Build Error about crazyswarm HOT 6 CLOSED

• We are using Ubuntu 16.04 with ROS Kinetic. That includes gcc 5.4.0. That being said, we had earlier versions running with Indigo just fine and I can't think of a reason why it shouldn't work with Indigo in the latest version.

• It looks like the master-branch didn't reference the correct/latest version of the crazyflie_ros submodule. I fixed that and the errors which you manually corrected should be gone now.

• For your issue, make sure you run a "catkin_make clean" before you run "catkin_make" in "crazyswarm/ros_ws". Also, don't checkout the crazyswarm repository as part of a ROS workspace. The repository contains it's own ROS workspace (namely in the ros_ws folder). Putting a workspace inside another workspace might create some unwanted side-effects. (Not sure if that explains the errors you are seeing, but might be worth a shot.)

• If you are using OptiTrack, or you are interested in using another external localization system other than VICON, you can look at our "libmotioncapture" branch.

Hope that helps - let me know if you run into more issues!

I'm still getting the same class errors. There always while building the crazyflie_server.cpp file, and in the libobjectracker included files. The vicon_ros issues are all fixed.

Let me know if there is anything else you think I should try or any outputs that might be useful.

Could you pipe the full output of catkin_make to a file and attach it here?

Seems to be related to this: http://stackoverflow.com/questions/28775673/why-cant-i-move-stdofstream
If you remove all occurrences/uses of "m_outputCSVs" in crazyflie_server.cpp it might compile just fine even with an older gcc.

Commenting the instances of m_outputCSV looks to have fixed the issue. I'm no longer getting any errors during the build.

Thanks for all the help,
