Hi all,

I am doing a job about implementing a digital filter into ccs by using
the library function named fir. But whenever I use this, the complier
always report that

>>   error: symbol referencing errors - './Debug/tone.out' not built

I am confused at all. Can anybody give me some clues on this problem?

Did you include the h file for the dsp lib?

There should be more information from the compiler, or is that all? It
usually reports what symbols it has problems with. If there is more
info from the compiler, please post that too.
Might be that you have not set up the paths correctly to the /include
and /lib directories for the FIR function?

acctually I did not. But I do not know which head file should I include. It
seems that there is no clues in the help file. And I also tried to find
something useful from internet but failed. Could you give me some
suggestion?

the function I am trying to use the fir().

that's all the information given by the complier. I am using the "tone"
example as a test. this project also includes other files such as

#include "dsk5510.h"
#include "dsk5510_aic23.h"

there is not any problem to link these files. and in actually fact, I don't
know which library should I use to reference the function fir(). the help of
ccs does not mention information about it.

You can find one fir() function in the dsplib.
Here's the path to the include dir.
<path to CCS installation>\C5500\dsplib\include

You'll probably need to include the lib dir as well
<path to CCS installation>\C5500\dsplib

HTH,
Sima

There should be an example folder in the 55x dsplib folder. Check how 
TI uses fir().
