I'm trying to link dcmtk libraries for developing application for DICOM images. However, I cannot link those external libraries - I get the error message:

C:\Users\Donn\Documents\untitled1\main.cpp:10: error: undefined reference to `DicomImage:icomImage(char const*, unsigned long, unsigned long, unsigned long)'
main.cpp:

Qt Code: 
  1. #include "dcmtk/config/osconfig.h"
  2. #include "dcmtk/dcmdata/dctk.h"
  3. #include "dcmtk/dcmimgle/dcmimage.h"
  4. #include "iostream"
  5.  
  6. int main(int argc, char *argv[])
  7. {

  9.     DicomImage *image = new DicomImage("test.dcm");
  10.     if (image != NULL){
  11.         std::cout << "hell yeah!";
  12.     }

  14.     return 0;

How to fix this problem? I even tried to delete the LIBS line and still I get the same effect. Looks like those libraries are not linked at all.
