I wrirte an sound record and processing program which is compiled OK on my host with GCC. But when I change the compiler to bfin-linux-uclibc-gcc, I got:
root@ubuntu:# bfin-linux-uclibc-gcc -o record.out main.c beamformer.c preprocess.c My_math.c -lasound -ldl -lm

the alsa/asoundlib.h is not found. In source codes, I included it by: #indclude <alsa/asoundlib.h>".
I want to know what should I modify for bfin-linux-uclibc-gcc compiler?
Any advice will be appreciated.

Libo

do not compile things as root
random 3rd party libs are not included in the toolchain. it is up to you to provide them. please read the documentation:
