    As you can see, i configure for DirectFB but in the summary i have LinuxFB instead.
    I this a bug?

    If i add -no-linuxfb then i get a message saying that my Qt will not have GUI capabilities even though i have directfb.

    Hi,

    Do you also have the DirectFB dev package installed ?



  • Hi Cyrilb,

    Do you fix this issue now ?
    I have same problem as yours.

    Anyone knows how qt to detect DirectFB support or not ?

    Thank You!
