problem changing static IP in socket server application

I'm trying to test simple sockect server example in Cyclone III NIOS II eval kit using NIOS IDE 8.0.

I checked this example in my old version 7.2 of Quartus and it worked fine!!!

I tried to change static IP in simple_socket_server.h using

# define IPADDR0 192

# define IPADDR1 168

# define IPADDR2 10

# define IPADDR3 11

and settind *use_dhcp=0

by making those changes my simple socket server application worked in 7.2. but in this 8.0 version the static IP never changes from the adress 0.10.10.11.

I've debugged the code and I think htonl instruction doesn't work properly.

# define IP4_ADDR(ipaddr, a,b,c,d) ipaddr =

htonl(((alt_u32)(a & 0xff) << 24) | ((alt_u32)(b & 0xff) << 16) |

((alt_u32)(c & 0xff) << 8) | (alt_u32)(d & 0xff))

any suggestion??
