Ubuntu 16.04: Unknown module(s) in QT: quickcontrols2

diego-qt

Hello,
I am working on a Ubuntu 16.04, using Qt 5.5.1 and QMake version 3.0. I'm trying to compile a project by terminal but I get the error in the title.
As suggested in this question Unknown module(s) in QT: quickcontrols2, I have tried to install the requested package via apt-get but the package doesn't seem to exist

$ sudo apt-get install qtquickcontrols2-5-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package qtquickcontrols2-5-dev

I don't know if the package name has changed but I haven't found a replacement for it yet.

According to e.g. https://forum.snapcraft.io/t/qt-app-with-no-system-libraries-and-without/7638/30

Ubuntu 16.04 don’t have package qtquickcontrols2-5-dev, only qtquick1-5-dev

But I use in my app quickcontrols2. I need this particular package. Ubuntu 16.04 useless to me.

So do you have any evidence that 16.04 supports/comes with quickcontrols2 ?

@JonB I didn't know that 16.04 didn't have this package, I guess my project can't be compiled this way in my computer ?
Should I find another way to install Qt instead ?

It's not installing Qt that is the problem, it is that apparently qtquickcontrols2 is not supplied/was not released at the time of your Ubuntu 16.04. That would mean that, assuming it can be made to work, you would probably have to compile it/Qt yourself. And that is "a lot of work", compared to what you are used to which is just downloading an apt package.

I am not an expert here. You should wait a while to see if someone who knows better than me can suggest if you can obtain it more easily....

@diego-qt Installing manually a newer Qt version could help maybe. But it depends what the highest Qt version is which can be installed on Ubuntu 16.04. Qt Online Installer can be used to install Qt.

I know for a fact that it is possible to have QtQuick.Controls 2 if Qt is built from source
I was looking for a simpler way to install Qt (apt-get) and run a project of my own but if quickcontrols2 doesn't allow it, I'll just have to continue with the online installer option
Thank you both, I'll close the topic if there isn't anything to add
