[Trilinos-Users] Teuchos link error with Xcode

[Sensei]

An addition to the problem.

It seems I cannot create an Epetra_Map correctly. In addition to the 
code I've posted, which cannot be linked for some missing identifiers, 
I've found a weird error.

If I create a map, be either with RCP or standalone, it crashes.

Take a look at this code, crashing when accessing a map:


#include <iostream>

#include "mpi.h"

#include "BelosConfigDefs.hpp"
#include "BelosLinearProblem.hpp"
#include "BelosEpetraAdapter.hpp"
#include "BelosBlockGmresSolMgr.hpp"

#include "Epetra_Map.h"
#ifdef EPETRA_MPI
#include "Epetra_MpiComm.h"
#else
#include "Epetra_SerialComm.h"
#endif
#include "Epetra_CrsMatrix.h"
#include "Teuchos_CommandLineProcessor.hpp"
#include "Teuchos_ParameterList.hpp"
#include "Teuchos_StandardCatchMacros.hpp"

int main(int argc, char * argv[])
{
     int rank = 0;

#ifdef EPETRA_MPI
     // Initialize MPI
     MPI_Init(&argc,&argv);
     Epetra_MpiComm Comm(MPI_COMM_WORLD);
     rank = Comm.MyPID();
#else
     Epetra_SerialComm Comm;
#endif

     typedef double                            ST;
     typedef Teuchos::ScalarTraits<ST>        SCT;
     typedef SCT::magnitudeType                MT;
     typedef Epetra_MultiVector                MV;
     typedef Epetra_Operator                   OP;
     typedef Belos::MultiVecTraits<ST,MV>     MVT;
     typedef Belos::OperatorTraits<ST,MV,OP>  OPT;

     using Teuchos::ParameterList;
     using Teuchos::RCP;
     using Teuchos::rcp;


     RCP<Epetra_Map> Map;//(new Epetra_Map(20, 0, Comm)); // LINK ERROR 
IF CONSTRUCTED WITH new Epetra_Map
     RCP<Epetra_CrsMatrix> A;
     RCP<Epetra_MultiVector> B, X;

     Epetra_Map m(200, 0, Comm); // RUNTIME ERROR

     if (rank == 0)
     {
         std::cout << "Communicator size " << Comm.NumProc() << std::endl;

         int willCrash = 1;

         switch (willCrash)
         {
             case 1:  // CRASH WITH MAP
                 std::cout << "MAP " << rank << " #global " << 
m.NumGlobalElements() << " #local " << m.NumMyElements() << std::endl;
                 break;

             case 2:  // CRASH WITH RCP
                 std::cout << "RCP " << rank << " #global " << 
Map->NumGlobalElements() << " #local " << Map->NumMyElements() << std::endl;
                 break;

             default: // NO CRASH
                 std::cout << rank << std::endl;
                 break;
         }
     }


#ifdef EPETRA_MPI
     MPI_Finalize();
#endif
     return 0;
}



The error at runtime is the following:

Why is Epetra_BlockMap::NumGlobalElements crashing? Am I doing something 
really stupid?

Any hint is highly appreciated!


Thanks!
