How do we install a missing module?

Hi,

IIRC, QtCharts is part of Qt 5.12.0.

Are you sure you are building your project with the version of Qt ?

Thanks for your reply. Yes, it's the only version I've ever installed.

Then you already have the module at hand.

What exact problem do you have ?

If I put this in my .pro file:

QT += core gui charts

I get this:

Project ERROR: Unknown module(s) in QT: charts

Can you show your Kit and Qt versions panel in the preferences ?

Stokestack · wrote on 31 Jan 2019, 23:32

Sure:

Good, do you see QtCharts in /Developer/Qt/5.12.0/clang_64/lib/` ?

Stokestack · wrote on 31 Jan 2019, 23:42

Nope. It goes from QtBluetooth to QtConcurrent... no QtCharts in between.

Start the MaintenanceTool application and go in add/remove components. Deploy Qt 5.12.0, you'll see the Qt Charts module as an option there. Just check it, continue and you'll have it.

Unfortunately not. See my original post; there are no individual modules shown in the maintenance tool.

Are you using the online of offline installer ?

If you run the installer in place of the MaintenanceTool do you see Qt Charts as an option ?

Stokestack · 2 Jan 2019, 00:20

Offline, and nope; there are no components shown in the installer.

Correction: It won't let me get that far, because it complains that Qt is already installed in the destination directory.

Just tried the online installer and it behaves the same way.

@Stokestack Using online installer you can install QtCharts but not into your existing Qt installation. You can remove your existing Qt and use online installer instead.

@jsulm Thanks. I had to uninstall the entire thing and re-install.

I used the offline installer again, and it does offer options for the components. So I installed them all, and now Charts is there.

It seems that the maintenance app is defective, since the "add" function doesn't show anything that isn't already installed.

@Stokestack Can be, I don't use offline installer, so can't comment on that

AFAIK, the "add" functionality only works in the Online installer.
