I followed the instruction OPEN_SOURCE_CODE_README, and stop at last step build package in ros2_overlay_ws

from ros2_openvino_toolkit.

@portgasray
Can you check if there is a $CPU_EXTENSION_LIB variable in your environment?
This problem is mainly caused by the absence of the relevant variable of openvino, you followed the OPEN_SOURCE_CODE_README, so you should export the variable like this:
export InferenceEngine_DIR=/opt/openvino_toolkit/dldt/inference-engine/build/
export CPU_EXTENSION_LIB=/opt/openvino_toolkit/dldt/inference-engine/bin/intel64/Release/lib/libcpu_extension.so
export GFLAGS_LIB=/opt/openvino_toolkit/dldt/inference-engine/bin/intel64/Release/lib/libgflags_nothreads.a

from ros2_openvino_toolkit.

Thank you for your help, Although I put these env in a file that convenient for me to source, I can hardly connect it with the problem here.
As you say, I followed your suggestion and compiled the ros2_overlay_ws successfully (I had already deleted the ros2_intel_realsense part, due to the refactor branch has some problem to me)
Thank you all @RoboticsYY

Thank you, @RoboticsYY for bridging.
Thank you, @RachelRen05 for answering.
We are now in the progress of updating README files, in order to make them clearer and easier to understand.
I'd close this issue. and please feel free to reopen it if anyone has more comments.
