I would recommend using the DCMSCU Class
Here is a simplified pseudocode
DcmSCU *SCU = new DcmSCU (this);
OFList<OFString> XferSyntaxes;

if (SCU != NULL)
{
SCU ->setPeerAETitle(PeerAETitle);
SCU ->setPeerHostName(PeerHostName);
SCU ->setPeerPort(PeerPortNumber);
// Add Preferred Outgoing Transfer Syntaxes
XferSyntaxes.push_back (UID_LittleEndianImplicitTransferSyntax);
XferSyntaxes.push_back(UID_LittleEndianExplicitTransferSyntax);
.....
.....
// Add Presentation Context for each required SOP Class UID
SCU ->addPresentationContext(SOPClassUID, XferSyntaxes);
.....
.....
status = SCU ->initNetwork();
status=SCU->negotiateAssociation();
const T_ASC_PresentationContextID presID = SCU->findPresentationContextID(AbstractSyntax,TransferSyntax);
//Send Request on a presentation context ID
...
...

//Close Association
SCU->closeAssociation();
}

However, I would recommend using the DCMSCU Class
SCU = new DcmSCU (this);

if (SCU != NULL)
{
SCU ->setPeerAETitle(PeerAETitle);
SCU ->setPeerHostName(PeerHostName);
SCU ->setPeerPort(PeerPortNumber);
SCU ->addPresentationContexts(PreferredOutgoingSyntax);
status = SCU ->initNetwork();
status=SCU->negotiateAssociation();
SCU->findPresentationContext(..,..)
//Send Request
...
...

//Close Association
SCU->closeAssociation();
}

Hope that helps.
I face a problem while use DCMTK which is

/Users/abduljaleelmalik/full-dcmtk/include/dcmtk/ofstd/ofstream.h:80:0 /Users/abduljaleelmalik/full-dcmtk/include/dcmtk/ofstd/ofstream.h:80:2: error: #error DCMTK needs stringstream or strstream type


#define INCLUDE_CSTDIO
#include "dcmtk/ofstd/ofstdinc.h"
#include <dcmtk/dcmimgle/dcmimage.h>
#include <dcmtk/config/osconfig.h>
#include <dcmtk/dcmimgle/dcmimage.h>

how can I override that

First of all, you should include osconfig.h at the top of all other included files. So, your code should look like

#define INCLUDE_CSTDIO
#include <dcmtk/config/osconfig.h>
...
...

Hi,

try to add "-DHAVE_CONFIG_H" to your compiler flags, otherwise including osconfig.h does actually nothing.

Best regards,
Michael

how can I do that in xcode , there're no direct compiler flag

there're
OpenMP linker flags
other linker flags
symbol ordering flags
warning linker flag

I tried add it to other linker flags , but the same error appeared

I tried also to add

#undef verifty
#define INCLUDE_CSTDIO
#include <dcmtk/config/osconfig.h>
#include <dcmtk/dcmimgle/dcmimage.h>

but the error /DCMTK_BINARY/include/dcmtk/ofstd/ofstream.h:80:0 /DCMTK_BINARY/include/dcmtk/ofstd/ofstream.h:80:2: error: #error DCMTK needs stringstream or strstream type

still appear in ofstream.h

#include <iostream.h>
#include <fstream.h>
// For old STREAMS library: preference for strstream
#if defined(HAVE_STRSTREA_H) || defined(HAVE_STRSTREAM_H)
#ifdef HAVE_STRSTREA_H
#include <strstrea.h>
#else
#include <strstream.h>
#endif
#elif defined(HAVE_SSTREAM_H)
#include <sstream.h>
#define USE_STRINGSTREAM
#else
#error DCMTK needs stringstream or strstream type
#endif
#include <iomanip.h>

Hi,

It is not a Linker flag, it is a compiler flag. First, every .cc file is compiled into an object file, then in the end, they are linked together into applications. You can recognize an application if one of the objects (and only one) contains a main() function.

I do not have a mac here, but there will surely be change to change the compile flags, not only the linker flags. Just right-click on file to be compiled, and look for compiler or build flags. Maybe again, google may help.

This is not a dcmtk-related problem.

Best regards,
Michael

Right, and I said you would to do (add a compile flag); the rest is now up to you: learning how to do that with your compiler (Xcode/gcc).

Hi,

Omar's code snippet was just fine. If you need a full example, look might look at the demo SCU from the CTK project.

Good luck,
Michael

Hi,

have a look at the dcmdata online documentation.
