I built shark library from Git Source.(with visual studio). Added the include files.

wrote a simple code `

#include <shark/Algorithms/Trainers/CSvmTrainer.h> // the C-SVM trainer
#include <shark/Models/Kernels/GaussianRbfKernel.h> //the used kernel for the SVM
#include <shark/ObjectiveFunctions/Loss/ZeroOneLoss.h> //used for evaluation of the classifier
#include <shark/Data/DataDistribution.h> //includes small toy distributions
#include <shark/Data/Csv.h>
#include <shark/Algorithms/Trainers/LDA.h>
#include <shark/ObjectiveFunctions/Loss/ZeroOneLoss.h>
#include "stdafx.h"

using namespace shark;
int main(int argc, char **argv) {
  ClassificationDataset data;
    try
    {
        importCSV(data, argv[1], LAST_COLUMN, ' ');
    }
    catch (...)
    {
        exit(EXIT_FAILURE);
    }

    ClassificationDataset test = splitAtElement(data, static_cast<std::size_t>(0.8*data.numberOfElements()));
}
`

I get these errors shark: namespace does not exists Cannot open file shark/core/shark.h Classification identifier not declared

Checked the include file, all I see is "shark.h.in"

Whats the Issues? The last time i asked, A shark official told me latest shark is version 4.0.0

The Website http://image.diku.dk/shark/index.html is showing 3.0.0<-<-<- (Whats this guy saying?)

Hi sometimes Visual Studio Can be a little bit weird, make sure "stdafx.h" is at the top

I assume the following:

you have not installed shark after building
you are also not generating your VC solution using CMake

In that case, you need to add the generated Shark.h file to your include path. The path is likely something like $SHARK/build/{Debug or Release}/include/shark
