[Development] Cross compile Qt5 for QtCreator -Problem

Fri Jul 25 12:49:05 CEST 2014

Hello Christian & Thiago

First of all thanks for your suggestions.

I know the documentation you cited states to manually cross-build Qt5 to
setup QtCreator, but why don't you just "bitbake meta-toolchain-qt5"?

can you please provide the URL for "bitbake meta-toolchain-qt5"?

I found out
http://wiki.wandboard.org/index.php/Setup_QT_creator_for_developing_QT_apps_on_wandboard
for that, will that work?

sorry, I'm novice to Qt

Thanks
Nilesh kokane
