Hi all,
     I've added -lbluetooth in the command, and it successes. But when I run the program, the program terminates and doesn't wait for any mobile terminal involving into the program. What is the problem about my program? And need I really link the header files in bluez-libs/include? If so, should I include like this "bluez-libs-2.14/include/xx.h"? But the /usr/include contains the files. So I wish to know why if it is so.
     Here is the syntax of my program.
int main (int argc, char **argv)
{
 ...
 int no_connection;
 ...
 printf("\E[H\E[J");
 printf ("Bluetooth infrared converter\n\n");
 printf ("Doing initializations !\n");
 no_connection=0;
 do_listen(recv_mode);
 ...
 while (1)
 {
  no_connection++;
  printf("Now %d mobile terminal(s) is(are) using this program\n");
  sprintf (command, "at+cscs=i\"8859-1\"\r");
  ret_code = put_command (command, answer, sizeof (answer), 5, 0);
  sprintf (command, "AT*EAM=\"Bt-IrConverter\"\r");
  ret_code = put_command (command, answer, sizeof (answer), 5, 0);
  submenu_selected = 0;
  while (!submenu_selected)
  {
....
   Thanks very much.
