Nios II issue

Honored Contributor II



I am using Altera Stratix FPGA ,Quartus 10.1 version and Nichestack IP for TCP/IP communication. 

here in a while loop where i am doing some processing ,i want to measure time . 

for that I am putting alt_timestamp_start()and alt_timestamp( ) functions. 

besides regular header files I am adding "sys/alt_timestamp.h" and "alt_types .h" header files. 

but it is showing error as unrefrenced variable to these functions. 

i want to know which header files i have to add for these functions? 

Thanks in advance.
