I'm using the eclipse workbench and have installed MinGw and Qt 4.1.1. I have installed the Qt eclipse plug-in and have attempted the AddressBook tutorial. When I try to "clean" I get the message

(Exec error:Launching failed) Error launching builder (mingw32-make -k clean)

When I try to build the project I get a similar messages

(Exec error:Launching failed) C:\Qt\4.1.1\bin\qmake -recursive AddressBook.pro
(Exec error:Launching failed) Error launching builder (mingw32-make -k)

Being a real newbie I probably can't see the forrest for the trees...

Thanks
