How to install Qt 6 on WSL2 (Ubuntu)

[vishnu]

I am developing on visual studio ok windows but I have to cross compile my application for Linux so I used WSL2 . Without qt libs it compiles fine. But the moment I include qt libs in my CMake it fails. How to fix it ? Thanks for the help!

I tried the following help but didn’t work for Qt 6.

Hi,

AFAIK, you should use the online installer to get a pre-built binary distribution.

Same question here too. Just starting to expand project in to Linux & Mac so I cover all 3 platforms. How can I install Qt6, is there apt install Qt6 or something like that ?
I'm totally new to Linux learning commands now... sigh.

@Dariusz hi, same answer: use the online installer.

@SGaist It seems the online installer itself is not able to run on WSL2 (using WSLg). It fails with the following error:

./qt-unified-linux-x64-4.6.0-online.run: error while loading shared libraries: libxcb-glx.so.0: cannot open shared object file: No such file or directory

Sure it can. It ran fine on my WSL2 instance of Ubuntu 20.04.

libxcb-glx.so.0: cannot open shared object file: No such file or directory

This message tells you that a required library is not installed. So the fix is to install it: sudo apt install libxcb-glx0

But after that, you will probably encounter other missing libraries. These should cover what you need to install and use Qt on Ubuntu:

sudo apt install g++ make libglu1-mesa-dev libxcb-xinerama0 libxcb-cursor0
