NIOSII - Write output to Dev kit LCD

I am trying to switch over to eCos from MicroC/OS-II. I have succesfully installed eCos for NIOS 5.0. I have built and run the eCos hello example. I am now trying to modify the hello example ...

Dear monkeyboy.

I'm tring to include "altera_avalon_pio.h", as you wrote.

(1) Adding this line to my c-file.# include "altera_avalon_pio.h"

(2) Modifying CFLAG in makefile.

CFLAGS = -I$(INSTALL_DIR)/include -I'$(SOPC_KIT_NIOS2)'/components/altera_avalon_pio/inc -I$(PREFIX)/include/cyg/hal

But when I built the project, this error message appeared. 

make INSTALL_DIR=/cygdrive/c/temp/ecos_install all 
nios2-elf-gcc -c -o hello.o -I/cygdrive/c/temp/ecos_install/include -I'c:/altera/kits/nios2'/components/altera_avalon_pio/inc -I/include/cyg/hal -g -O3 -ffunction-sections -fdata-sections -fno-rtti -fno-exceptions -fvtable-gc -DSYSTEM_BUS_WIDTH=32 -mhw-mul -mhw-mulx -mno-hw-div hello.c
cc1: warning: command line option "-fno-rtti" is valid for C++/ObjC++ but not for C
cc1: warning: command line option "-fvtable-gc" is valid for C++/ObjC++ but not for C
hello.c:3:31: altera_avalon_pio.h: No such file or directory
make: ***  Error 1

What is wrong?

Please tell me why.

Thank you.

Best regards.
