Can't build a project template

i have the same problem too ..

I am building a simple LED test pattern from "Board diagnostics" and selecting my own system (created my SOPC builder in Quartus II).

After that I go to the "system library properties" and change the setting to "program never exits" and "small C library".

when i build them , i got below error message.

Description :

In Fuction 'GetInputString' : board_diag.o

in Function 'main' : board_diag.o

undefined reference to 'getc' : board_diag.c

undefined reference to 'sscanf' : board_diag.c
