Qt Creator cannot create new projects or configure existing ones

DanGione · wrote on 27 Feb 2018, 19:56

I have been using Qt Creator for a class for the past few months and recently I found that I cannot configure the .pro files that the teacher sends us. After doing some checking, I found that I also cannot create any new working projects. It spits out the error:

Project ERROR: failed to parse default search paths from compiler output
Error while parsing file C:\Users\ME\Desktop\BagTester\BagTester.pro. Giving up.

I have already uninstalled and reinstalled Qt already and am using MinGW 32bit. I need to be able to use Qt and MinGW for my class.

Thanks,
Dan

Hi and welcome to devnet,

That's a bit short on details:

What version of Qt are you trying to install ?
How are you installing MinGW ?
Are you using the online or the offline installer ?

I am on Qt 5.10.1. I installed MinGW through the install process for Qt (it tells me it has MinGW 5.3.0 32 bit). I used the online installer.

Did you check the Kit in the Preferences to see if there's something off there ?

One thing that's been happening for a while but never really seemed to affect it was that every time I closed Qt it would spit out Qt Creator has stopped working and said that qtcreator.exe with a version of 4.5.10 had crashed. I just now realized that it was a different version of Qt that was somehow crashing despite not being currently installed.

@SGaist If by kit prefences you mean that MinGW is default, then yes. it is default. It's also the only kit installed.

SGaist · 27 Feb 2018, 20:20

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

Did you mix the use of online and offline installer ?

DanGione · S SGaist 27 Feb 2018, 20:14

@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.

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

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

What version of Qt Creator do you have running ?

DanGione · wrote on 27 Feb 2018, 22:14

I'm currently running Qt 5.10.1

SGaist · 27 Feb 2018, 22:22

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

DanGione · S SGaist 27 Feb 2018, 22:16

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

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.

Am I just on my own on this?

@DanGione Did you try to reinstall QtCreator?

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 · S SGaist 1 Jun 2018, 20:29

@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.
