Hi, i've been trying to develop a Cython interface for a C++ graph cut implementation.
I have one class named *GCOptimization* and a child class named * GCoptimizationGeneralGraph* and except from the constructor all the others methods belong to *GCOptimization. *Reading this thread ( http://wiki.cython.org/WrappingCPlusPlus) I found that I might have problems calling those methods, actually i'm having "segmentation fault" problems and I don't know if it is because i'm calling a method from a parent class or something else. for example, this is the class I defined (setDataCost method belongs to * GCOptimization* not to* **GCoptimizationGeneralGraph)* ctypedef struct c_GCoptimizationGeneralGraph "GCoptimizationGeneralGraph": void setDataCost(double *DataCost) c_GCoptimizationGeneralGraph *new_GCoptimizationGeneralGraph "new GCoptimizationGeneralGraph" (int num_pixels,int num_labels) void del_newGCoptimizationGeneralGraph "delete" (c_GCoptimizationGeneralGraph *optimization) cdef class GCoptimizationGeneralGraph: cdef c_GCoptimizationGeneralGraph *optimization def __new__(self, num_pixels, num_labels): self.optimization = new_GCoptimizationGeneralGraph(num_pixels, num_labels) def __dealloc__(self): del_newGCoptimizationGeneralGraph(self.optimization) def setDataCost(self, dataCost): cdef double *temp = <double *>dataCost.data self.optimization.setDataCost(temp) The question would be, could I have a problem with this? And in case I do, how could I define the the parent/child relation in cython Thanks, Marco
