hi everybody

I am facing a peculiar problem.  When I run the client file while running gazebo nothing happens. I am running Gazebo 0.7. The same program used to work perfectly and I just tried running it after a week or so. This s happening with every program.

If I click on the usercam screen, it finally gives a message stating:


[vaibhav@localhost Helicopter]$ ./uav5 6665 1
-5-101playerc error   : gethostbyname failed with error [Success]
error: gethostbyname failed with error [Success]

6665 is the port that I am passing. -5101 is being printed by me for debugging purposes. These nos. only get printed when I move something in the usercam screen.

So, basically it stops executing at:
It does print the 1 as can be seen above.
printf("1");
if (playerc_client_connect(client) != 0)
{
    fprintf(stderr, "error: %s\n", playerc_error_str());
    return -1;
}


Player is definitely listening on Port 6665.

P.S. I am mailing it on both the lists as I am uncertain wherein the problem lies. I couldn't find it in the mailing list archives.
