Qt Creator cannot create new projects or configure existing ones

[SGaist]

Does it show any yellow or red sign beside the Kit ?

Did you mix the use of online and offline installer ?

[DanGione]

@SGaist No. And I don't believe I mixed the installation process. It started happening on an install of Qt after months of use so I don't think it's an install thing.

[SGaist]

Got any Windows updates in between ?
Anti-virus ? Some of them are pretty trigger happy and can wreak havoc for development tools.

[DanGione]

No. I'm running windows 7 and I have auto-updates turned off (Maybe not the safest...)

[SGaist]

What version of Qt Creator do you have running ?

[DanGione]

I'm currently running Qt 5.10.1

[SGaist]

That you already wrote and it's clear. I'm asking about the Qt Creator version.

[DanGione]

@SGaist I'm on Qt Creator 4.5.1 (community)

[DanGione]

I've been looking into the "Qt Creator has stopped working" problem whenever I close Qt and it seems to be caused by ntdll.dll. Looking into that as it could be related.

[DanGione]

Am I just on my own on this?

@DanGione Did you try to reinstall QtCreator?

[Revolt]

I have the same problem.

I have Qt Creator:

Qt Creator 4.6.1
Based on Qt 5.10.1 (Clang 8.0 (Apple), 64 bit)
Built on May 2 2018 04:20:50
From revision 065e644d92

installed with:

brew cask install qt-creator

on:

macOS High Sierra 10.13.4 (17E199)

Hi,

What exact error are you getting ?

[Revolt]

@SGaist, The same as the original poster's one:

Project ERROR: failed to parse default search paths from compiler output
Error while parsing file path/to/project.pro. Giving up.

Going to Build > Run qmake was failing too. After simply running qmake in the terminal, it started working.

It was not creating the Run configuration at all, even after cleaning git ignored files (like the .pro.user file for example) and configuring a Build configuration.
