How to Configure for cross compilation?

Hi, I am using QT Creator 2.7 on Ubuntu and want to cross compile/debug on the Beaglebone. I have downloaded and run make on qt-everywhere-opensource-src-4.8.4. I have also downloaded and set up the Angstrom toolchain – that works. My problem is in setting up the kit for the Beaglebone. I always get an error if I select Qt 4.8.4 in the Qt Version box and I get a warning symbol if I select none for the Qt version. What are the correct options here? Thanks! ps. Settings shown below. https://www.dropbox.com/s/m4u8bu4pwxx50lh/Clipboard01.jpg https://www.dropbox.com/s/2hz6n2uln0zv1cz/Clipboard02.jpg
