Build error

[Neopentane1]

Hello,
I can't build the new matleap.cpp (changed 15 days ago). I get the following errors:

There are many many lines of errors like the above.

Is it possible to upload the compiled matleap.mexw64? I have had trouble with this for some time and can't figure out why the build fails.

Thanks,
Eric

Hi, It looks like it can't find the SDK library. That's what "undefined reference" usually indicates. Thanks, Jeff

Jeff,
The SDK and all of its sub-folders are included in Matlabs path:

Hi Eric,

I was able to solve this same problem by changing my compiler from 'MinGW64 Compiler (C)' to 'Microsoft Visual C++ 2010 (C)'. I just had to install Microsoft Visual Studio 2010 and change the compiler in Matlab by running 'mex -setup' and follow the prompts.

My best,

Sean

Hi @sdevMasi,

Alongside using the compiler 'Microsoft Visual C++ 2010 (C)', what version of MatLab where you using?

Hi, I had the same issue.
I downloaded Matlab R2016a because it is compatibile with the compiler Microsoft Visual Studio Professional C++ 2010 (C).

I used Leap Motion Orion V3 and copied the file Leap.dll inside the same folder of test_matleap.m (as written in the GitHub page).

My pc is running Windows 10.

Step by step tutorial

1. https://visualstudio.microsoft.com/it/vs/older-downloads/ dowload Visual Studio 2010 Professional: during the installation select ONLY "Components for c++"
2. https://developer.leapmotion.com/releases/leap-motion-orion-321-39frn-3b659 Download Leap Motion V3 and download it
3. https://it.mathworks.com/downloads/web_downloads select R2016 to download that version of MatLab
4. Open Matlab, with the command mex -setup c++ check if Matlab uses the same compiler as Visual Studio 2010
5. Copy the folder LeapSDK from the website to the same folder of the project and copy Leap.dll from \matleap-master\LeapSDK\lib\x64 to matleap-master
6. In Matlab go to matleap-master, right click on the folder LeapSDK, select "Add to path" and then "Select Folders and subfolers"
7. Run build command
8. Run test_matleap command with the Leap Motion plugged in
