Hi,

I want to build custom messages and services in ROS2 by using rosidl_generator

 find_package(rosidl_default_generators REQUIRED)

However I get following CMake error

 CMake Error at /opt/clion-2019.2.4/bin/cmake/linux/share/cmake-3.15/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
 Could NOT find FastRTPS (missing: FastRTPS_INCLUDE_DIR FastRTPS_LIBRARIES)

I tried to install ROS2 by Debian Packages and by Source. I also checked if rosidl_default_generators is installed:

 apt list--installed | grep rosidl-default-generators

 ros-dashing-rosidl-default-generators/now 0.7.0-1bionic.20191016.185016 amd64 [installed,upgradable to: 0.7.0-1bionic.20191210.230356]

What could be the problem ?

Thanks

Comments

A few things to clarify:

  • Can you please provide the full CMake output and not only the error message line
  • You say your installed ROS from debian packages AND from source. Which one are you using for this build ? and how did you install it exactly (a link to a tutorials or a list of commands would be useful)?
  • It looks like your packages are outdated, is there a reason for you not to upgrade all your ROS packages?
  • You seem to be using CLion, do you have the same behavior if you try to build from the command line?
  • Are you able to build official packages with custom messages, for example https://github.com/ros2/example_inter..., (make sure to use the dashing branch for the repositories you clone) or does that fail as well ?
