I can't get WSL build from QT Project?

[HerrWinfried]

I installed a QT plugin with VS 2022, but my goal was to compile on both WSL and windows. I can't get the linux compilation of the project I created on windows. I suspect I have set an incomplete configuration.

[HerrWinfried]

Is the answer to my question so difficult?

Have you actually already configured the deployment to the device?

I suggest you double check the steps shown in

and

Yes, it didn't work. I wish the documents were updated.

I come here from 2023, and document also never update.

Here is my stuck on VS 2022, QT and WSL

Build started...

@Khoi-Vo-Minh said in I can't get WSL build from QT Project?:

The OP's problem would appear to be trying to execute a non binary file (the .out file in the dialog). This was probably a misconfiguration but clearly occurred after an apparently successful build.

Your output gives you command the build system tried to execute to build your project. It failed. Try to run it manually to find out which art failed and you will be closer to solving whatever misconfiguration or missing component you have.

@ChrisW67 Look like this missing config of WSL1 and WSL2 in VS 2022 Tools QT

For WSL1, it's missed textbox for config toolchain path like old document, missing target path, ....

1>C:\Users\khoim\AppData\Local\QtMsBuild\qt_vars.targets(149,5): error : Host command failed.

    <HostExec
      Command="$(Cmd)" RedirectStdOut="props.txt"
      WorkingDirectory="@(WorkDir->'%(HostPath)')"
      Outputs="@(QMakeProps)"
      RemoteTarget="$(ResolvedRemoteTarget)"
      RemoteProjectDir="$(_ResolvedRemoteProjectDir)" />

For WSL2, it try to connect via SSH instead local WSL.
It return with log:

Severity	Code	Description	Project	File	Line	Suppression State

WSL2, I don't want to connect SSH, because it will take down performance build.
