I am attempting to convert data from the Pixhawk IMU to a transform broadcast using the "hector_imu_attitude_to_tf" node from the Hector SLAM repository (found at: link text ) However, when I run the file using:

rosrun hector_imu_attitude_to_tf imu_attitude_to_tf_node.cpp

I get the following error message, with "command not found" listed 5 times, as well as 2 other errors:

/hector_imu_attitude_to_tf/src/imu_attitude_to_tf_node.cpp: line 5: std::string: command not found

It has been suggested to me that this is a dependencies issue, however i have used Rosdep to install all dependencies with no luck. Is there something I am not seeing? I assume it is something I have not set up properly as I assume the code from the Hector-SLAM repository is working fine. Many Thanks

That explains a lot! How do I build the package and start the node? I did run catkin_make, and also used "chmod +x imu_attitude_to_tf_node.cpp" to give the file execution rights.

These appear to be questions that would have been answered by the introductory tutorials. In short: cd to the root of your workspace and then run catkin_make (after having run source /opt/ros/kinetic/setup.bash).

and also used "chmod +x imu_attitude_to_tf_node.cpp" to give the file execution rights.

No. That's not how this works.

This is C++, not Python or a shell script.

I'm afraid I'm not familiar with running C++ files so thank you for your explanation. I have now resolved the issue. Thanks again
