Installing latest Qt creator on Ubuntu 16.04
-
I have installed Qt creator through online installer on updated Ubuntu 16.04.
Unfortunately Qt creator does not start and response with:
Probably there is already an incompatibility with the different drivers.
Anyone aware how to circumvent the issue?
Certainly an older Qt creator version will help. Which is the latest version supporting Ubuntu 16.04?
Actually I have to compile for Ubuntu 16.04 and hope to use Qt libs version Qt 5.15.2. The application does not require gui output. Simple console and file output is enough. The main thing requried are the Tcp socket stuff and regular expressions I would assume at the moment.
Do I have a chance there?

Hi,
Start Qt Creator with the QT_DEBUG_PLUGINS environment variable set to 1 to see why the plugins does not load.
You are likely missing a system library that is now used by Qt rather than in tree provided.

Cannot load library /home/inposition/Qt/Tools/QtCreator/lib/Qt/plugins/platforms/libqxcb.so: (libxcb-xinerama.so.0: cannot open shared object file: No such file or directory)It is telling you you need to install
libxcb-xinerama.so.0. This has been asked many times in this forum, I would search this forum forxineramaif you want instructions on what toapt-getas there might be other libraries mentioned as needed in the posts (here's one: https://forum.qt.io/topic/116299/qt-creator-ubuntu-20-04/19) .
