error to load dll API using load libary

I'm trying to load dll library of commands in order to connect to software api but when i load it i got errors although previous versions of the api and software did work

I tried in Matlab 32bit and it worked but in matlab 64bit it doesn't

my code is

    addpath('C:\Program Files\OptiTrack\Motive\lib'); % change if necessary
    addpath('C:\Program Files\OptiTrack\Motive\inc'); % change if necessary

    [notfound,warnings]=loadlibrary('NPTrackingTools','NPTrackingTools.h')

in "lib" folder you can find 2 dll's "NPTrackingTools.dll" and "NPTrackingToolsx64.dll" and 2 lib files "NPTrackingTools.lib" and "NPTrackingToolsx64.lib"

in "inc" folder you can find 2 header files "NPTrackingTools.h" and "trackablesettings.h" i attached them as text files

I'm using win7 64bit with matlab 2014a 64 bit i tried different mex compilers: Microsoft Windows SDK 7.1 (C++) and Microsoft Visual C++ 2013 Professional. but got the same errors.

more background information: I'm trying to close loop of control system that get position of Quad-copters from Optitrack cameras and Motive software. i already succeed connecting throw NatNet interface API in Simulink but failed on using in Real-Time Windows Target and matlab support told me it's problematic to implement in Real-time mode Simulink because this API use .NET DLL so now I'm trying to make the other API to work because it's normal DLL and not .NET.

the errors i got is

Error loading library intermediate output follows.
The actual error is at the end of this output.

Thank you Or Hirshfeld אור הירשפלד

Answer 1

[Or Hirshfeld]

There is many problem with the header so it need to be edit

see the solution on GitHub and MatlabCentral

http://www.mathworks.com/matlabcentral/fileexchange/49921-natural-point-motive--optitrack--api-interface-to-matlab-and-simulink-64bit-by-or-hirshfeld

Answer 2

[Philip Borghesani]

Those header files contain c++ classes which are not supported by loadlibrary. I very much doubt they worked or would work using loadlibrary with 32 bit MATLAB. You will need to find a C interface you can use or write a mex file.

[Or Hirshfeld]

thanks for the answer

but it actually work in matlab 32bit but not in matlab 64bit
