Qt Linux deployment

[PouryaTorabi]

Hi every one,

This is my first time using Linux so I'm having a lot of problems. I have written a qml program and wanted to compile it for linux as some one requested it from me. So as I read in the forum, the best way is to compile in a linux environment, so I installed Qt on an Ubuntu OS and compile my project there, it ran without any problem, I even ran the binary from terminal and it ran perfect, So i tried to move it to another PC to test it, it complained about missing some libraries, I tried to copy the
libraries to /usr/lib, but again it gave an error:

could not find the Qt platform plugin "xcb in "".

So what should I do now, is there better way for deploying qt apps for linux, I read about linuxdeployqt and tried it, it gave me the error:

ERROR: The host system is too new.

Can anyone guide me through this?

Hi,

What version of Qt are you using ?
How did you install Qt ?
On what version of Ubuntu ?
How did you install linuxdeployqt ?

[PouryaTorabi]

@SGaist Qt 5.12.1, Ubuntu 18.04.
I installed the Qt with the installer version for linux and for linuxdeployqt I downloaded the linuxdeployqt-6-x86_64.AppImage and tried to run it from terminal.

What is your target distribution ?

[PouryaTorabi]

@SGaist I just want to run my app in anohter ubuntu 18.04.

[SGaist]

Then why not use your distribution provided Qt ?

@SGaist In windows I would copy the .exe compiled file from debug or release folder and would also copy the required DLLs to the executable folder, so I could easily copy the file and its DLLS to any windows and it would run, In linux I just want to do the same thing, I want to be able to copy my compiled file and its required libraries to another linux and rub it, Just don't know how to do it.

The error message comes with a link to https://github.com/probonopd/linuxdeployqt/issues/340 where you get the full explanation about the message.

It also talks about the -unsupported-allow-new-glibc option.
