I think ros2arduino is a wonderful project. I thought trying it, but I will not move so I want you to follow me.

Hi, @nnn112358,

Did you install ROS2 by binary package? Or did you install with source build?

nnn112358 commented 5 years ago

I use a Building ROS 2 on Linux. https://index.ros.org/doc/ros2/Installation/Linux-Development-Setup/

By the way, when I used the latest version of Micro-XRCE-DDS-Agent, I solved it.

$ git clone --recursive https://github.com/eProsima/Micro-XRCE-DDS-Agent/ 
$ mkdir build && cd build
$ cmake -DTHIRDPARTY=ON -DCONFIG_UDP_TRANSPORT_MTU=4096 -DCONFIG_SERIAL_TRANSPORT_MTU=4096 ..
$ sudo make install
$ sudo ldconfig /usr/local/lib/

I'll check this again and update the document.

Thank you for your feedback :)
