Linuxdeployqt error the host system is too new

Hi,

I am trying to build an AppImage for my app which is made using Qt. When I run the AppImage of linuxdeployqt from this site:
https://github.com/probonopd/linuxdeployqt/releases

I get the following error:
«linuxdeployqt (commit deebf70), build 38 built on 2022-12-15 18:06:02 UTC
ERROR: The host system is too new.
Please run on a system with a glibc version no newer than what comes with the oldest
currently still-supported mainstream distribution (Ubuntu Bionic), which is glibc 2.27.
This is so that the resulting bundle will work on most still-supported Linux distributions.
For more information, please see

If this tool does not work what is the other official way to build AppImages for your Qt app?

In my virtual machine do I need Qt and clone the repository and basically do everything I would do on my normal linux boot?

Yes.

Can docker containers work on linux

Of course

@sierdzio How do I run an older version of linux on the current pc which is already booting linux? Can docker containers work on linux or is using a virtual machine better for creating appimage?

Pick whatever you like. For initial setup I’d probably start with a virtual machine because it’s a bit easier to work with a GUI. But if you’re already familiar with this stuff and only need some solution to generate packages — docker is better then. Faster and easier to integrate into CI.

@sierdzio okay I’ve finally managed to setup Ubuntu 18.04(Bionic) on vitual box. When I use the linuxdeployqt tool do I need to compile on virtual machine or just transfer the executable from my pc to the virtual machine?

Compile there, to make sure GLibc compatibility.

@sierdzio In the meantime, I managed to deploy my App on windows that was fairly easy. I used windeployqt tool which was already inside the bin folder of Qt installation.

Now for Linux, I tried using shared folder to share the executable from Ubuntu 22.04(my regular boot) to 18.04(in VM) but when I use linuxdeployqt it does not work. In my virtual machine do I need Qt and clone the repository and basically do everything I would do on my normal linux boot?
