Error When executing step "qmake"

John_Thess

Hello programmers

I met something strange in my work.
I have created a database in QT using C++ and SQL.
Everything worked properly, until I updated to QT v6.
I don’t remember the previous version (5…).
When I run the project in 6th version an error appeared repeatedly:

Could not create directory "D:\work\build-D:workTheDataTheData-Desktop_Qt_6_2_2_MinGW_64_bit-Debug"
Error while building/deploying project TheData (kit: Desktop Qt 6.2.2 MinGW 64-bit)
When executing step "qmake"

When I tried to created a new project using 6th version of QT everything worked properly, at least in the first steps (!!!)

The compiler path is “C:\Qt\Tools\mingw900_64\bin\g++.exe”
The default kit is “Desktop Qt 6.2.2 MinGW 64-bit

I think it is not a matter of code, but if you would like to take a glance in my code I will upload it.

Thanks in advance
John

Fix your kits so the yellow and red icons disappear and then use the correct kit to configure your app.

I thank you for your prompt answer. Unfortunately, when I tried some changes using the suggested options, the result was just the same.

For example, in the C++ compiler, the option “MinGQ 9.0.0 64-bit for C++” and the the option "MINGW" lead to no change.

May be I skipped important options during installation.

Thanks anyway

Hi,

Did you install MinGW through the online installer as well ?

John_Thess

Yes, as you wrote.
The installation folder is "C:\MinGW"

John_Thess

What makes me wonder above all is why the compiles works for new projects and does not work for the old one. Truly strange.

Thanks to all.
May be I go back to a previous version.

Unfortunately, dear programmers, nothing works.
Might someone upload images with the right settings for compilers and kits?
I use Qt Creator 6.0.1 Based on Qt 6.2.2 (MSVC 2019, 64 bit)

I upload my current settings

Is it really the path you are getting ?
Did you already try to nuke the .pro.user file in your project directory and configure it again ?

John_Thess

@SGaist The project, I created, is saved in folder named "work" in an external disk (D:\work)
I copy once again the Compile Output.

19:59:42: Running steps for project TheData...

What do you mean by writing "nuke"? Excuse me, but Iam not a professional programmer, neither a native english speaker.
Thank you very much for interesting in my question.

SGaist

Delete the .pro.user file as well as the build directory and reconfigure your project from scratch.

The automatically generated build path is invalid as it contains ":" which if memory serves well is not allowed in file path.

That works. Thank you very much.
Your answer was very helpful and I' ve learned something I didn't Know.

One more question, please.

In my project, a text editor is included. In this editor, I included, among other tools, a button for font editing. A day after, I deleted this button, as well as the function, connected with it and the same function from the header file. I cleaned the project and I rebuilt it.
In the .moc file, the button still seems to be in the project.
What else is to be deleted?

SGaist

Are you using the auto connect feature ?

John_Thess

I use the "go to slot" command from the right click menu.
May be is better to write more code lines?
For example (in an other project of mine):
"QObject::connect(ui->changeIt, SIGNAL(clicked()), this, SLOT(setText()));
//changeIt: the name of a button
// setText: the function I call.

Thanks SGaist...

SGaist

Do you have any slot named like on_<object name>_<signal name> ?

John_Thess

The part of code in the moc file is:
Case 0: t→onSavebtn_clicked(); break;
Case 1: t→newValues_clicked(); break;
Case 2: t→onExitRbtn_clicked(); break;
Case 0: t→onFontbtn_clicked(); break;
//the last button is the one I deleted

John_Thess

I read in a qt tutorial that it is better for programmers to avoid "Go to slot..." command.
Do you agree with this advice?
