Are you using the compilers provided by conda-forge to compile the code? Can you report the content of your environment (i.e. micromamba list
)? In theory you should not need to set LD_LIBRARY_PATH
to ensure that the loader can find librclcpp.so
. However, the location of the library you report is strange, if you environment is ros_env
you should be able to find the library at micromamba/envs/ros_env/lib/librclcpp.so
.

I think no. which g++
points to /usr/bin/g++
. But you have a point there. I installed micromamba install compilers cmake pkg-config make ninja colcon-common-extensions
and this now points to the compiler in the environment.
... and this actually solved the problem :-) lddtree install/image_tools/lib/image_tools/showimage
is now showing the resolved library:
showimage => install/image_tools/lib/image_tools/showimage (interpreter => /lib64/ld-linux-x86-64.so.2)
librclcpp.so => $HOME/micromamba/envs/ros_env/lib/librclcpp.so
and I can run ros2 run image_tools cam2image
without issues. Thanks.
I the ROS repos, there is a convenient package ros-dev-tools
that will install all required build tools to build packages. It would be nice if this could be available too for robostack.

You are right, the library is at micromamba/envs/ros_env/lib/librclcpp.so
. I forgot to update the index before searching for the file.

That makes indeed sense (even at conda-forge levels, if colcon is removed). I find myself installing complers cmake pkg-config make ninja
everywhere, having something like build-essential can be useful.
