    I've installed the latest Qt version on my Windows 10 machine with the online installer, alongside with the latest MinGW 64 bit versions (in both the Qt section and development section of the installer). I've looked at many posts to try to fix this issue but they do not work for me. I get this error on the example projects I open and ones I create. Here is the log from the compile output:

    01:08:27: Running steps for project addressbook...

    Here are some additional screencaps of my options:

    error2.PNG

    I can confirm that C:\Qt\Tools\mingw730_64\bin\g++.exe exists, and C:\Qt\Tools\mingw730_64\bin is also added to PATH. I've tried the offline installer as well, with and without admin permissions but it didn't work. Everything seemingly looks fine (no red highlights or anything like that) so what is the problem here?

    Same problem here.
    Using Qt 5.14.1, MinGw7.3 64bit
    Had same problem with 5.12.7

    I had exactly the same problem you did. I think the problem is an interaction with Qt and VS2017/VS2019 being installed (or recently upgraded). We were having the same problem building on Windows 10. Our project is compiling our Qt project with both Visual Studio 2019 (using the MSVC compiler), and with Qt 5.12.7 (using a MinGW 64bit compiler).

    We had a pretty big refactor, so I deleted build directories and *pro.user files. Then I had the same thing happen to our Qt projects. I also created a default project, closed Qt and when I restarted it, I could not parse the *.pro file with the same error you saw. After some investigation, I restored .qmake.stash files that I had deleted (from the Recycle Bin) and the build started working again.

    What I pieced out is that Qt depends on qmake running (This bug was supposed to be fixed: https://bugreports.qt.io/browse/QTBUG-60059, but I decided to focus on qmake). After a bunch of trial and error (without a good explanation of why it work), I found a solution.

    I got this procedure to work a few times.

    • delete any build artifacts and *pro.user file
    • open project and configure it for MinGW 64bit.
    • get the error
    • to build->run qmake (You can watch the Compile output to see that it runs properly)
    • click on "File"->Close Project
    • click on "Files"->recent projects and pick your project to open again.
    • Now it's fixed!
    • Be safe and do a build.

    Also, as long as you don't blow away all the build artifacts while QtCreator is closed, opening the project seems to work find. You can blow away all the artifacts while QtCreator is open, and then rebuild before closing and everthing works ok.
