    undefined reference to `ba2str'

      Hi,

       

      I am trying to run the code below using eclipse but to end up with the above error. Is the bluetooth library supported in eclipse? Please advise.

       

      #include <stdio.h>

      #include <unistd.h>

      #include <sys/socket.h>

      #include <bluetooth/bluetooth.h>

      #include <bluetooth/rfcomm.h>

       

      int main(int argc, char **argv)

      {

          struct sockaddr_rc loc_addr = { 0 }, rem_addr = { 0 };

          char buf[1024] = { 0 };

          int s, client, bytes_read;

          socklen_t opt = sizeof(rem_addr);

       

          // allocate socket

          s = socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);

       

          // bind socket to port 1 of the first available

          // local bluetooth adapter

          loc_addr.rc_family = AF_BLUETOOTH;

          loc_addr.rc_bdaddr = *BDADDR_ANY;

          loc_addr.rc_channel = (uint8_t) 1;

          bind(s, (struct sockaddr *)&loc_addr, sizeof(loc_addr));

       

          // put socket into listening mode

          listen(s, 1);

       

          // accept one connection

          client = accept(s, (struct sockaddr *)&rem_addr, &opt);

       

          ba2str( &rem_addr.rc_bdaddr, buf );

          fprintf(stderr, "accepted connection from %s\n", buf);

          memset(buf, 0, sizeof(buf));

       

          // read data from the client

          bytes_read = read(client, buf, sizeof(buf));

          if( bytes_read > 0 ) {

              printf("received [%s]\n", buf);

          }

       

          // close connection

          close(client);

          close(s);

          return 0;

      }
