Not sure why, but when I compile it.

I get an error, It compiled fine after I just took out the %s & VERSION,
but its odd that it doesn't compile cleanly for me.

$gcc sub_client.c -lmosquitto -o sub_client

sub_client.c: In function ‘print_usage’:

sub_client.c:131:75: error: ‘VERSION’ undeclared (first use in this
function)

  printf("mosquitto_sub version %s running on libmosquitto %d.%d.%d.\n\n",
VERSION, major, minor, revision);

                                                                           ^

sub_client.c:131:75: note: each undeclared identifier is reported only once
for each function it appears in
