ERROR Building in Humble: error: ‘struct rclcpp::PublisherEventCallbacks’ has no member named ‘matched_callback’

[PlayWeird]

I'm trying to build your image_pipeline from source but keep getting this error. Any help would be appreciated. I'm currently using ROS2 Humble and have cloned the humble branch.

Could you double check if you are on the humble branch? The default cloned branch is rolling so you might be on humble. I am able to compile fine on the latest commit based of humble.

The rolling branch has the line that throws you the error but it is not part of the humble branch.

[mikeferguson]

@samuel-ongzx is correct here - you need to use the correct branch - humble branch is passing CI so there should be no issue once you switch to that.

I checked and you were correct. My issue was that I was switching to the humble branch on the GitHub page thinking that the HTTPS link was also switching to that branch. Thanks.
