Hi: I have some problem with cross-compiling alsa on the s3c2440; the version of embed system kernel is 2.6.13,and I use alsa 1.0.1.19. I put the alsa driver into the kernel tree. When cross-compiling ,there has error:
"sound/core/pcm.c:25:25: linux/mutex.h: No such file or directory" and I found the kernel 2.6.13 don't have the head file mutex.h but kernel 2.6.22 have the file,. What should I do , I must compile the alsa under the kernel 2.6.22 or older??
