[Qt-creator] Linking error when building 4.7.2

[Davide Coppola]

Hi,

I can't manage to build 4.7.2 (after checking out the git tag) because of
the following linking error:

lib/qtcreator/libqbsqtprofilesetup.so: undefined reference to
`QQmlPrivate::qmlregister(QQmlPrivate::RegistrationType, void*)'

I have Qt 5.11.2 installed on my system and everything is fine when I build
master.

Any suggestions?

Hi,
lib/qtcreator/libqbsqtprofilesetup.so: undefined reference to `QQmlPrivate::qmlregister(QQmlPrivate::RegistrationType, void*)’

Did you do a clean build?
Since that symbol is a private Qt symbol, it looks like you possibly changed the Qt build after your last Qt Creator build, and since libqbsqtprofilesetup did not change between 4.7.1 and 4.7.2 it was not rebuilt against the new Qt version.

Br, Eike

I have Qt 5.11.2 installed on my system and everything is fine when I build master.
Any suggestions?

That's https://bugreports.qt.io/browse/QTCREATORBUG-21340. If you are using Qt Creator to build, you need to
uncheck "Enable Qt Quick Compiler" in the qmake build step.

Unchecking "Enable Qt Quick Compiler" did the trick, thanks a lot.

Just out of curiosity, is this going to skip the build of some components
of Qt Creator?

Thanks

No. The Qt Quick compiler is just an optimization method for QML code that Qt Creator presumably (I have not looked at the code) switches on if any QML files are present in the project.
