My goal is open Dicom files and convert thes into cv::Mat to process them with Opencv.
I have compiled dcmtk 3.6.3 on ubuntu 18.4.1 and tried to link it with Qt 5.11.1 with Qt Creator 4.6.2 but failed to do so.
# pro file
QT += core
QT -= gui
TARGET = DcmtkTesting
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
DCMTK_PREFIX = "/home/ismail/dcmtk363"
DCMTK_LIBS_PREFIX=$$DCMTK_PREFIX"/lib"
DCMTK_INCLUDE=$$DCMTK_PREFIX"/include"
INCLUDEPATH+=$$DCMTK_INCLUDE
LIBS += -L$$DCMTK_LIBS_PREFIX
SOURCES += main.cpp
and for the main: #include
#include "dcmtk/config/osconfig.h"
#include "dcmtk/dcmdata/dctk.h"
#include <dcmtk/dcmimgle/dcmimage.h>
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
DicomImage *image = new DicomImage("test.dcm");
if (image != NULL)
{
if (image->getStatus() == EIS_Normal)
{
if (image->isMonochrome())
{
image->setMinMaxWindow();
Uint8 *pixelData = (Uint8 *)(image->getOutputData(8 /* bits*/));
if (pixelData != NULL)
{
/* do something useful with the pixel data */
}
}
} else
cout << "Error: cannot load DICOM image (" << DicomImage::getString(image->getStatus()) << ")" << endl;
}
delete image;
return a.exec();
}
and I got this errors:
The error indicates that the linker could not find the symbols (methods) provided by the library. In your .pro
file, you pointed the linker to a directory where your library is located, but you forgot to specify which library should be linked.
So you have to modify the line LIBS +=...
accordingly, e.g.:
LIBS += -L$$DCMTK_LIBS_PREFIX -ldcmtk
Since I don't know the actual name of the library, I use dcmtk
in my example. You may have to adopt it to fit your build environment. Just make sure that you have the -l
(lower case L
), immediately followed by the library name.
