No idea what might have changed in my QT Creator options or project options, but for some reason doing a Build (Ctrl-B) or starting a debugging session (F5) now triggers a complete rebuild of my project, which takes several minutes. I'd like it to build only the changed files (and dependencies) as it has always done before. What did I do wrong? I played with the settings "always build before deploying" and "always deploy before running", but changing these just switches between doing no build at all, or doing a full rebuild. How can I (re)activate a "differential" build ? Thanks!
On Mac OS, the files are located in ~/. config/QtProject and ~/Library/Application Support/QtProject/Qt Creator . On Windows in general, the files are located in %APPDATA%\QtProject and %LOCALAPPDATA%\QtProject .
You certainly don't have to use QtCreator to write a Qt program. You also don't have to use qmake but you are asking for trouble by not using it. To do anything even remotely interesting in Qt you will inevitably end up subclassing QObject .
If you don't want rebuild project, you can run qmake
from qt-creator menu and start build
.
If you have a good computer, you can write to make
-j
option, your rebuild time reduce about 3-4 times.
