Hi,

I am having a small issue with subscribing to a topic. I wrote a lot of my
code on an older install of ROS, and I've since decided to install my
package on a 'backup' laptop. Everything compiles and runs fine on the
original, but when I try to compile on the backup laptop I get these errors
about my subscribers:

error: no matching function for call to ‘ros::NodeHandle::subscribe(const
char [15], int, void (&)(std_msgs::Float32))’
/home/ttu/ros/ros/core/roscpp/include/ros/node_handle.h:504: note:
candidates are: ros::Subscriber
ros::NodeHandle::subscribe(ros::SubscribeOptions&)

That error comes from the line of code:
tSubscriber = tHandle.subscribe("TurnAngle", 1, tCallback);

Could someone please help me figure out why this is happening. I have
verified that the syntax is correct, and it compiles fine on an older svn
build of ROS.

I am having the compile problem on a svn build of ROS from today. Also,
there are other executables in the package that have the same subscribe
syntax, but they compile just fine.

Thanks,
Nate
