First, I would like to apologize myself for disturbing you with my problem.
I implemented a lwIP into an existing project running on OS ecos, when i
call the data i receive always invalid conversion from void* to void**! I
call the lwIP with the following code:
static void
httpget(void *arg)
{
int k=1;
int res;
struct netconn *conn;
static char httpreq[255];
struct ip_addr addr;
char *data;
cyg_uint16 len, i;
while(1)
{
sprintf(httpreq,"GET
http://www.ascribo.at/tmobile/showip.php?package=%d HTTP/1.0\r\n\r\n",k);
k++; //incr. ascribocounter
struct netbuf *buf;
// Create a new connection identifier.
conn = netconn_new(NETCONN_TCP);
while (1)
if(lwip_ppp_status() == 1)
{
diag_printf("IP-Address: %u.%u.%u.%u \n",
ip4_addr1(ppp_ip_addr),
ip4_addr2(ppp_ip_addr),
ip4_addr3(ppp_ip_addr),
ip4_addr4(ppp_ip_addr));
}// of if
IP4_ADDR(&addr,213,225,63,42); //www.ascribo.com (funktioniert!)
// Tell connection to remote host.
res=netconn_connect(conn, &addr, 80);
netconn_write(conn, httpreq, sizeof(httpreq), NETCONN_COPY);
diag_printf("%d",conn->type);
while((buf = netconn_recv(conn)) != NULL)
{
do {
netbuf_data(buf,(void*)&data,&len);
for(i = 0; i < len; i++)
{
diag_printf("%c",data[i]);
}
}
} while(netbuf_next(buf) >= 0);
netbuf_delete(buf);
cyg_thread_delay(10);
}
netconn_close(conn);
diag_printf("\r\nDisconnected");
netconn_delete(conn);
diag_printf("Netconn_Delete");
}// of while(1)
}//end of static void httpget(void *arg)
I have at the moment any clue how to solve that problem due to the fact that
i tried any casts already!
Thx for help or any advice!
Robert

You don't say which function call is actually giving you the warnings.
My guess is it is:
> netbuf_data(buf,(void*)&data,&len);
in aph.h we have:
err_t netbuf_data (struct netbuf *buf, void **dataptr, u16_t *len);
your second parameter is wrong. You pass a void *, not a void **.

Hi Andrew, you are right it is netbuf_data , occuring that problem,
I tried already the way netbuf_data(buf,(void**)&data,&len);
I got doing that the linkermessages

This looks like a header file problem:
include/lwip/inet.h:
#if BYTE_ORDER == BIG_ENDIAN
#define htons(x) (x)
#define ntohs(x) (x)
#define htonl(x) (x)
#define ntohl(x) (x)
#else
#ifdef LWIP_PREFIX_BYTEORDER_FUNCS
/* workaround for naming collisions on some platforms */
#define htons lwip_htons
#define ntohs lwip_ntohs
#define htonl lwip_htonl
#define ntohl lwip_ntohl
#endif
Note you are only getting linker errors in your code. The lwip code
itself is happy.
I guess you have not included the correct header file(s).

I got in my maintask following headerfiles included
lwip/sys.h
lwip/api.h
and now
lwip/ inet.h
but my errors are still here!

network.h ???
it is used in the BSD-Stack, isn´t it???
but i am using the lwIP-Stack, i tried already the BSD-Stack, but i have not
enough space

No, it is used in all network stacks.

hi andrew,
i included network.h into my maintask, result ->0 errors are still here,
is there another way to get data from lwIP-Stack ???
i know i sound a little bit desperated already

O.K. so you need to do some proper debugging.
Do you have a big or little endian system?
Does the file which is giving your problems somehow get inet.h
included? What is the value of BYTE_ORDER? What #define htonl is
being included?
To answer these questions you probably want to use the flags -E -dD to
gcc. You might want to look at the gcc documentation to find out what
these do.

Hi!
From firts page of new ST ARM 720 chip we can read:
http://www.st.com/stonline/products/literature/ds/11637/spear-07-nc03.pdf
SPEAR-07-NC03 is supported by several Operation Systems such as eCOS.
Is this port avaliable in public?

I don't remember seeing it anywhere. You probably want to ask ST about
it.
