I get the following error when building a project in Qt Creator:

**error: collect2: ld returned 1 exit status**

Below is the compile output

**Running build steps for project mw_fe...**

Please help me...

Thanks.

cannot find -lQtDBus

The QtDBus module is a Unix-only library. In theory it's possible to compile winDBus and then QtDBus for Windows. But it's not easy and I'm not sure about MinGW...
