:-1: error: Qt Creator needs a compiler set up to build.
I realized this has been asked a lot just by searching, but I didn't find the exact thing I was looking for.
I am new to QT and tried to compile a test program and received the error ":-1: error: Qt Creator needs a compiler set up to build. Configure a compiler in the kit options."
I installed QT version 5.1.1 32 bit version on windows 7 64 bit version.
When I check the build and run section the only kit without a red exclamation mark is "Desktop Qt 5.1.1 MinGW 32bit (default)" and my compiler is "MinGW 4.8 32bit". From what I've searched I assume they don't work together and I need either a new compiler or new kit but I don't know where to start.
If you download the Qt 5.1.1 for Windows 32-bit (MinGW 4.8, OpenGL, 666 MB) package at http://qt-project.org/downloads, it comes with the correct compiler + library combo that is known to work together. It works on my 64-bit Windows 8 PC. During installation, make sure you tick the box to install the MinGW compiler.
It is important that you don't have any other version of MinGW in your environment -- uninstall all other versions (or at least remove them from your PATH) before installing this one.
Thanks, I'll go ahead and try that now. Ill edit this post later with my results, success or not.
edit: It worked perfectly! Thanks so much, now to further verse myself in using QT.
