undefined reference to

[Tombat]

Hello,

-I try to install DCMTK 3.6 in code block (10.05)
-I used cmake -> compiler code block:mingw OK
-I gave in code block the paths. h (compiler) and for .cpp (linker) OK
-I did my little program.

Code: Select all

#include "chargementDicom.h"
#include "dcmtk/config/osconfig.h"
#include "dcmtk/dcmdata/dcfilefo.h"
#include "dcmtk/dcmdata/dcsequen.h"
#include "dcmtk/dcmdata/dcdatset.h"

#include <dirent.h>
#include <errno.h>
#include <iostream>
#include <fstream>
#include <string>
#include <vector>

using namespace std;


  void ChargementDicom::chargement(char* dossier)
  {
        std::vector<string> file_list;
        DIR *pdir;
        struct dirent *pfile;
        pdir = opendir(dossier);
        int ramirez=0;
            while ((pfile = readdir(pdir)) != NULL)
            {
               if(strcmp (pfile->d_name,".")==1 && strcmp (pfile->d_name,"..")==1)
            {
                string flName;
                flName.assign(dossier);
                flName += "/";
                flName += pfile->d_name;
                file_list.push_back(flName);
                ramirez++;
                //DebugLog <<"image "<<ramirez<<" : "<<pfile->d_name<<endl;
           }
            }
            closedir(pdir);

//chargement dicom
    for (int i = 0; i < ramirez; i++)


    {
        DcmFileFormat *fileformat = new DcmFileFormat();

        double largeur;
        const char * largeurchar;
        fileformat->loadFile(file_list[i].c_str(), EXS_Unknown, EGL_noChange, DCM_MaxReadLength,ERM_autoDetect);
        DcmElement *element;
        fileformat->loadAllDataIntoMemory();
        fileformat->getDataset()->findAndGetString (DcmTagKey(0x0028,0x0010),largeurchar,true);
        char * pEnd2;
        largeur = strtod (largeurchar,&pEnd2);
    }
  }

But i have the following message:

Code: Select all

...
obj\Debug\ChargementDicom.o||In function `_ZN15ChargementDicom10chargementEPc':|

--> in the other topics, i saw that it's a Bad link??

I am an absolute beginner
how I should do to generate links in CB

Thanks in advance.

Hi Tom,

you have to link the corresponding DCMTK libraries to your executable. That is, when linking you have to speficy at least options like "-ldcmdata -loflog -lofstd -L/path/to/DCMTKinstall/lib".

On Windows, adapt the path in the statement to backslashes, e.g. '-L"c:\path\to\DCMTKinstall\lib".

Best regards,
Michael
