error: `QtValidLicenseForCoreModule' does not name a type

I am getting the following error when trying to compile my code:
error: `QtValidLicenseForCoreModule' does not name a type

I searched on google and 1 of the forums mentions that I must run configure.exe in theQT install folder. I did that but I am still getting the error. Please help

Full output:

What arguments did you run with your configure? If they say you should run configure again, rerun the "Build debug libraries" option from the menu again. That should have all the correct arguments for configure.

thanks. I did that but I got the same error. I then moved all the source code from the .cpp file into the .h file and the error was gone. Its seems like i cannot place any #include in the .cpp file i.e it has to be in the .h file.

NO!!!

You've hacked the problem, not solved it. Put it back and start tracing again. Email me your files if you give up.

Sorry I made so many changes to the file I cannot recreate the problem. When I recreate it I will send it to you.

I was also getting this error at one time. But it spontaneously went away and I'm not sure exactly what I did because I was having other problems around that time. My feeling is that when I created a new project with the old code, that had something to do with solving the problem. I have no explanation as to why that might be so. I also suspect the IDE is quirky at best and buggy at worst.

I can replicate this error by removing the semi-colon before the endif in the header file [the opposite of which solved my other problem].
