Error: no matching function for call to 'Get'

Bug report

Following the steps for compilation for the main branch, humble release, gives this error:

Finished <<< rmf_traffic_editor_test_maps [2min 23s]
--- stderr: rmf_building_sim_gz_classic_plugins
/home/user/rmf_ws/src/rmf/rmf_simulation/rmf_building_sim_gz_classic_plugins/src/door.cpp:36:22: error: no matching function for call to 'Get'
auto _ros_node = gazebo_ros::Node::Get(sdf, node_name);

Seems that the gazebo classic elements are not compatible with the ones installed for gazebo 11.

Solved it by replacing the code:
_readonly_common->init(gazebo_ros::Node::Get(sdf, node_name));

By:

_readonly_common->init(gazebo_ros::Node::Get(sdf));

The change was introduced here as part of Humble compatibility.

Can I check with you what's your ROS version, and the version of ros-<distro>-gazebo-ros?

Hi, Sorry for the late response, last month we just pushed for a deadline and didn't see your message I'm afraid.

My version is Humble
user:~/ros2_ws/src$ ros2 pkg xml gazebo_ros | grep version
3.6.0

Just run it again in a fully Ubuntu 22, Humble stock system and same issue. I'll try to push this fix to our fork and do a push request,

i am having the same issue. for me Ubuntu 20.04, ROS2 version is galactic. And the gazebo_ros package version is 3.5.2. And i am following the build from source instructions as listed here except for distro i am using galactic. When i try to do it with Humble, i get a different set of errors but i am suspecting that may be due to the fact that i am still on Ubuntu 20.04 and not 22 yet.

Has the galactic branch been released? i saw in the migration thread a comment saying that the galactic branch has not yet been released.

As mentioned above, main only supports humble. There is a galactic-devel branch you can checkout for source builds with galactic. You should keep in mind that ROS 2 Galactic will be EOL by end of November so we do not plan to support any galactic releases.
