You should really direct your GDCM question to the GDCM ML, see FAQ:

Did you check dirname ends with a trailing '/' character ?

SetDirectoryName is a specific API only found in vtkDICOMImageReader.
It did not make any sense when implementing vtkGDCMImageReader, thus
only vtkGDCMImageReader::SetFileNames is implemented.

No you don't. At least this is impossible from the code you sent.

You are not sending the actual piece of code that is generating this error.
