[quote="mch, post:4, topic:2195"] Not sure what is RPATH. Is it env. variable? I can't see this variable set after I sourced ~/ros2-osx/setup.bash. I tried to set DYLD_LIBRARY_PATH manually but, as you said, it isn't helping due to SIP. [/quote] RPATH is something that is contained within shared libraries, see: - https://blogs.oracle.com/dipol/dynamic-libraries,-rpath,-and-mac-os - https://cmake.org/Wiki/CMake_RPATH_handling You could try using `install_name_tool` to change the `libfastrtps.1.dylib` reference in your `/Users/mc/skynet-edge/core_ws/build/skynet/test/skynet_test` executable to be `/Users/mc/ros2-osx/lib/libfastrtps.1.dylib`, or what ever the actual path is. --- [Visit Topic](https://discourse.ros.org/t/library-not-loaded-libfastcdr-dylib/2195/5) or reply to this email to respond.
