@dheerendra
I have posted my pro file again.please have a look.

dheerendra

This looks ok. Do you have the problem still ? Can you create a new project with all default settings in your QtCreator & check everything works ?

Tanuja

@dheerendra
Yes I created a new project but the problem is still coming. Also there was Qt5cored.dll file which was missing. I added that also.
Is this problem because of that?

dheerendra

Ok. I suspect that issue with your installation. One last check b4 u get into further. I'm assuiming that you are working on windows system. Do you see uic.exe executable in bin directory of your installation ?

Tanuja

@dheerendra
Yes it is there

@Tanuja How did you install Qt?

Tanuja

@jsulm
Downloaded the software and installed it.
It was working correctly when I installed it. After some time it started giving me this error.
As far as I know, there is some issue with my Qt5core.dll file

jsulm

@Tanuja What is the issue with Qt5core.dll?
You could try to install the latest Qt version (5.9.1).

Tanuja

@jsulm
Ok will do that

dheerendra

as @jsulm already suggested, you better install the new version and try. My suspect is that you have installed some other software which has old Qt library in path. This must be causing the issue.

Tanuja

@dheerendra
I will try to install the new version and check.

Tanuja

It's done
I installed it again and now its building perfectly

Hi ,
Just yesterday I installed QT 6.3.2. When I started new project in Qt creator, .pro or make file is not generated ...And also getting ui_mainwindow.h not found.

Please suggest on how to create .pro file.
Thank you.

jsulm

@ru10 Qt6 uses CMake instead of QMake (thoufh you still can use QMake), so look for CMakeLists.txt file.
"And also getting ui_mainwindow.h not found" - this file is generated when you build your project, you should not edit it as your changes will disappear next time this file is generated.

@jsulm Thank you.
Yes i do have CmakeLists.txt file.

Have you tried building your project? You will get these messages until you do.....
