[Insight-users] errors about output with files

[李健]

Dear all:

 

In itk examples, sometimes the program use std::ofstream to output the results to a file. For example:

 

  if( argc > 9 )
    {
    std::ofstream parametersFile;
    parametersFile.open( argv[9] );
    parametersFile << finalParameters << std::endl;
    parametersFile.close();
    }

 

When I use the same code, however, there is an error information: 

 

error: aggregate 'std::ofstream parametersFile' has incomplete type and cannot be defined.

 

How should I solve this problem?

 

Thanks a lot.
