ros_gz_bridge can't compile on humble/garden: rosidl_pycommon on Ubuntu 22.04, Win10 WSL2 about ros_gz HOT 5 CLOSED

Right, binary is easier, but there wasn't such a combination listed for my case: humble + garden. (I finally compiled with the humble branch, rosidl error happened to has been with the ros2 branch which I thought was humble). As of RAM I had plenty (32 GB), but I use to fill it with stuff and RAM disks. I mentioned that for anyone else who encounters WSL crashes while building, it could be out of memory error and nothing with the source or compatibility, but sometimes it is not clear, because the WSL consoles just suddenly return to Windows.

I tried a partial workaround:

ros2 run ros_gz_image image_bridge /rgbd_camera/image /rgbd_camera/image

The topics appear in rqt_view

• However without images with gz sim:

gz sim -v --render-engine ogre sensors_demo.sdf

...

• WIth ign gazebo the images show up:

ign gazebo -v --render-engine ogre sensors_demo.sdf

Maybe I figured it out - I checked again, I discovered that git branch displayed ros2, IDK why. Re-cloned properly and this time it did complete (it takes a lot of RAM/page file though).

Then it didn't work until I read the bridge command from the example carefully - I noticed that the declared type was for Ignition, that's why it works only with ign...

It should be gz.msgs.Image, not ignition.msg.Image.

ros2 run ros_gz_bridge parameter_bridge /rgbd_camera/depth_image@sensor_msgs/msg/[email protected]

Please update the examples. Thanks

Yes, there are a lot of things happening at compile time with templates. The binaries are suggested if you are on a limited platform.

It should be gz.msgs.Image, not ignition.msg.Image.

Depending on the branch, it should be compatible with both. Which branch did you end up using?

I don't think there's any remaining issue here, so I'll go ahead and close it
