Build errors in Qt

[freezeblue]

set it to the root directory of your Qt installation. /bin is not needed.

Thanks for your reply.

I changed that path to root folder.
Still getting the same error.


here is the compile output from Qt Creater

Running build steps for project QtWorld...
Creating gdb macros library...
No valid Qt version set. Set one in Tools/Options
Error while building project QtWorld
When executing build step 'QMake'
Canceled build.

help me to fix this
