Re: [lwip-users] Problems getting a basic example running

[Fre Net]

I'm using lwip_init() to initialize LWIP. Is this not the correct way to do this? Here's the code from the start of my program to where the error occurs:

int sockfd;

struct sockaddr_in their_addr; // connector's address information

struct hostent *he;

int numbytes;

int broadcast = 1;

lwip_init();

if ((sockfd = socket(AF_INET, SOCK_DGRAM, 0)) < 0) {

 perror("socket?");

 exit(1);

}

Thanks,

Fred

That suggests that it hasn't been initialised.  How are you initialising lwIP in your project?
