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!
