Couple of questions:
Did you selectively build just the ros2socketcan_bridge package (i.e. using colcon build --package-select ...)?
If so, did you build the can_msgs package before that?

[wangxianggang1997]

yes , I build the can_msgs packages success firstly by colcon build --packages-select can_msgs，then I build ros2socketcan_bridge package by colcon build --packages-select ros2socketcan_bridge but it occurs the error like Issue 6. but I don"t know why | | ***@***.*** | | ***@***.*** |

Hey, sorry for the late reply. I have written my own implementation that works pretty well. I can share it with you if you're interested. It is a repo on my github. Let me know and I can help you build and configure it. Cheers!

The compiler error is caused by the missing of qos parameter. I've succeful compile the code modifying the create_publisher and create_subscription like this:
this->create_publisher<can_msgs::msg::Frame>(topicname_receive.str());

to this:

this->create_publisher<can_msgs::msg::Frame>(topicname_receive.str(),1);
