[Dune] Problem with GmshReader

[Jayesh Badwaik]

Hi,

I am using the GmshReader to read .msh files
and have written the following code to read a msh file

         static const int dim = 2;

         typedef Dune::ALUSimplexGrid<dim,dim> GridType;
         typedef GridType::LeafGridView GV;

         typedef GridType::ctype ctype;

         GridType grid(100);
         std::string gridName = "./grids/2Dfile.msh" ;
         Dune::GmshReader<GridType> gmshreader;
         gmshreader.read(grid, gridName);


however the code is not working and outputs the error as shown below:

finiteelements.cc: In function ‘int main(int, char**)’:
finiteelements.cc:258: error: invalid initialization of non-const reference
of type ‘main(int, char**)::GridType&’ from a temporary of type ‘int’

>::GridFactory(const Dune::GridFactory<Dune::ALUSimplexGrid<2, 2> >&)

what could be the reason for the error??

Cheers and Regards,
