Problem setting up hector_slam (no map), please help

Hello, I have been trying to make hector slam work on my turtlebot with a hokuyo 04lx laser. I am using ROS fuerte, ubuntu 12.04. Steps I followed: 1) Did rosmake to hector_slam package with no errors. 2) I already have a urdf of my turtlebot with laser installed. (I can use gmapping) 3) I did try the hector_turtlebot gazebo tutorials successfully. I launched the files in this order. 1) turtlebot.launch file 2) hokuyo.launch file 3) hector_slam_launch tutorial.launch The mapping_default.launch file is like this: I can see the laser scan and robot model on rviz. But the fixed frame and target from gives error on /map topic. If I change both of them to /odom the laser scans are shown. Also the Map field gives error. I cannot see the map being built. Also on the terminal in the tutorial.launch file I get strange errors like this: SUMMARY ======== PARAMETERS * /hector_geotiff_node/draw_background_checkerboard * /hector_geotiff_node/draw_free_space_grid * /hector_geotiff_node/geotiff_save_period * /hector_geotiff_node/map_file_base_name * /hector_geotiff_node/map_file_path * /hector_mapping/advertise_map_service * /hector_mapping/base_frame * /hector_mapping/laser_z_max_value * /hector_mapping/laser_z_min_value * /hector_mapping/map_frame * /hector_mapping/map_multi_res_levels * /hector_mapping/map_resolution * /hector_mapping/map_size * /hector_mapping/map_start_x * /hector_mapping/map_start_y * /hector_mapping/map_update_angle_thresh * /hector_mapping/map_update_distance_thresh * /hector_mapping/odom_frame * /hector_mapping/pub_map_odom_transform * /hector_mapping/scan_subscriber_queue_size * /hector_mapping/scan_topic * /hector_mapping/tf_map_scanmatch_transform_frame_name * /hector_mapping/update_factor_free * /hector_mapping/update_factor_occupied * /hector_mapping/use_tf_pose_start_estimate * /hector_mapping/use_tf_scan_transformation * /hector_trajectory_server/source_frame_name * /hector_trajectory_server/target_frame_name * /hector_trajectory_server/trajectory_publish_rate * /hector_trajectory_server/trajectory_update_rate * /rosdistro * /rosversion * /use_sim_time NODES / hector_geotiff_node (hector_geotiff/geotiff_node) hector_mapping (hector_mapping/hector_mapping) hector_trajectory_server (hector_trajectory_server/hector_trajectory_server) rviz (rviz/rviz) ROS_MASTER_URI=http://192.168.111.21:11311 core service [/rosout] found process[rviz-1]: started with pid [16501] process[hector_mapping-2]: started with pid [16502] process[hector_trajectory_server-3]: started with pid [16563] HectorSM map lvl 0: cellLength: 0.05 res x:2048 res y: 2048 HectorSM map lvl 1: cellLength: 0.1 res x:1024 res y: 1024 [ INFO] [1385693168.936804322]: HectorSM p_base_frame_: base_link [ INFO] [1385693168.936939784]: HectorSM p_map_frame_: map [ INFO] [1385693168.937028939]: HectorSM p_odom_frame_: odom [ INFO] [1385693168.937128850]: HectorSM p_scan_topic_: hokuyo_scan [ INFO] [1385693168.937212180]: HectorSM p_use_tf_scan_transformation_: true [ INFO] [1385693168.937281717]: HectorSM p_pub_map_odom_transform_: true [ INFO] [1385693168.937360377]: HectorSM p_scan_subscriber_queue_size_: 5 [ INFO] [1385693168.937426493]: HectorSM p_map_pub_period_: 2.000000 [ INFO] [1385693168.937492279]: HectorSM p_update_factor_free_: 0.400000 [ INFO] [1385693168.937555392]: HectorSM p_update_factor_occupied_: 0.900000 [ INFO] [1385693168.937628583]: HectorSM p_map_update_distance_threshold_: 0.400000 [ INFO] [1385693168.937708414]: HectorSM p_map_update_angle_threshold_: 0.060000 [ INFO] [1385693168.937776160]: HectorSM p_laser_z_min_value_: -1.000000 [ INFO] [1385693168.937842333]: HectorSM p_laser_z_max_value_: 1.000000 process[hector_geotiff_node-4]: started with pid [16620] [ INFO] [1385693170.824508362]: No plugins loaded for geotiff node [ INFO] [1385693170.824670229]: Geotiff node started Got bus address: "unix:abstract=/tmp/dbus-2hLnz9fcNf,guid=bb9cbab66e8849381861c23a00000019" Connected to accessibility bus at: "unix:abstract=/tmp/dbus-2hLnz9fcNf,guid=bb9cbab66e8849381861c23a00000019" Registered DEC: true Registered event listener change listener: true QSpiAccessible::accessibleEvent not handled: "8008" obj: QObject(0x0) " invalid interface!"
