QtCreator 4.9.1 online installer errors out when launching QtCreator

[gusain]

@jsulm I want to build QtCreator myself but I only see online installer in Downloads section. Am I missing something ? How do I get src tar-kit for QtCreator which I can use to build QtCreator manually ?

Hi,

You can find them all there: https://download.qt.io/official_releases/qtcreator/

@SGaist Thanks !! Let me see if I can fix dependencies and make it work.

I get this error now when trying to build QtCreator, anyone knows what's going wrong?

qbsproject.cpp: In member function 'bool QbsProjectManager::Internal::QbsProject::addFilesToProduct(const QStringList&, qbs::ProductData, qbs::GroupData, QStringList*)':
qbsproject.cpp:278:43: error: 'class qbs::Project' has no member named 'addFiles'
qbs::ErrorInfo err = m_qbsProject.addFiles(productData, groupData, QStringList() << path);
^~~~~~~~
qbsproject.cpp: In member function 'bool QbsProjectManager::Internal::QbsProject::removeFilesFromProduct(const QStringList&, qbs::ProductData, qbs::GroupData, QStringList*)':
qbsproject.cpp:305:32: error: 'class qbs::Project' has no member named 'removeFiles'

What version are you trying to build ?

[mrjj]

Hi
Seems like this
https://bugreports.qt.io/browse/QTCREATORBUG-20360
So fix might be to install qbs and set QBS_INSTALL_DIR.

Restarting build from clean src fixed this issue but QtCreator doesn't work.

qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: linuxfb, minimal, offscreen, vnc, webgl.

Are you starting Qt Creator from the command line ?
With what version of Qt did you build it ?
Start it with the QT_DEBUG_PLUGINS environment variable set to 1. It should give you more information about what is happening.

[gusain]

@SGaist Yes, I started it from command line. Here is what I get when I set

QT_DEBUG_PLUGINS to 1

Did you build that version of Qt yourself ?

[gusain]

@SGaist Yes, I built Qt 5.12 myself.

Then you didn't build the XCB backend. This usually mean that you were missing dependencies at configuration time.
