cross compile source code using alsa on beagleboard

Hi all,
     I have one audio source code from,
and I want to cross compile it and test it on beagleboard.
when I use the following command,
    arm-none-linux-gnueabi-gcc -o playback -lasound playback.c
   it did not find the alsa/alsound.h file, however when I try gcc -o
playback -lasound playback.c, it works fine. I think the main problem
should be include path is not set correct for cross compile.
   how to set the include path for this?

there is not a alsa/alsound.h in your cross compile,you need add it to
your cross compile
