integrating phidgets. c++ dll inside of mono

Unity Engine
1

I have been trying to integrate the phidgets library with my unity project all day and I keep getting:

DllNotFoundException: phidget21.dll
Phidgets.InterfaceKit…ctor ()
PhidgetController.Start () (at Assets/FPB/Scripts/PhidgetController.cs:29)

I have added Phidget21.NET.dll to my Plugins folder and I get code completion in mono just fine. no compile errors.

When the app runs I get the exception.

Reading through the forums I have tried adding the phidget21.dll to the following directories:
/Applications/Unity/Unity.app/Contents/Frameworks/Managed
path/to/project/
path/to/project/Assets
path/to/project/Assets/Plugins

I have also tried using [DllImport (“/Applications/Unity/Unity.app/Contents/Frameworks/Managed/phidget21.dll”)], but i don’t think i fully understand how this works as I am trying to import the whole ell not just a single method like the examples i have seen using DllImport.

I have read through the various phidgets documentation for integrating with mono, but following that didn’t seem to help. I have seen quite a few people say they have gotten this working, but not any examples on how to get it working.

Thanks in advance for any help. very stuck right now.

Hey loafer, did you ever find a solution to this, as I am having the same trouble. I think it’s something to do with monodevelop’s/mono’s compatibility with .NET but I am unsure about these things. Please reply to me if you did find a solution, I’d be VERY grateful! Thank you!
