linking dcmtk to existing visual Studio 6.0 project

[Christof Fleischmann]

Maybe stupid question.
I try to link dcmtk library to an existing C++ project (Visual Studio 6.0)

Just as example:
I place

#include "dcddirif.h"

test::testfunction()
{
DicomDirInterface MyDicomDirInterface;
}

into my code and add
dcmdata.lib (Objekt-Bibiliothek_Module)
to the Linker list


Now I get following linker error. So it seems that dcmdata.lib has already statically linked MSVC... dlls. What I am doing wrong?

With best regards Christof

Hmm... I thought this was already covered in the FAQ, but it seems not to.
The problem is that Visual C++ comes with two different, incompatible iostream libraries, and you have to compile all parts of your project consistently with one or the other. It seems that you are mixing the two libraries here.
Try removing the line "#define USE_STD_CXX_INCLUDES" in config/include/cfwin32.h, recompile the complete DCMTK and compile and link your project again.
