Can I use complex.h with C6000 compiler version 7.3.4?

Hello Michael,
I don't know if you check this anymore or not but I have the same error about including complex.h, I use CCS 5.2.1 for programming TMS320C6713 which is the embedded processor of a DAQ module that I have.

I found a file with that name in this address:
C:\ti\ccsv5\tools\compiler\c6000_7.3.4\include

however even copy and pasting the file into my project folder those not workout, i have tried both
#include <complex.h> and "complex.h"


I would appreciate your help.
Thanks,
Hessam
