[Dune] Problem running DUNE course 2015 pdelab-exercise4sol

[Tatiana Kim]

Hi Christoph and Eike. Thanks for your help! Removing "Generic" from "GenericReferenceElements" solves the problem and I can compile the code without errors.

However, when I run ldom_examples, I get the following output:

parallel run on 1 process(es)
usage: ./ldom_example <cfg-file>


The first few lines of the ldom_examples.cc are:

int main(int argc, char** argv)
{
    std::cout << "Have " << argc << " arguments:" << std::endl;
    for (int i = 0; i < argc; ++i) {
        std::cout << argv[i] << std::endl;
    }
    
    try{
        // Maybe initialize Mpi
        Dune::MPIHelper& helper = Dune::MPIHelper::instance(argc, argv);
        if (Dune::MPIHelper::isFake)
            std::cout<< "This is a sequential program." << std::endl;
        else
        {
            if(helper.rank()==0)
                std::cout << "parallel run on " << helper.size() << " process(es)" << std::endl;
        }
        
        if (argc!=2)
        {
            if (helper.rank()==0)
                std::cout << "usage: ./ldom_example <cfg-file>" << std::endl;
            return 1;
        }


In my code, argc =1 - hence the output "usage: ./ldom_example <cfg-file>". The code then exits the program.

I am not an expert in C++ so not sure what the problem here might be. Any help would be much appreciated! 

Thanks,
Tatiana.

Hi Tatiana, hi Eike,
as stated in the release notes of 2.3
   http://www.dune-project.org/releasenotes/releasenotes-2.3.html
the GenericRefereceElements where deprecated and were
removed after Dune 2.3 as noted in the recent changes
   http://www.dune-project.org/recent_changes.html

I assume so, too.

Tatiana, please try to remove all the "Generic", that usually
solves
90% of the problems. If you still get stuck afterwards, report
back.

Bye
Christoph
