amcl needs scan

I run this:
rosrun amcl amcl scan:=scan use_map_topic:=true
But I face this warning:
No laser scan received (and thus no pose updates have been published) for 1388229263.472677 seconds. Verify that data is being published on the /scan topic.
And roswtf output is:
Found 8 error(s).

What's wrong?

What happens when you have your whole system running and then in a separate window run (without quotes): "rostopic echo scan"? I suspect you won't see anything, which either means nothing is publishing to \scan or your environmental variables are configured wrong. What do you have publishing scan?

@tim36272 It publishes data, valid data. I can view it in rviz.

Strange, how about "rostopic info scan"? And is this running on two separate computers over a network or all locally?
Asked by Tim Sweet on 2014-01-06 20:47:59 UTC
Type: sensor_msgs/LaserScan. They are all locally.

When playing from the bag, do you set use_sim_time and --clock? Ie before playing the bag you should run "rosparam set use_sim_time true" and then "rosbag play the_file.bag --clock"

I'll try it
