[gst-devel] Problems when using osssink in ARM

what kind if things can triggle this Alignment trap?
And I just realize I have made a big mistake when cross compile.I use the arm-linux-gcc tool, is /usr/include/ the default include path?
If yes, I think all this cross compile include my host include files. How can i change this default include path? and build a correct include directory?
another question, why most of the application can run but just some error like the sound issues comes out?
So after rebuild all these things, I'll let you know it's OK or not.
Many Thanks,

Note that on an ARM, hitting the alignment trap can either means that the kernel fixes it for you or that it does something ARM specific. To check what it does see the ``User Faults'' field in /proc/cpu/alignment, if this contains ``fixup'' the traps are harmless (apart from causing a performance hit), otherwise the result is probably not what ossink expected. > > Feb 6 09:21:33 freescale user.warn kernel: Alignment trap: > > gst-launch-0.10 (877) disable codec.. > > PC=0x402f7588 Instr=0xe584c008 Address=0x15a104a7 FSR 0x801 > > Feb 6 09:21:33 freescale user.warn kernel: disable codec.. > > Setting pipeline to PAUSED ... > > 0:00:11.602708000 880 0x150c0 DEBUG audiosi > > MXC Enable Codec(write) > > nk gstaudiosink.c:562:gst_audio_sink_create_ringbuffer: creating > > ringbuffer > > 0:00:11.605841000 880 0x150c0 DEBUG audiosink > > gstaudiosink.c:564:gst_audio_sink_create_ringbuffer: created > > ringbuffer @0x841f8 > > Feb 6 09:21:45 freescale user.warn kernel: > > Feb 6 09:21:45 freescale user.warn kernel: MXC Enable Codec(write) Sjoerd -- In order to dial out, it is necessary to broaden one's dimension.
