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

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 up to build. Configure a compiler in the kit options.

i have searched the whole internet for answer but its inadequate and not helping. kindly reply the way to get rid of this error.

Solution 1:

i was also having the same problem so what i did is

For linux

sudo apt-get install g++ 
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev

and then closed the qt creator and restarted it and it worked

i do not know which of the above two made it work but it worked !!

For Windows

Below given solution have worked for few people. so it is worth a try.

Delete this file C:\Users\AppData\Roaming\QtProject\qtcreator\toolchains.xml to solve the problem.

Solution 2:

For me on Windows 7 this was solved by clicking on the arrow icon next to the computer icon on the bottom left of the Qt Creator screen above green arrows and then double clicked a compiler on the list and rebuild the project.
