copy $prefix/lib/Directfb-1.2.3 directory to board and make sure even board has same $prefix path ... i mean... let say i have cross compiled Directfb on host machine with prefix=/opt/my_directfb then from host machine copy /opt/my_directfb/lib/Directfb-1.2.3 folder to boards /opt/my_directfb/lib directory (you can create this directory if doesent exit in board) I know there must me another solution..
