TMS320F28335: Which files must be included while using the sgen library

I am trying to use the sgen library for creating a sine wave to be used in sine triangle PWM.

I get the error: 

undefined                 first referenced
symbol                            in file
---------                         ----------------
_SGENT_3_calc     ./mli_1.0.obj

error #10234-D: unresolved symbols remain

Description: unresolved symbol _SGENT_3_calc, first referenced in ./mli_1.0.obj

I did add the includes folder from the library to my project

Is this a linker problem?

Please help, thank you!
