I have a created a NIOS II system with Timer. In my C program, I have included "# include "sys/alt_timestamp.h" .
While compiling, I get the error "undefined reference to alt_timestamp". Basically its not able to find "altera_avalon_timer.h" file.
I have attached the NIOS SDK error snapshot. Pl. suggest suitable resolution for this.
Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
