[ros-users] Reserved message names?

[Sanja Popovic]

Hi Josh,

Here is the list of includes:
#include <ros/ros.h>

#include <bookbot/BBox.h>
#include <bookbot/Book.h>
#include <bookbot/BookList.h>
#include <bookbot/Status.h>
#include <bookbot/Table.h>

#include <tf/transform_listener.h>

#include <iostream>

#include <object_manipulation_msgs/GraspableObject.h>

#include <pcl/filters/passthrough.h>
#include <pcl/point_types.h>
#include <pcl_visualization/pcl_visualizer.h>

#include <sensor_msgs/PointCloud.h>
#include <sensor_msgs/PointCloud2.h>
#include <sensor_msgs/point_cloud_conversion.h>

None of the messages I've generated have status as their field.

Anyway, I'll use less generic names in the future.

Thanks,
Sanja

Without more code it's impossible to tell, but likely something you're #including has #defined Status to something you're not expecting.  Nothing in ROS should be doing this.

Hi,

I've created a message for my package named Status and in the code, I had the following function:
void pullPickCallback(bookbot::Status s) {
...
}

When compiling the file, I got the following error:
 /opt/ros/cturtle/stacks/lis/bookbot/src/driver.cpp:57: error: variable or field ‘pullPickCallback’ declared void
 /opt/ros/cturtle/stacks/lis/bookbot/src/driver.cpp:57: error: expected unqualified-id before ‘int’

Line 57 is the one I copied above.

Changing the message name from Status to something else fixed the problem. Is Status reserved name in ROS for something or did I just bump into a really strange bug?

Thanks,
Sanja
