Hi All.
I started writing the following, using the link
http://lwip.wikia.com/wiki/PPP
#############################################################
#include <stdio.h>
#include <unistd.h>
#include "lwip/tcpip.h"
static void tcpip_init_done(void *arg)
{
if (arg) {
*((char *)arg) = 1;
}
}
int main()
{
int setup = 0;
printf("Initializing TCP\n");
tcpip_init(tcpip_init_done, &setup);
printf("Done !!!\n");
while(1)
{
sleep(1);
}
return 0;
}
#############################################################
Following is lwipopts.h ::
#############################################################
#ifndef __LWIPOPTS_H__
#define __LWIPOPTS_H__
#define NO_SYS 1
#endif
#############################################################
Upon compiling, it says that "main.c:18:5: warning: implicit declaration of
function ‘tcpip_init’ [-Wimplicit-function-declaration]", even though
lwip/tcpip.h is very much in the include-path.
Looking at lwip/tcpip.h, it seems that all the function headers are wrapped
within
#if !NO_SYS
So, are there any good starting-points wherein I may implement the
TCP/IP/PPP layers for bare-metal?
Is that even doable for bare-metal?
Thanks and Regards,
Ajay
