DCMTK and QT problems

[Polielia]

Hi, i'm trying to make a program in Qt that take visualize a image in a QLabel and then I do things with the image.
i have write the code and create the GUI and it works fine for jpeg file. But I have to visualize images from dcm format so now I have to add some code for manage the dcm format.

I have read a lot of guide but I'm not able to use the DCMTK libraries.
I've done:
+download dcmtk-3.6.0;
+download cmake-3.8.0-rc1-win64-x64;
+use cmake and configure the project for visual studio 14;
+In the Qt .pro file i've add the code:

Code: Select all

INCLUDEPATH += C:/Users/.../DCMTK/include

LIBS += -L C:/Users/.../DCMTK/lib \
-ladvapi32 \
-ldcmdata \
-loflog \
-lofstd \
-lws2_32 \
-lnetapi32 \
-lwsock32

I found on web this, is right ?

when i go to my mainwindows i can add the libraries and if I write some code it is recognize from the editor (the color of the words change) but when i try to run I have these errors:

Code: Select all

C:\Users\...\DCMTK\include\dcmtk\ofstd\offile.h:200: error: cannot convert 'bool' to 'FILE* {aka _iobuf*}' in assignment
     file_ = _popen(command, modes);

C:\Users\...\DCMTK\include\dcmtk\ofstd\offile.h:262: error: no matching function for call to 'OFFile::_pclose(FILE*&)'
         result = _pclose(file_);

and I can't make any kind of test because every code I write give the same errors.
I use:
- windows 10
- Qt 5.1.1 MinGW 32bit

what I'm doing wrog?

Perhaps try a more recent snapshot, I can somewhat remember that there was a problem with _popen etc. being a #define in MinGW, that I fixed by adding brakets to prevent macro expansion. Also, why do you use MinGW but setup the project for Visual Studio?

Also, why do you use MinGW but setup the project for Visual Studio?

I have setup the project for visual studio because with MinGW i had some errors, do you think that if I use the VS compiler in Qt should be better?

being a #define in MinGW, that I fixed by adding brakets to prevent macro expansion

Can you explain me better this? because the line error are:
Line 200 in offile.h:

Code: Select all

196  OFBool popen(const char *command, const char *modes)
197  {
198    if (file_) fclose();
199  #ifdef _WIN32
200    file_ = _popen(command, modes);
201 #else
202    file_ = :: popen(command, modes);
203 #endif
204    if (file_) popened_ = OFTrue; else storeLastError();
205    return (file_ != NULL);
  }

Line 262 in offile.h

Code: Select all

254  int fclose()
255  {
256    int result = 0;
257    if (file_)
258    {
259      if (popened_)
260      {
261#ifdef _WIN32
262        result = _pclose(file_);
263#else
264        result = :: pclose(file_);

It seems my memory was wrong, however, this should be the fix for your problem.

Thanks, now i'm able to use the library.
Now I want to visualize a DICOM image into a QLabel.
I have already write the code for a jpg image using QPixmap and visualize it using SetPixmap for the Label. so how can I do this with the DICOM image?

Code: Select all

QString Imagename = QFileDialog::getOpenFileName(this,tr("Open Image ), "", DICOM(*.dcm)"));  //get the image to open

DicomImage *Dimage = new DicomImage (Imagename); // Imagename is a QString, how can combine it with this function that need a char? also if i write a normal name like ("test.dcm") i got an error                                            undefined reference to `DicomImage::DicomImage(char const*, unsigned long, unsigned long, unsigned long)'
Uint8 *pixeldata = (Uint8*) (Dimage->getOutputData(8)); // can I use this data for visualize the image in the QLabel?
