe i installed a few packages to much and maybe i can clean up some slack after the installation, but for my use the space is not that much an issue. It works great for now!
