Error while using Legacy code tool for sldemo_lct​_fixpt_sig​nals_scrip​t

I am getting the following error when i use Legacy tool.

I replicated the exmple of "sldemo_lct_fixpt_signals_script"

but i got following error

legacy_code('generate_for_sim', def);

Does the line:

#include "simstruc.h"

show up in sldemo_sfun_times_s16.c?
