the problem was that i'm using 14.0 Quartus version and example are in 11.1 and the links for the Include files in the Nios project are in "C:/altera/11.1/quartus...", so adding new Include files from "C:/altera/14.0/quartus...". solve the problem
But now when i try to run the project, shows new errors
make: *** [../DE2_115_NIOS_HOST_MOUSE_VGA_bsp/-recurs-make-lib] Error 2 DE2_115_NIOS_HOST_MOUSE_VGA C/C++ Problem
