Hi,

I'm trying to rosmake a self-written node in Hydro on armhf, but it fails on a missing CvBridge.h. "roscd cv_bridge" takes me to /opt/ros/hydro/share/cv_bridge$ and "ls" shows cmake and package.xml. So where is the header file ?

Thanks,

building vision-opencv en cv-bridge bring the message that the stacks are not found and it assumes the new build system is being used. Also the catkin stack is not found, while ros-hydro-catkin is installed and newest version. So if Hydro indeed does support rosbuild, why is it asking for catkin?

You're also using the old CvBridge API, which has been deprecated for a long time, and which was removed starting in Groovy. See: https://github.com/ros-perception/vis...

With catkin, package headers are installed into /opt/ros/hydro/include/PACKAGE; you should be able to find the new cv_bridge headers there.

You can also list all of the files installed by a package with dpkg -L ros-hydro-cv-bridge

Ok, ty. I found I made a mistake in my code. I first had cv_bridge.h, then according to info I found, I had to use CvBridge.h. Changing back to cv_bridge, it compiles fine. From your info, I guess catkin is used next to rosbuild ?

cv_bridge (and all of Hydro) is built and released with catkin. You can use it from both catkin and rosbuild packages.
