Question

I installed QTCreator and Ubuntu SDK as shown here.
When trying to run the code sample provided here, QTCreator tells me it can’t find the Ubuntu.Components QML Module.

Notes:

The build-logs says:

file:///home/giladnaaman/Programming/Projects/CurrencyConverter/CurrencyConverter.qml:2 module "Ubuntu.Components" is not installed

But the directory /opt/qt5/imports/Ubuntu/Components
exists (and is full of files).

After adding importPaths: [ "/opt/qt5/imports" ] to the qmlproject file:

QML module does not contain information about components contained in plugins.

QMetaType::registerType: Binary compatibility break — Type flags for ‘QPaintBufferCacheEntry'[1024] don’t match. Previously registered TypeFlags(0x103), now registering TypeFlags(0x3).

Answer 1

Do not add the importPaths property to the qmlproject.

Did you setup the QML Scene as your QML viewer?

1. In Qt Creator, go to Tools > Options…
2. Choose the External Tools tab, then in the pane select the Preview (qmlviewer) entry
3. On the Executable: field on the right, replace the contents with /opt/qt5/bin/qmlscene.
4. Optionally change the command name by double-clicking on the Preview (qmlviewer) entry from above. You can call it Preview (qmlscene).
5. Click on OK to save the changes.

you’ll be able to view your app through the Tools > External > Qt Quick > Preview (qmlscene)

The Ubuntu SDK is still using the older version of Qt Creator from QT4 it will not be able to locate the Ubuntu Components, and say the components are not found. But the QML Scene used for running the QML GUI will load it and run it without any problems.
