    Hi,
    in this case, are you sure your project is setup correctly ? Could you share the pro file ?

      This may be similar problems as I had lately. However, I am on Windows 7 with creator 2.6.
      I have a rather large project based on subdirs with some libs shared by a couple of applications.
      I noted that changing the source with some debug statements and in the debugger there was no influence on what I had changed. As I found out later Qt creator compiled and linked always the release version only for this particular application. I did the whole bucket of things rebuild, clean and build (as separate steps) also at least some partly "Run qmake" until I found out what happened. In my case it was cured by "Run qmake" for the whole subdirs project. Suddenly the debug build was created.
      It sounds a bit weird, but I assume Qt creator somehow looses track when switching between release and debug modes. IMO not really a logical behaviour, but I do not know what is actually happening in qt creator.

      Especially if you have a complex project, try "Run qmake".

        Yes it's very weird.. I am thinking to switch it in windows for better luck. I run linux on virtual machine, does this make any difference ?

          Do not know. I have not used Qt creator lately on a virtual machine.

          at clouca: that is an option. Maybe someone sees an issue.

              Since it's a subfolder project, how do you setup your DESTDIR variables ?

                  Hi
                  I had this problem in old versions of QtCreator. As far as I remember it's a bug, but is was supposed to be solved in latest version, I believe. Do a google search, you will find similar threads some wich are alreay solved.

                      Those are the versions of Qt lib. Qt creator has currently version 2.7. A Qt creator installed with Qt 4.7 is fairly old.
                      How did you install Qt 5? Which exact Qt5 version are you using? Did you replace also the Qt creator at that time?

                                Do you set the DESTDIR in your pro files ? If yes where do they point to ?

                                Otherwise can you post (i.e. pastebin) your pro files ? So we can see if the problem lies with them or if we can eliminate that as a cause.

                                Did you take a look at the build panel to see where things are built ?

                                    As I said before, without seeing anything from your project I can only make guesses.

                                    If you really can't share anything. The only solution I see for you is to start from scratch a new project using the subdir template with only one sub directory that contains a project for a hello world app. Make it build and run and once that is good. Take one by one the pieces of your other project and integrate it in the one building and running until everything works.

                                        As already mentioned, seeing the pro files could be useful
