Building dynamixel_workbench_toolbox without ROS on a Raspberry Pi

[swinterbotix]

While following the instructions to build the dynamixel_workbench_toolbox package without ROS on a Raspberry Pi, I ran into the following error (while running the 'make' command).

After some debugging, I found that if I changed line 20 in the CMakeLists.txt file to read...

target_link_libraries(dynamixel_workbench LINK_PUBLIC "/usr/local/lib/libdxl_sbc_cpp.so")

... then the 'make' command worked.

I'm not exactly sure how it should be done, but I believe that the 'if condition' block should check to see not just if the code is being built on a MAC or x64 Linux system, but also a SBC system (like the raspberry Pi).

Hey I had the same issue but your solution didn't work for me. I get the same error but with a different name:
make[2]: *** No rule to make target '/usr/local/lib/libdxl_sbc_cpp.so', needed by 'find_dynamixel'. Stop.
make[1]: *** [CMakeFiles/Makefile2:108: CMakeFiles/find_dynamixel.dir/all] Error 2
make: *** [Makefile:84: all] Error 2

Please help!
Thank you !!

Hi @swinterbotix
Sorry for the delayed response.
The issue seems to be caused by a whitespace on line 56 of the c++/build/linux_sbc/Makefile, which resulted in the make command failing. This has been fixed in pull request #634.

Additionally, you can modify the CMakeLists.txt file to ensure it builds without issues on SBCs (like the Raspberry Pi). Add the following line at the specified location:

dynamixel-workbench/dynamixel_workbench_toolbox/examples/CMakeLists.txt

Line 19 in 31f1c97

elseif(CMAKE_SYSTEM_PROCESSOR MATCHES "arm" OR CMAKE_SYSTEM_PROCESSOR MATCHES "aarch64")

Thank you for raising the issue!
