Installation on Ubuntu 20.04

@artwaw , @SGaist , @KroMignon , @mrjj , thank you all, sorted now...

artwaw

@SGaist In theory, yes. Downloaded files should always have execution bit missing. But this is ubuntu, you never know if it will behave like a proper Linux should.

Not sure what you mean: it behaves exactly like it should, executable bit is not set for downloaded files.

artwaw

@jsulm I am not questioning that. In this particular case.

Why do you say this? It sounds like Ubuntu bashing?!?

I use Ubuntu and/or Debian since many years, it works as it should.
Most of the time system error occurred when I force something what the system did not allow ;)

So now having installed Qt from that link, Qt Creator itself will not launch. Any suggestions on how to fault find?

@KroMignon Bashing might be a bit of a strong word but I detest *buntu deeply. Having to work with those over the years I become very cautious as it tends to break in the least suitable moments. Maybe for purely desktop use it is ok, I admit to lack of experience in that regard. In every other aspect it is... Full of surprises, let's say. Of course, still better than most other distros.

@SPlatten what exactly happens? Have you tried to run it from the icon, menu, console? Any messages?

jsulm

@SPlatten Try to start it from the terminal and see whether there are any errors.
Also try to start it with "-noload all" parameter to see whether it makes a difference.

@artwaw , @jsulm , dam it, Virtualbox isn't new and still seems buggy as hell, Shared Clipboard & Drag'n'Drop both set to Bidirectional, neither work.

I've opened a terminal and typed in:

sy@sy-VirtualBox:~/.local/share/applications$ ./org.qt-project.qtcreator.desktop: line 1: [Desktop: command not found
./org.qt-project.qtcreator.desktop: line 3: fg: no job control

Obviously from the list above there are prerequisites required that are not present. Is there a guide on how to get up and running? I was following an online guide by Qt, but I didn't think I had to manually go through the huge list of downloads?

Did you install VirtualBox extensions?
I use Ubuntu 20.04 in a VirtualBox VM on Windows7 and Windows10 host and copy/past or shared clipboard just work.

I hope you did not install Qt as administrator on your Ubuntu VM?

t as administrat

It could be the macOS variant of Oracle VirtualBox. The user I'm using on Ubuntu is a standard user not super user.

Sorry, I never used macOS, can not really help you :(

SPlatten

@KroMignon, apart from the GUI, its Linux.

I have done nothing special:

download the installer from Qt (was an older one 3.1.1)
set execution bit: chmod a+x qt-unified-linux-x64-3.1.1-online.run
launch installer: ./qt-unified-linux-x64-3.1.1-online.run
install required packages: sudo apt-get install build-essential libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386

that's it

SPlatten

@KroMignon , perhaps its an issue with the version of Qt I'm trying to use?

Maybe, I don't know, you could try to download an older one here => https://download.qt.io/archive/online_installers/3.2/

I haven't done any of this download stuff, just looking at your output.

I don't know why you think this is to do with missing prerequisites. It looks like that is being executed as a shell script file where something is wrong? Is it really supposed to be executable??

Hi
I had some issues with creator and newest ubuntu
and had to do
sudo apt-get install libxcb-randr0-dev libxcb-xtest0-dev libxcb-xinerama0-dev libxcb-shape0-dev libxcb-xkb-dev

But the error i got was "Failed to load platform plugin "xcb".

In the Qt install folder in tool/QtCreator there should be a
qtcreator.sh

can you try that one ?

also try the actual binary in that folder and try to run .desktop as not sure it works from shell.

Just tried that and reporting exactly the same.
