What Qt specific files exactly do I need to add when deploying?
-
I am working on creating a tar.gz of my application that will run on every linux distribution. When creating an installer for windows, the qtwin deploy tool moved multiple qml folders and plugins into my deploy folder. What (except the shared libraries) do I need to deploy my application for linux?
@Creaperdown best use some tool for this, like linuxdeployqt, or cmake deplopyment found in newest Qt versions, or other similar tools for flatpak or snap.

@sierdzio thanks. linuxdeployqt says that it only works on the last supported LTS version of ubuntu. Do you have an idea which one that would be?

@Creaperdown let me google that for you
I guess it would mean 14.04.6.

@sierdzio I have tried 14.04 in the past and its too old to do anything on in my experience. Looking through the issues it seems like 20.04 works fine with linuxdeployqt since 18 is near its EOL

I don't know where that might have come from as the "last supported LTS version of ubuntu", since that means 2014, and I doubt Ubuntu stopped there! :) Now it should be 22.04+ (i.e. or later).

Try to add -unsupported-allow-new-glibc parameter to linuxdeployqt call

I am trying linuxdeployqt on 20.04 and it works fine up to the point where I tells me the following:
Does someone have an idea what the issue is?

@Creaperdown The message is clear: libqsqlmimer.so is not installed. Did you install sql module? I have it in my installation.

It is installed. Not installed is its dependency (libmimerapi.so).

@jsulm but it is not listed in
ldd ./myAppand my application works just fine without it. Why do I need it? -

ldd ./myAppand my application works just fine without it. Why do I need it?@Creaperdown Is it possible that you added qt sql module in your pro or CMakeLists.txt file?

ldd ./myAppand my application works just fine without it. Why do I need it?@Creaperdown plugin is different from so although both are libs. Sos are linked to your app and ldd can see all of them. Plugins are loaded from a fixed path at running time and are not exposed to ldd.
it is the harder part to deploy your plugins at the right spot or do not forget to set the path for your app to load them.

@jsulm I cant find an sql module to download from the online installer. Is there a way to fix this? I can not find the libmimerapi.so file in the ubuntu repos either.

@Creaperdown As jsulm said, it could be a bug in the tool since you do not use sql. The tool tries to wrap all plugins.

https://doc.qt.io/qt-6/qtsql-index.html@JoeCFD I have searched through my source directory again and couldn't find any mention of sql, but I found the following:
Could it be possible that this causes the issue?
