QtCharts module not found even after installing in Qt Maintenance

[silverfox]

Despite my attempts at installing QtCharts, this module just won't be imported.

From these two questions:

• https://stackoverflow.com/questions/41625233/how-to-include-the-qtcharts-library-in-qt-creator-4-2-0-community
• https://forum.qt.io/topic/85368/how-to-inclide-include-qtcharts-library-to-qt-project

And the docs : https://doc.qt.io/qt-5/qtcharts-index.html

I've already included QtCharts when using Qt Maintenance (I even re-checked it three times):

And restarted QtCreator twice, but it still showed the same error:

What I'm I doing wrong here? Should I reinstall Qt and start with a fresh copy to see if the error reappear?

You can add a custom step to call "jom install".

Hi,

Isn't that a source install and you should build/install it before you can use it ?

Which version of Qt are you using ?

For the first question, umm, if you mean if I've installed Qt, then yes, I have (otherwise I don't understand this question).
Second question, I'm using QtCreator 4.14.2 and Qt 5.15.2 (MSVC 2019, 64 bit).

[SGaist]

I meant the Qt charts module. From the looks of it, you get the sources of it. So you have to first build and install it before using it.

@SGaist
Oh really? How do I install and build it? I didn't know that, I only knew that I have to add it with Qt Maintenance first 😅

[SGaist]

You can open the .pro file in Qt Creator to build it with the Qt version(s) you want to use.

You can add a custom step to call "jom install".

@SGaist
How do I call it and where do I insert it? I found no tutorial that told me I need to install it first.

[SGaist]

I the Qt Creator documentation.

[silverfox]

@SGaist

Could you specify what command to insert and where to insert it?

I have the same problem.
Suspiciously, installation of QtCharts module takes zero bytes!

Here's the output from console usage of maintenace tool.

After many-many times of reinstalling the module nothing changed.
Search finds no files or folders in QT directory, containing "*charts".
Something is definitely broken in maintenance tool.
Trying to install another module, e.g. DataVisualization gives the same result.

@SGaist said in QtCharts module not found even after installing in Qt Maintenance:

Should be located in your sources folder.

@artwaw
Do you mean I have to manually clone it fromn the repo and build it myself?
Why then is it listed as installable module in maintenace tool?
Why 99% of the answers on SO recommend installing it via Maintenace tool then? See topicstarter's SO post and links therein.
This is misguiding.

[artwaw]

@deadundead You already have source installed via maintenance tool. I presume you just need to open the project .pro file, build, install/deploy/copy to Qt bin folders.

[arunkumaraqm]

Somebody please post clear instructions. I just started working with QT a few days ago.
I am on Ubuntu 20.04 and I installed QtCreator with the offline installer. I tried using the maintenance tool to install charts but it still says "module not found".

[deadundead]

@arunkumaraqm I'm on Windows, but i was able:

1. To build charts from the official repo.
2. After I have finally tortured my OS to death and did a clean reinstall of windows and everything, I managed to install charts correctly. The thing is, there are 2 places you can install QtCharts from. The first way is from "additional libraries", which is supposed to be the source install, I think. However I was unable to locate the sources on my PC and got them from the repo.
   The second one is the binary install from Qt->Your version of QT section. And that had just simply worked.
   That was the answer I was trying to push for, cus on SO you clearly see "just install via Maintenace tool", without any mentions of building it from source.
