Trying to setup Qt Creator

  • 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...
    12:50:30: Starting: "C:\Qt\Qt5.2.0\5.2.0\msvc2012_64\bin\qmake.exe" C:\Qt\Qt5.2.0\Tools\QtCreator\bin\myp\ -r -spec win32-msvc2012 "CONFIG+=debug" "CONFIG+=declarative_debug" "CONFIG+=qml_debug"
    Cannot find file: C:\Qt\Qt5.2.0\Tools\QtCreator\bin\myp\
    12:50:30: The process "C:\Qt\Qt5.2.0\5.2.0\msvc2012_64\bin\qmake.exe" exited with code 2.

    When executing step 'qmake'
    12:50:30: Elapsed time: 00:00.

    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\

    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.

    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:

    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.

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