Qt Creator needs a compiler set up to build. Configure a compiler in the kit options

Question

I Have Installed Qt Creator5 with latest binaries. but when i am running any program it is giving me this error.

:-1: error: Qt Creator needs a compiler set

Answer 1

When I installed Qt into folder ~/Qt/ and then manually renamed the folder into something other, I had similar problem. When I restored the folder name into the original ~/Qt/ (specified at the Qt installer), the problem has disappeared; all was solved.
