"I know that I compiled this using the Buildroot from Rockchip, so I can only work based on this compiled base."

Ultimately, there's a bug here, unable to generate cross-compilation chain's link libraries. Only x86 ones can be generated.

I just need to add the line 'SUFFIX ".cpython-38-aarch64-linux-gnu.so"' after 'set_target_properties(${_library_name} PROPERTIES', but I've broken the build chain dependency. My understanding of CMake is not very deep. Starting >>> rclpy...

Maybe my understanding is incorrect, I suspect that the CMakeLists file does not match the generation of linked libraries for cross-compilation.

Although cross compile is not supported, every compilation passes the cmake parameter. Can we obtain these parameters to generate a linked library. I have compiled all packages for ROS2, and...

@clalancette Others should use the following two parameters passed by colcon to define the generated file "-DCMAKE_SYSTEM_PROCESSOR=aarch64" “-DPYTHON_SOABI=cpython-36m-aarch64-linux-gnu”
