Link ifm3d library files with another ros package when using ros-<distro>-ifm3d-core

[tanay-bits]

Hi,

I installed both the ifm3d ros wrapper as well as the driver package from apt using apt install ros-melodic-ifm3d.

I want to use the core (driver) libraries components such as ifm3d::Camera, ifm3d::FrameGrabber, etc. in my custom ros package. I have included ifm3d as a catkin package in my package's CMakeLists.txt as well as package.xml, but AFAIK that refers to just the ros wrapper -- https://github.com/ifm/ifm3d-ros and gives access to the msgs from it.

When I run catkin_make in my workspace, it is failing when it tries to link my node with ifm3d driver libraries, as it cannot locate the .so files.

What is the correct way to link ifm3d core libraries in this situation? Since the ros package ifm3d_core does not provide any cmake files, including that in my CMakeLists doesn't help.

Hey tanay-bits,

could you please provide some background information like which ROS version are you using and how the ifm3d package was installed. Have you used the ifm apt repositories or the ROS distribution?

While we developped the packages for the ROS index we ran into an issue with the naming. This was why the ifm3d base library is called ifm3d_core and the ifm3d ROS wrapper is called ifm3d.

Am I right you don't want to use our ROS driver but you are planning to develop your own ROS wrapper which uses the ifm3d_core libraries. Would it be fine to provide an Docker container with an example set-up?

Best,
Christian
