Hello, can you help me?
I have some problems in compiling the sctp code
I list what I did below, can you tell me what is wrong with the process?
 
Step 1, I download the sctplib-1.0.8.tar.gz and socketapi-2.2.0.tar.gz form http://www.sctp.de/sctp-download.html
 
Then, I refer the http://www.sctp.be/sctpapplic.htm to install them
 
for the sctplib-1.0.8.tar.gz
$ tar -zxvf sctplib-1.0.8.tar.gz
$ cd sctplib-1.0.8
$ ./configure
$ make
$ sudo makeinstall
 
for the socketapi-2.2.0.tar.gz
$  tar -zxvf socketapi-2.2.0.tar.gz
$ cd socketapi-2.2.0
$ ./configure
$ make
$ sudo make
 
The processes are ok without error.
 
Step2, I written a code "main.c" for testing the environment.
 
#include <sys/socket.h>
#include <netinet/in.h>
#include <ext_socket.h>
#include <sctp.h>
#include <string.h>
 
int main(int argc,char **argv)
{
  int sock_fd,msg_flags;
  char readbuf[1024];
  struct sockaddr_in servaddr,cliaddr;
  struct sctp_sndrcvinfo sri;
  struct sctp_event_subscribe evnts;
  socklen_t len;
  size_t rd_sz;
 
  sock_fd = socket(AF_INET,SOCK_SEQPACKET,IPPROTO_SCTP);
  bzero(&servaddr,sizeof(servaddr));
  servaddr.sin_family = AF_INET;
  servaddr.sin_addr.s_addr = htonl(INADDR_ANY);
  servaddr.sin_port = htons(265);
 
  bind(sock_fd,(struct sockaddr *) &servaddr,sizeof(servaddr));
 
  bzero(&evnts,sizeof(evnts));
  evnts.sctp_data_io_event = 1;
  setsockopt(sock_fd,IPPROTO_SCTP,SCTP_EVENTS,&evnts,sizeof(evnts));
  listen(sock_fd,5);
  for (;;) {
    len = sizeof(struct sockaddr_in);
    rd_sz = sctp_recv(sock_fd,readbuf,sizeof(readbuf),(struct sockaddr *) &cliaddr,&len,&sri,&msg_flags);
 
    sctp_sendmsg(sock_fd,readbuf,rd_sz,(struct sockaddr *) &cliaddr,len,sri.sinfo_ppid,sri.sinfo_flags,sri.sinfo_stream,0,0);
  }
  return 0;
}
 
and I typed the command
$ gcc main.c -I/usr/local/include -L/usr/local/lib -lsctplib
/tmp/ccYJsaya.o: In function `main':
main.c:(.text+0x17f): undefined reference to `sctp_recv'
main.c:(.text+0x21a): undefined reference to `sctp_sendmsg'
collect2: ld returned 1 exit status
 
The code run on ubuntu 7.10 and 8.04
In the 7.10, the gcc version is 4.1.3, and I do not use the command "sudo apt-get install libsctp-dev lksctp-tools" to install the sctp library.
 
Can you teach me what is wrong with my process?
 
Thanks you!!!
