I have a application with Qt5.2.1 and I want to add a map using marble.
It is compatible Qt5.3 or Qt5.2.1 with marble or I have to install Qt4.8??

thanks

i think qt4 is more suitable

You can use either version of Qt, depending on your needs.

While many still use Qt 4 (mostly because it still happens to be the default on most distros), Qt 5 is fully supported. I'm doing the Windows builds with Qt 5.3 for example.
