Hi I installed QT5 beta and MINGW on my computer. When I build using the gui, I get ":-1: error: Qt Creator needs a compiler set up to build. Configure a compiler in the kit options." In the option, I can see Desktop QT 5 beta in the kit settings and in the compiler I see MinGw x86 64bits as automatic settings. What is wrong with my configuration ? Should I try a previous revision of Qt ? Can someone help me please ?
