Trying to setup Qt Creator

najariner

I downloaded a Qt+Creator package. Specifically [qt-windows-opensource-5.2.0-msvc2012-x86_64-offline] by name. I installed it and also had MinGW compiler independently installed. Now I'm getting the following error when building my project.

12:50:30: Running steps for project chip45_α...

Does anyone know what could help?

Hi and welcome to devnet forum

First of all you cannot use a mix of compiler and pre-compiled Qt libs. Different compiler versions are not compatible.

Did you check if this file is available?
Cannot find file: C:\Qt\Qt5.2.0\Tools\QtCreator\bin\myp\myp.pro.

It looks like you are trying to have a project file within the installation part of Qt. This is not a good idea since you mess up the installation with your source.

Probably best is to create somewhere a separate directory for your projects and start from there (e.g. c:\Source).

In creator you can create a new project and give the desired path for the location of your new project. Try to make a simple "Hello world" application first for checking that the setup is ok.

For your error message shown above, this might be caused by an Anti-virus application, which has removed or denies access to the pro file. However, that is just a guess.

Thanks for the reply @koahnig. Sorry, I'm not too experienced with Qt. The .pro file is indeed there. I moved the project outside to another folder in C and the issue presists. The problem seems to be that my installation doesn't recognize a compiler. I get this message when trying to clean the project.

:-1: error: Qt Creator needs a compiler set up to build. Configure a compiler in the kit options.

Hi
You downloaded msvc2012 Qt version so you need to use Visual studio 2012 as compiler.
(installed separately )
If you use any of the MINGW Qt version, the compiler is
included and installing an extra standalone might just generate issues.

Why such old version ? if i may ask ?
There are much newer released:
https://download.qt.io/official_releases/qt/5.10/5.10.1/

Update:
The error "-1: error: Qt Creator needs a compiler" suggest you do not have visual studio installed so
either install Visual studio 2012 or grab a mingw version of Qt so kit works.
The visual studio Qt do not work with mingw.

@mrjj I figured that was my issue. I went through the official channels but it seems to be a 60gig download and my connection isn't the greatest and I don't want to wait the whole day and then some basically. The installer does let me pick which components to download. What do I need for a simple installation? I just need to write a couple of Qt Widget applications.

Hi and welcome to devnet,

If you use the online installer, just select the MinGW build and compiler as @mrjj.

Hi
60 GB ? THen you must selected multiple.
For desktop development with widgets you just need mingw Qt.
