Re: [directfb-dev] Segmentation fault on running DirectFB-1.4.1

Tue, 29 Sep 2009 02:19:47 -0700 



Hi Siddharth,
We do have the driver which will complement libdirectfb_fbdev.so, libdirectfb-1.4.so etc..to accelerate. This is provided by the chipset manufacturer. This is working prerfectly with other DirectFB versions. 
Platform is Broadcom.

Are u using DevMem or FBDEV for [SYSTEM] ...i think its fbdev..In this case..for Hardware Mode, you need Driver which will compliment libdirectfb_fbdev.so, libdirectfb-1.4.so etc..to accelerate. Whats your platform.. is it on PC or some Hardware(Like ST, Broadcom etc..)..

Hi Siddharth,
Thanks for your comments. We are getting the same error when we run the DirectFB test application. We have already tried with DirectFB-1.0 and DirectFB-1.1. It is working perfectly in hardware/software modes. Also we need DirectFB-1.4 because of some extra functionalities available in this version.

Ajaz H

Not sure whats the problem, but it seems that you are using GTK_2.0.9 . If thats the case then the first thing to be done is to upgrade to GTK 2.10.1 or greater. Also, you can just try to use DFB Ver 1.0 or 1.1 (It has been working fine with GTK 2.10.1 in Software/Hardware mode), before moving to 1.4.1. Regarding Hardware mode, you need the corresponding DFB Hardware driver for your platform.
