Building ROS2 master on Ubuntu 16 fails

Hmm, really weird. It was a complete fresh checkout. Created a new directory, new src, imported the repositories and ran ament. When I do the same thing with beta1 (different workspace, but clean checkout as well), everything compiles fine. However master fails with the error above.

Hmm that’s really weird.
I just did the exact same thing:

1. create a new workspace: mkdir -p test_master_repos_ws/src && cd test_master_repos_ws
2. wget https://raw.githubusercontent.com/ros2/ros2/master/ros2.repos
3. vcs import src < ros2.repos
4. run ament: src/ament/ament_tools/scripts/ament.py build --build-tests -s
   and everything built fine

@Snowman

Is there any other document describing how to build master of ros2? Perhaps the list maintained in https://raw.githubusercontent.com/ros2/ros2/master/ros2.repos is not correct?

This repo files is the one used by the buildfarm and it looks like all jobs built fine last night (nightly [Jenkins]) so I doubt this is the problem.

The only thing I can see would be missing dependencies. Can you try to install all the packages listed in GitHub - ros2/ros2: The Robot Operating System, is a meta operating system for robots. ? there were a few changes since beta1.

Sorry I know you are repeating yourself, if installing all the dependencies don’t fix it, could you provide the list of commands you ran with the exact arguments rather than a description, that would make it easier to reproduce

Thanks!
