Hi, I have a cpp code with 3 header files for the same written by me. I want to port this code to ros including these header files in my package. I created a package with my .cpp code in src folder and changed the CMakeFile.txt to build the executable of the same. If i have to include these .h files as well to my code where do i place them in the package and how to build my code using the .h files.

Thanks, Karthik

The usual practice is to place your headers in include/package_name, referencing them like this:

#include <package_name/header_name.h>

You would fill in your own package_name and header_name, as appropriate.

They only need to be exported in the manifest.xml if other packages include them. Your question implies no need for that.

Thanks Joq. Ya i was missing the package_name in my include statement. It helped!!

+1 for the link to the usual practice; I always wondered if those were written down somewhere.

Hello!

If I understand you in the right way, everything is very-very simple. You only should to place your .h in /include directory. So, .cpp files will be in yourProject/src, .hpp will be in yourProject/include. And this is all! Ros building system should to find your headers by itself, if they mentioned in your .cpp files.

Hey thanks for the response. Are you using in similar way. I did try this and it was not working so i posted this question. Could you check once and reply back.

Hey it worked!! sorry i missed as small thing. When i created a project, it happened to create /project/include/project folder where i placed my .hpp files. But when i place it back to /project/include it worked.

You can use /project/include/project method. As example, I do next: /project/include/module1...N, then in .cpp #include "moduleX/header.h"
