[Mono-list] Problem with Porting OpenCV to Mono

[Yoav Hacohen]

Hi,

 

I'm trying to translate the main part of OpenCVDotNet which is written in
managed C++ (and cannot be compiled using clr:safe) to C# using P/Invokes.

I have encounter the following exception:

 

Stacktrace:

 

  at (wrapper managed-to-native) OpenCVDotNet.PInvoke.cvGetImageROI (intptr)

This application has requested the Runtime to terminate it in an unusual
way.

Please contact the application's support team for more information.

 

Under .Net it runs fine.

 

To run this example you can download the code from
https://opencvdotnet.googlecode.com/svn/trunk/src/sandbox , and have the
original OpenCV Dll files (Usually at C:\program files\OpenCV\Bin\) in your
C:\windows\System32\  folder.
