Re: [Ltib] DirectFB compilation issue for iMX27ADS board

[Stuart Hughes]

Hi Pascal,

The ltib you have is a bit old and is missing an update to DirectFB
(this is available on Savannah).

Since that BSP we're on version 1.1.0 of DirectFB, you can see the spec
file here:
http://cvs.savannah.gnu.org/viewvc/ltib/dist/lfs-5.1/DirectFB/DirectFB.spec?revision=1.3&root=ltib&view=markup

I'm not sure if you can update to this version with the version of the
BSP you have, but if not I think you may be able to fix your problem by
simply including the DirectFB-1.1.0-linux-config-h.patch in the spec
file you have.  This patch (which will be downloaded for you and is also
here: http://www.bitshrine.org/gpp/DirectFB-1.1.0-linux-config-h.patch )
basically comments out this include.  On later kernels it's no longer
present (and should not be required).

Regards, Stuart
