hi,all
In dmai_2_10_00_12, Sound_alsa.c call the alsa API, it include the head file like this " #include <alsa/asoundlib.h> " , There is no ploblem while I compile it. I want to write a program to record and play audio use alsa API directly, that is I could not use Sound_read() Sound_write(). In my program I include asoundlib.h , and my program is locate in dvsdk_demos_3_10_00_16/dm365/alsa_info/
When I run make to compile it , it occur some errors like following.
Making all in subdirectory alsa_info...
Compiling alsa_info.o from alsa_info.c..
alsa_info.c:7:28: error: alsa/asoundlib.h: No such file or directory

Even I use the absolute path, #include "/home/realtimedsp/dvsdk/linuxlibs-2009.11-armv5te/include/alsa/asoundlib.h" . There is still some errors .
