What's actually happening here is a ton of the repos aren't correctly cloned. From vcs status:

[danzimmerman]

Pulled all the sources again with vcs import --input https://raw.githubusercontent.com/ros2/ros2/jazzy/ros2.repos src. Building up to rcl now

[danzimmerman]

RCL build worked fine this time but now dying with

user@computer:~/.local/opt/ros/jazzy_ws $ colcon build --symlink-install --merge-install --cmake-args -DCMAKE_BUILD_TYPE=RelWithDebInfo --packages-up-to osrf_testing_tools_cpp

And for ament_package

'utf-8' codec can't decode byte 0xf5 in position 4: invalid start byte

[danzimmerman]

Oh this seems to be some kind of sourcing thing. If starting an incremental build like --packages-up-to rcl I should source the workspace before going forward (both of the above errors were cleared by deleting the build, install, and log folders).

Will wipe them out and do a full rebuild.

[danzimmerman]

Getting there [1h 31min 58.8s] [274/364 complete] [rclcpp:build 62% - 28min 52.7s]

[danzimmerman]

After full delete and rebuild everything went fine.

• Having issues with Reduce disk space used by ROS 2 build. #21 but the issues here are understood.

[danzimmerman]

I don't know what corrupted the repos in the first place, but will keep an eye on it.
