gcc compile error. Can't find a .h file

["ying lcs" <yinglcs@xxxxxxxxx>]

Hi,

I am getting this compile error "amrnb/interf_dec.h: No such file or directory":

gcc -l/root/video-dep-bin/include -fomit-frame-pointer -pthread -E -o
/tmp/ffmpeg-conf-8258-13546-20007.o
/tmp/ffmpeg-conf-29642-13546-19261.c
/tmp/ffmpeg-conf-29642-13546-19261.c:1:30: amrnb/interf_dec.h: No such
file or directory
ERROR: libamrnb not found

But I double check that I have the file 'amrnb/interf_dec.h' under
'/root/video-dep-bin/include'

# pwd
/root/video-dep-bin/include/amrnb
[root@REDHAT3 amrnb]# ls -la interf_dec.h
-rw-r--r--  1 root root 1496 Aug 16 09:32 interf_dec.h

Can you please tell me why gcc cant' find it?  I am using gcc 3.4.4 on
red hat EL4.
