Hi,

I'm wondering if anyone knows what these errors mean:

My code is really long to post, so I was wondering if there was something general that these are getting at that I can look out for in my code.

I'm trying to pass std_msgs::Int32MultiArray::ConstPtr& arrays from a subscribed topic into a function to pull out the data.

Any help on this would be greatly appreciated!!

Edit: I am running ROS electric on Ubuntu 11.10.

Please read the support page. At least post the complete error output. You left out the important parts. From what I can see, the problem could be related to a call to subscribe, but without all error messages and the corresponding code it's impossible to say more.

Okay, I have no idea what I was doing, but I changed the lines:

redTrackSUB = mainHUB.subscribe<std_msgs::Int32MultiArray::ConstPtr>("redTrack", 30, &mainProcessing::setCurrPosRED,this);

to

redTrackSUB = mainHUB.subscribe<std_msgs::Int32MultiArray>("redTrack", 30, &mainProcessing::setCurrPosRED,this);

...and it seems to work better now.

If anyone has an explanation, please do so in the comments. Thanks!
