Hi

I get this error :

CFRadioController.h :
Lexical or Processor issue
"thread not found"
In the file include from /Users/.../flightdynamics/CameraDetection/CFRadioController.cpp:10:

I am running on OSX 10.10 and xcode 6.3.2

Sorry I thought you are talking about CFRadio lib, you got this error because you need to enable C++ 11 support for <thread>

HI,

Now on Xcode in "build setting" on C++ Standard Library i set : libc++ (LLVM C++ standard library withC++11 support)
With this setting i get some errors :

Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64

That's why initialy I had changed "libc++ (LLVM C++ standard library withC++11 support)" with libstdc++(GNU C++ standard library)


Sorry it seem not easy to use for me, I don't have developer experience.

The video looks great, but the link to bitbucket is dead. Any chance you can make it public again?

This link should work: https://bitbucket.org/flightdynamics/crazyflie
(found it in the comments of the YouTube video)

Hello, nice work
I am a developer too, i want to know how to send the data of the sensor(camera) to the drone ?
could you explain me how to calculate the error.
How do you set the desired points ?
Thanks
