How to add mathlib to a 6678 project?

Hi,

I am using TMDSEVM6678le and I try to add mathlib library

in order to use sindp function, here what I did still now:

1) I added mathlib.h header file to my main .c file

2) Included paths in properties->build->C6000 Compiler->Include Options:

       C:\ti\mathlib_c66x_3_0_2_0\packages

       C:\ti\mathlib_c66x_3_0_2_0\inc

3) Included paths in properties->build->C6000 Linker->File Search Path:

       C:\ti\mathlib_c66x_3_0_2_0

Mathlib is intalled in C:\ti\mathlib_c66x_3_0_2_0 folder.

CCS  5.3.0.00090 .

The problem is the result of linking when I compile:

**** Build of configuration Debug for project helloworld_evmc6678l ****

"C:\\ti\\ccsv5\\utils\\bin\\gmake" -k all
'Building target: helloworld_evmc6678l.out'

I hope someone can help me.

Thanks in advance
