[Insight-users] Re: Reading and writing image files using ITK and Cmake

[Matt Kelsey]

Hello KPatra,
I think you will find that your message is due to the code on lines 59
- 68 in ImageReadWrite.cxx, i.e.
int main( int argc, char ** argv )
{
  // Verify the number of parameters in the command line
  if( argc < 3 )
    {
    std::cerr << "Usage: " << std::endl;
    std::cerr << argv[0] << " inputImageFile  outputImageFile " << std::endl;
    return EXIT_FAILURE;
    }

whereas the program checks that you have provided input and output
file name.  In your example you are providing these statically.  You
can either remove the code above requiring argc>=3 or just provide
your image file name as command line parameters with the original
example code.  Good luck.

Matt
