Hi to everyone, we are working in a project involving the use of EMGU and in particoular the SVM functions of OpenCV and we have a problem using Mono on a Ubuntu platform and we don't have this problem on windows. The problem appears when we call the Emgu.CV.ML.SVM.Train method. All the parameters are correct and we canno't debug the wrapped code...

We have tried to increase the Shared Memory and other tricks but it doesn't work. Do you have any idea? Thank you Angelo
