Mike,
Can you tell me where I can read up on netsend. I have tried to follow your code but I still get a
compile error. I tried this:
#include "u_pdsend.h"
char* host = "localhost";
int port = 8779;
char* protocol = "tcp";
char str[1024];
Then I use pdsend_init(host, port, protocol); then I use it the way you do by:
sprintf(str,"%d (%d,%d)", i, iMeanx, iMeany);
pdsend_message(str);
but I get this compile error:
/usr/bin/ld: Undefined symbols:
pdsend_init(char*, int, char*)
pdsend_message(char*)
collect2: ld returned 1 exit status
Anyway I have been looking for instructions online without success. If you can point the way to a
webpage that would be great.
Alain
