No such plugin: 'peakcan'

rzucca

No plugins subfolder is created.

jsulm

@rzucca That explains your problem

rzucca

Some explanations regarding the solution would be also highly appreciated

Surely I'm overseeing something and/or making some mistake. I'd like to find out what.

And above all, how to solve it

jsulm

@rzucca https://doc.qt.io/qt-6/windows-deployment.html explains how plug-in should be deployed. If no plug-ins where deployed with windeployqt then something went wrong.

rzucca

Believe me, I read this page many times, and even understood some of it.

I couldn't understand how to build Qt statically, nor how to use the Q_IMPORT_PLUGIN() Macro

Sorry for the delay in my answer, I'm only allowed to post something every 10 minutes

No need to build Qt statically and also Q_IMPORT_PLUGIN should not be needed.
All you need to do is to deploy needed plugins as shown in "Creating the Application Package" part of the link.

rzucca

Any suggestions about how to do that? Because windeployqt isn't doing it

jsulm

@rzucca You still can create subfolders by yourself and copy plug-ins there.

rzucca

That's great news, thanks!

I just would like to know which plug-ins I need and where to find them

Depends on what app is using, on what platform, ...
Where to find: in your Qt installation.
Apparently you also need peakcan plug-in.

rzucca

Well, I'm using QT 6.4 on Windows 10. I think I just need the peakcan plug-in.

I already tried to copy the PCANBasic.dll to an handmade plugins subfolder, but to no avail. That's evidently not the component I'm looking for. The plug-in I need must be in the Qt folder, I guess, because Qt Creator can find it

I'm not (consciously) using any other external plug-ins or libraries. Am I missing any important piece of information?

rzucca

@jsulm There are three subfolders of Qt called plugin canbus. Their content seems to be identical, and the same that is added by windeployqt to the canbus subdirectory.

I tried to copy their content to a manually created plugin subfolder in the release, but to no avail

I am still stuck: I know that I must add some plugins to the release, but I still don't know what plugins, or where to find them
