Hi, I noticed that in my project every node with dynamic_reconfigure is rebuilt even if there is no file change. Is this a known behaviour of catkin? Is there anyway to prevent it?

Thanking you, Benzun

Edit: I thought I solved this issue but everytime i run dynamic reconfigure the headers are created again in the folder /devel/include/package_name.

I am using ros hydro on Ubuntu 12.04. I am just building the dynamic_reconfigure tutorial from http://wiki.ros.org/dynamic_reconfigu...

Everytime i run the build i get the following

Generating dynamic reconfigure files from cfg/Tutorial.cfg: /home/bpwiselybabu/drc_workspace/devel/include/dynamic_tutorials/TutorialConfig.h /home/bpwiselybabu/drc_workspace/devel/lib/python2.7/dist-packages/dynamic_tutorials/cfg/TutorialConfig.py

Even though I have not edited the cfg/Tutorial.cfg file

This does not happen with ros messages though.

This is not a known issue. If you want more help to figure out what is happening for you you might want to provide more information: Which version of ROS are you using? For which package do you experience the issue? What commands do you invoke, what is the actual output, what the expected?

Without more information, I don't see how anyone can help you.

I've seen this happen when the class name that is generated doesn't match the file name that generated it.

This is noted in the tutorial that you link to:

"NOTE: The third parameter should be equal to the cfg file name, without extension. Otherwise the libraries will be generated in every build, forcing a recompilation of the nodes which use them."

I had the same issue on ubuntu 14.04 / ros indigo. This solved it.

We had the same problem but we fixed it by adding _catkin in the following line in the cfg file:

from dynamic_reconfigure.parameter_generator_catkin import *

I had converted an old package to catkin and had missed that you needed _catkin here.

Similar issue I was upgrading an existing package in catkin. but I already made the change you suggested, yet it occurs.

I just tested to remove _catkin and then it re-generated the dynamic_reconfigure files each time I run catkin_make. I tested it on Hydro.

This solved my problem (the parameter name was already matching the cfg name). Thanks a lot :)
