Instead of setting CMAKE_CXX_FLAGS directly, we should use features in newer cmake versions for enabling C++11 support. See #11 for some discussion.

The only thing stopping this right now is support for Ubuntu 14.04 which has older version of cmake (v2.8.12), so this should be done after EOL for that Ubuntu release.

When loading models in Qualisys while the node was running, the Qualisys node crashed with the error:

terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_M_construct null not valid

Hi,

Thanks for sharing! I am using your code to get the data from the qualisys mocap and many times I get the output "[ WARN] [1450178660.490998011]: Lose track of subject crazyflie" even though the mocap still outputs the correct values all the time, from what I can see. I was wondering if there was anything I could do regarding this issue?

Also, when setting up the parameters in qualisys.launch, I choose port "22223" but for some reason, it is displayed port 22222 when running the code as

"[ INFO] [1450179306.041624629]: Connecting to the Qualisys at: IP_ADDRESS:22222
QTM RT Interface connected
Version set to 1.7". If I try to change the value nh.param("server_base_port", base_port, 22222); in the QualisysDriver.cpp, to 22223 then I cannot connect to the mocap system.

Another question, is it that the default measurements are 6DOF with Euler angles?

I am running ROS Jade on Ubuntu 14.04 and I am using a crazyflie quadrotor.

Thanks for the help!

Creating and destroying threads at each frame seems like a lot of overhead, maybe can keep the threads running and signal it when new data arrives.

Is it possible to add a parameter to the driver so that it disables the filter and publishes a PoseStamped message?
Say I'm only interested in position and orientation but not velocity.

I updated from Ubuntu 16.04 to 18.04. Since my compiler is now gcc version 7.3.0, this error appears:

Apparently you can't compare pointers to integers.
