can you package this as an addon (ie, not a project) :)

SDK version in this project is 2.0.3.
Current SDK version is 2.2.4.
I can probably update it to 2.2.2 (at least for linux64) and make a pull request in a bit.

Also the copyright date for Leap on the readme needs to change, as it is 2015.

I'm running ofxLeapMotion on openframeworks 0.8.0 with leap motion software version 1.1.3. When I run the visual studio 2012 example project, I get the following error. Any idea why this is happening? Thanks a lot!

Hello,

Thank you for your thorough work on ofxLeapMotion addon.

Not sure what is wrong on linux under your config,

we needed this beautiful controller working under unix,

this works:

LeapMotion Linux SDK version 2.3.1+31549
s373@20ff1b1

Fix ofxStrip
s373@9f1f3a0

example0 linux64
s373@518a195

32bits still not tested, but it holds same x86 lib from Leap SDK x64 version 2.3.1+31549, x86 version.

Best regards,

AS

hey,

issue solved
:)

Upon app exit, I occasionally receive this error. Going to send off to Leap support. Looks like an issue with the lib.

App crash:

Hi theo, i do not get any data with the ofxLeapMotion example. I just see the black grid and thats it. Leapmotion is runnig, my Javascript Leapmotion example is running and even restarting the Leapmotion service does not help. Any advice is greatly appreciated. thanks.

I am struggling on adding ofxLeapMotion on my project.
Already changed the .qbs file.
of.addons: [
'ofxOsc','ofxLeapMotion'
]

The folder is on the addons.
I try to build and it tries to load but it says .
👎 error: error: ../../../addons/ofxLeapMotion/libs/lib/linux64/libLeap.so: No such file or directory

The file is there I am not sure if I should add anything else to the project qbs file

It seems that there is an issue with the library not loading:
dyld: Library not loaded: @loader_path/libLeap.dylib

Any chance someone has already done this and can share? I'd be happy to do it if someone could provide some guidance.

Thank you.

It appears that gestures are now in place, but how do you use them? a small example or notes in the text would be really helpfull
