cqtdeployer Could not load the Qt platform plugin "xcb"
-
Hello, When I try to create an installer with cqtdeployer, I am unable to create a package that is able to run without installing any extra packages.
I did "cqtdeployer -bin camera -qmake /home/username/Qt/5.15.0/gcc_64/bin/qmake qif"
When trying to run on a computer that does not have any qt packages installed I get an error of:
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/username/Downloads/tets/camera/plugins/platforms:" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.
Aborted (core dumped)
If i installed: sudo apt-get install libxcb-xinerama0 than my program will run without any errors.
My question is how do I create the package with the "xcb" plugin included already so I wouldnt have to install it on another computer when running the executable. -

This has been asked before, and is problematic.To satisfy your requirement you would have to do something about packaging whatever gets fetched by
sudo apt-get install libxcb-xinerama0. And that varies by, say, OS distro, plus anything you did package would get out of date over time/upgrade of existing OS. So how do you propose to bundle an always-valid-and-up-to-datelibxcb-xinerama0with your app? -
@JonB Yes exactly, and I am not sure how I would do it exactly that is why I made the post and see if anyone knew a way that had been done.
@rtvideo
I don't see how it can be done, cross-platform and kept up-to-date.The "correct"/best way is to run e.g.
sudo apt-get install libxcb-xinerama0on the target system, if necessary.Perhaps you should consider who your targets are and what is required to satisfy them.
I will leave to others now to comment otherwise.

As @JonB said: this is hardly doable as Linux distributions are too different. What you could do is to provide something like https://flatpak.org/ of your application to include all dependencies of your app in one package.

Hello
This is a bug in the cqtdeployer tool. Fixed now.
Just update your cqtdeployer to version 1.4.7
