How do we install a missing module?

Stokestack · wrote on 31 Jan 2019, 22:35

I was following a tutorial that calls for Charts, and got an error on attempting to add it to the .pro file.

I can find no way to install it. The Maintenance Tool apparently isn't it. This is on Mac OS, latest version (Mojave).

Any ideas on this? Thanks!

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 ?

Sure:

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

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 ?

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.
