Error with dim_vector

[Justin Bare]

The following C++ code gives me the runtime error "undefined symbol:
_Z4data10dim_vector" at the line "data(dim_vector(v)) =
Cell((octave_value)var);" Any ideas?

    int numVars = myData.arrayVars.size();

    string_vector names;
    names.resize(numVars);
    for(int i = 0; i < numVars; i++){
      names[i] = myData.varNames[i];

    }


    int numTimeSteps = myData.arrayVars[names[0]].size();

    Cell data(dim_vector(numVars));


    for(int v = 0; v < numVars; v++){
      int dataLength = myData.arrayVars[names[v]][0].size();

      NDArray var = NDArray(dim_vector(numTimeSteps, dataLength));
      for (int t = 0; t < numTimeSteps; t++){
        for(int i = 0; i < dataLength; i++){
          var(t, i) = myData.arrayVars[names[v]][t][i];

        }
      }
      data(dim_vector(v)) = Cell((octave_value)var);
    }


Thanks for the help
