I'm trying to build a sound card driver for my project, but when I build the driver the build process fails with the error:
/home/user/Drivers/MircoGrabber/Linux/audio/grabber-audio.c:96:9: error: implicit declaration of function 'snd_pcm_substream_sgbuf' [-Werror=implicit-function-declaration]
I have found that snd_pcm_substream_sgbuf is located in \linux3.0.35\include\sound\pcm.h
There is above a define:
My question is: where in the kernel build menu do I enable CONFIG_SND_DMA_SGBUF? I'm assuming that some where there is another dependancy that I've not yet found?
I'm using the SabreSD board.
