c++ - Using gdcm libs in UE4 -


for ue4 project want use gdcm libraries c++ load ct scans. tried lot last few days i'm still not able use gdcm... error? can me?

  • i created dll , lib files cmake (vs 2013 win64) successfully.
  • i put libs in ...unreal projects\volumeimport\thirdparty\includes\gdcm\libraries
  • i added each of 16 libs in volumeimport.build.cs publicadditionallibraries.add(path.combine(librariespath, "gdcmmsff.lib")); publicadditionallibraries.add(path.combine(librariespath, "gdcmcommon.lib")); ...
  • i put header files in unreal projects\volumeimport\thirdparty\includes\gdcm\includes
  • i set includepath location in project properties.
  • i put dlls in c:\windows\system32

then used headers:

#include "volumeimport.h"  #include <gdcmversion.h> #include <gdcmreader.h> #include <gdcmpixmapreader.h> #include <gdcmimagereader.h> #include <gdcmattributes.h>  bool ctfileloader::convert_dicom() {     /** ... other working code ... */      gdcm::trace::setdebug(false); gdcm::trace::seterror(true);      gdcm::imagereader reader;     reader.setfilename(files_to_process[i].c_str());      if(!reader.read()) { }  }

and error in gdcmmediastorage.h: "error c4515: 'gdcm': namespace uses itself."

i tried using different includes causes diffrent errors in diffrent headers... there wrong libraries? i'm sure added, because using gdcmtrace.h , gdcm::trace::functions works fine.

now got solution:

  • in volumeimport.build.cs additionally added dlls: publicdelayloaddlls.add(path.combine(librariespath, "gdcmmsff.dll")); ...
  • i changed gdcmmediastorage.h file: comment out "using namespace gdcm;"
  • furthermore had dynamic_cast problems big library , needs enable rtti
