Catkin Dependency

[JosephSpires]

Hi,

I am trying to build this on ROS2 humble on Ubuntu 22.04, but

"rosdep install -i --from-path src --rosdistro humble -y"

returns:

ublox_msgs: Cannot locate rosdep definition for [message_runtime] ublox_msg_filters: Cannot locate rosdep definition for [catkin] ublox_gps: Cannot locate rosdep definition for [tf] ublox_serialization: Cannot locate rosdep definition for [roscpp_serialization] ublox: Cannot locate rosdep definition for [catkin]

I tried to install catkin and have been met with:

The following packages have unmet dependencies: python-catkin-pkg-modules : Conflicts: catkin but 0.7.8-1 is to be installed python-catkin-pkg : Conflicts: catkin but 0.7.8-1 is to be installed

...I've tried a few things but no joy.

Any idea what I'm doing wrong?

Cheers Joe

I've the same error, seems like it's fixed in galactic-devel and ros2 branches.

Yeah I have got it to build in the past with git clone -b ros2 ...

Hey !

I am getting the following error

I am also getting this error when building from a clean pi now, didn't before

Any idea which ROS2 version is currently working?

So we recently merged support for RTCM messages into the main ros2 branch. Unfortunately, rtcm_msgs has been having trouble building on the buildfarm, hence the error above. My latest fix should make it build once it is released.

In the meantime, if you checkout both rtcm_msgs and this repository, you should be able to build just fine:

mkdir -p ublox_ws/src
cd ublox_ws/src
git clone https://github.com/KumarRobotics/ublox -b ros2
git clone https://github.com/tilk/rtcm_msgs
cd ..
colcon build

@clalancette I will give it a go, thank you!

It looks like the humble-devel branch is mistakenly on the ROS1 branch (master)

[clalancette]

Yes, good point. Since we don't use that branch anywhere, I've now removed it.
