Hello.

Im new in the DSP field. Im doing a FIR filter and I get the following error:

undefined                        first referenced
symbol                              in file
---------                        ----------------
_fir                             C:\ti\myprojects\filtro1\Debug\filtro2.obj
>>   error: symbol referencing errors - ./Debug/filtro1.out not built

Build Complete,
1 Errors, 0 Warnings, 0 Remarks.

What is missing in my code?? Im using the fir function from dsplib, I have the header in my code.

You need to add the path to the dsplib to the linker include options.

In addition, you need to add the library file to the project for the linker. A header file allows the C compiler to know the prototype defintion for the fir filter routine, but you still need to have the linker find it and resolve this address, pull it into the image, etc.
