Hello,

I successfully managed to cross-compile Qt and run my Qt apps on Beaglebone.
Here is my configure:
./configure -prefix ~/armhf-build -opensource -confirm-license -embedded arm -platform qws/linux-x86-g++ -xplatform qws/linux-omap3-g++ -little-endian -host-little-endian -no-webkit

Here is mkspec:
Qt Code: 
  1. #
  2. # qmake configuration for linux-g++
