Error: Qt Creator needs a compiler set up to build



  • I have Qt Creator 2.7.0 and Windows 7 64bit.
    I'm trying to compile a Hello World C++ program with it, but it looks like Qt Creator can't find my compiler (I'm using Windows SDK as C++ compiler). Building fails with error: "Qt Creator needs a compiler set up to build. Configure a compiler in the kit options". When I go to Tools / Options / Build & Run / Kits and select kit "Auto-Detected Desktop Qt 5.0.2 MSVC2012 64bit (default)", "Compiler" select box is indeed empty, but it's also greyed out (so I can't select it), although "Compilers" tab has 3 auto-detected compilers from Windows SDK.
    Can anybody help me? I googled some solutions for this problem, but all they don't work... ;_;

    Hi and welcome to devnet,

    Since you selected the MSVC2012 package you have to install Visual Studio 2012. Or change for the MSVC2010 package.



  • Thank you for the reply!
    How can I change the package? I've got Windows SDK v7.0 installed (with Microsoft C++ compiler v.15.00.30729.01), will it be enough?

    The version of Qt you download needs to match the compiler that you use.

If it does, it should work if you download "Qt 5.1.0 for Windows 32-bit (VS 2010...)".Windows SDK 7 comes with the same compiler as MSVC2010.

    Alternatively, if your graphics card supports OpenGL 2.0 or higher, you can download "Qt 5.1.0 for Windows 32-bit (MinGW 4.8, OpenGL, 666 MB)" -- this package comes with the MinGW compiler.
