I have been using Qt Creator for some time now, and it has been doing a great job of allowing me to make all kinds of cool applications. I do have one question, however. If I build a project in release mode, and then switch to debug and simply build again, it doesn't seem to recompile the project. I managed to prove this by having a project that in release mode would build a library file named 'xxx' and for debug it would be called 'xxx_d'. I switched to release, and it compiled fine. I then switched to debug, and hit "build project", and sure enough, the xxx_d file was created. However, it was exactly the same as the xxx file (file sizes were identical, no debugging info). It was not until I hit "rebuild project", under debug, that the debugging information was including and the library was then much larger. Is there an option that I can select to ensure that the projects will be rebuilt after switching cofigurations? The workaround is fine, but I thought maybe I was missing something.
