Could not create SCTP socket

jaypeng

Dear all,

 

I do have an issue regarding SCTP socket. I am using srsLTE to setup test environment. srsEPC is acting as LTE core network and srsENB is acting as LTE access network. Both of two applications need to run on the same Ultrazed board. After I do local compile on a linux box which is Intel CPU supported, it works fine. But when I do cross compile for Ultrazed board which is for ARM platform and run srsEPC, I got error in console - "Could not create SCTP socket".

 

Below is the source code of srsEPC

  m_s1ap_log->info("S1-MME Initializing\n");

  sock_fd = socket(AF_INET, SOCK_SEQPACKET, IPPROTO_SCTP);

  if (sock_fd == -1) {

    m_s1ap_log->console("Could not create SCTP socket\n");

    return -1;

  }

 

I will very appreciate it if any expert can share your experience on how to fix it. Looking forward to your reply.

 

Bests,

Jay

    Hi Jay,

     

    I think this seems like a Linux issue maybe, and not a board issue..

    Anyway, you can print out the error message. It could be that your current Linux image doesn't support SCTP (despite you including the correct header files) since it's not a popular thing.

    I'm just guessing this could be the issue though, I've never used this board. If it turns out from the error message that that is indeed the case then I don't know how you upgrade the image or compile or install sctp (maybe using apt-get or rpm command, I don't know what Linux flavor you're using).

     

    You can print out the error message using:

     

    #include <errno.h>
#include <string.h>
.......
printf("error no. %d - %s\n", errno, strerror(errno));
