[Insight-users] dllimport error gdcm under visual studio...

[Neil.Burdett at csiro.au]

Hi Luis,
         yes I have ITKIO in my Cmakelist.txt file, and in visual studio linker options I can see for example one of the libraries being itkgdcm.lib.

B) I'm using the gdcm that comes as part of itk 3.12 (as that's what we have on our Ubuntu build)

I have a workaround that enables my code to built. I basically remove the "GDCM_EXPORT" macro from C:\src-itk-3.12.0\Utilities\gdcm\src\gdcmDicomDir.h file so it looks like this now; "class DicomDir: public Document"

Not a very elegant solution as I was hoping it would work without any changes...

Cheers
Neil

Hi Neil,

A) Are you adding "ITKIO" to the list of libraries to link with ?
     That should bring in "gdcm"

B) Are you using a "system gdcm" or the one that comes with ITK ?


Please let us know,

      Thanks

          Luis
