some plugins connot be loaded

amininho

When I installed Qt creator, I faced to this error : "the following plugins have errors and connot be loaded"
and plugins are : "Welcome and QmlDesigner and QmlProfiler plugins"
How can I solve it ?

mrjj

hi and welcome
This is really uncommon error so please state
what version of Qt , how u install it and what platform.

I only seen Welcome fail due to being run in virtual machine.

so you will need to provide all details as you can. :)

@mrjj I installet qt creator by ubuntu software center.
I dont know what is Qt version. but I installed Qt 5 and my Qt creator version is :
"Qt Creator 3.5.1
Based on Qt 5.5.1"
and ubuntu is 16.04

mrjj

ok
it really sounds like a broken install but from the center it sounds so strange.
Maybe there is some mismatch in Qt versions/so files.

Could you try to remove it all and try online installer ?

https://www.qt.io/download-open-source/#section-2

Qt Online Installer for Linux 64-bit (31 MB) (info)
or the full
Qt 5.7.0 for Android (Linux 64-bit, 769 MB) (info)

Normally its best to get from the repos but seems not to work in this case.

mrjj

hi
we could also use
QT_DEBUG_PLUGINS
to list more info on why it dont load the mentioned plugins.

if you set QT_DEBUG_PLUGINS to 1 and export it
then start creator from shell
it should list tons of info.
