Day 3

1. Setup ROS development environment using Eclipse Oxygen
   • catkin config -G"Eclipse CDT4 - Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER_ARG1=-std=c++11 -D__cplusplus=201103L -D__GXX_EXPERIMENTAL_CXX0X__=1
   • bash -i -c "eclipse"
2. Discussed messages and nodes design
3. Switched back to QtCreator for new bambi ros package, because we noticed the catkin build tool support (not catkin_make)
4. Refactored bambi repository!
   • Created submodules for mavlink and mavros
   • Checked it in as whole catkin workspace
   • PROVIDED developer setup shell script (!)

LESSONS LEARNED

In a submodule we are initially detached from the original repository, i.e. git push will not push to the originating remote repository (which makes actually sense, since we are in a submodule and won't necessary change the original repository (we are formally not working on them). So any commit in the submodule will result in a HEAD DETACHED state.

If we anyhow want to commit to the main repository of the submodule we have to checkout first:

1. git checkout <original-branch> e.g. release/kinetic/mavlink

To fix head detached state:

1. git checkout <original-branch> e.g. release/kinetic/mavlink --> Previous HEAD position was fdea82a...
2. git merge <your-temporary-branch-number-from-head-detached> with head position number from point 1
3. git push
