@dewagter the build fails while in the pre-install phase, sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa -y and sudo apt-get install -y --force-yes paparazzi-dev paparazzi-jsbsim gcc-arm-embedded gcc-arm-linux-gnueabi g++-arm-linux-gnueabi libipc-run-perl rustc cargo libgazebo9-dev libgps-dev. Is this a Travis issue? I can't recreate it locally, and I see #2592 had a similar issue in one of the earlier commits

[dewagter]

Build error seems quite unrelated to the commits.

Is being addressed in #2594

@matteobarbera
Can you pay special attention to the waypoint_set_ functions which were waypoint_move_ functions in the tudelft branch.

[matteobarbera]

The mavlabCourse2019 branch in the tudelft repo does not have the waypoint_move_here_2d function defined, it's lagging behind paparazzi/master by a lot of commits

[gautierhattenberger]

can you rebase on top of master to get #2594 changes ?

[matteobarbera]

I've changed the waypoint_set_here_2d function with the more recent ones, and rebased to get the travis changes, but I can't edit the pull request directly. https://github.com/matteobarbera/paparazzi/tree/matteobarbera/update_course_rebase
