QT Creator not launching in Ubuntu 18.04 Bionic

[aha_1980]

Hi @LostDeveloper

The error message:

"Cannot mix incompatible Qt library (version 0x50905) with this library (version 0x50a01)"

Clearly states, that some library or plugin depends on or is part of Qt 5.10.1.

0x50905 = 5.9.5; 0x50a01 = 5.10.1

Sorry, that's all I can tell for now.

Hi @aha_1980

I guess I found the reason now.
I have a QT5 5.9.5 version in my system but my QT creator is based on QT 5.10.1.

[aha_1980]

@LostDeveloper but then you surely didn't install Creator with apt-get (at least not from official sources).

Where is QtCreator installed? You can try to launch it with the qtcreator.sh shell script.

[LostDeveloper]

@aha_1980 I did install Qt creator with apt-get as what I have mentioned before.

[aha_1980]

@LostDeveloper in that case, it's an Ubuntu problem and we cannot help you :(

[LostDeveloper]

@aha_1980 additional information.. I installed the QT in chroot environment. could it be QT path issues?

@LostDeveloper said in QT Creator not launching in Ubuntu 18.04 Bionic:

I installed the QT in chroot environment

Qt or QtCreator?

[LostDeveloper]

@jsulm Qt5

@LostDeveloper Qt in chroot should not bother QtCreator. QtCreator is installed together with needed Qt libraries. Do you have any other Qt libraries in PATH/LD_LIBRARY_PATH?

[LostDeveloper]

I checked the chroot and found out different version of QT installed.
Chroot environment:
QMake version 3.0
Using Qt version 5.2.1

Top level:
QMake version 3.1
Using Qt version 5.9.5

qtcreator is only installed in top-level.

@LostDeveloper "Cannot mix incompatible Qt library (version 0x50905) with this library (version 0x50a01)".
You have Qt 5.10.1 somewhere - this is the one causing the problem not Qt 5.2.1
