Wiki example error

[nyckmaia]

I copy and paste your Wiki example and I did a little adaptation to use it on a new Qt Console application.

#include <QCoreApplication>

#include <hdffile.hpp>
#include <hdfdataset.hpp>
#include <boost/shared_ptr.hpp>
#include <vector>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    hdf::HDFFile<> file("test.h5", hdf::HDFFile<>::truncate);
    std::vector<double> data(100,1.0);
    std::shared_ptr<hdf::HDFDataSet<> > dataset =
            file.writeDataset<double>("doubledataset", data);

    return a.exec();
}

In this line:

std::shared_ptr<hdf::HDFDataSet<> > dataset =
            file.writeDataset<double>("doubledataset", data);

I got these 2 errors:

error: C++ requires a type specifier for all declarations
error: expected '(' for function-style cast or type construction

What I have to do?
