[Insight-users] (update) how to create ITK dll with visual c++ 6.0?

[Haris Saybasili]

Hi,

I tried cmake, it created the project. However, Visual C++ couldn't compile
it. I had 44 errors, all of which was unresolved references. I added
additional lib and include libraries to the project, but no luck. I exported
the makefile, and edited it. I get the same error as always:

I had searched the net, and saw that these kind of errors are very common to
vc++ 6.0. Is there anybody who succeded in creating an ITK DLL with msvc++
6.0?

I am new to windows application development (I use linux normally), so maybe
I made a very elemental error.

Thanks,

haris

PS: And for the DLL part, my code was like this:

----------------
1. myitk.h:
----------------

#ifndef __HELLO_H
#define __HELLO_H
#ifndef __HELLO__
#define __HELLOLIB__ __declspec(dllimport)
#else
#define __HELLOLIB__ __declspec(dllexport)
#endif
__HELLOLIB__ int myitkhello() ;
#endif

#include "C:\ITK\src\Code\Common\itkWin32Header.h"
#include "itkImage.h"


class myitk
{
  public:

      myitk();

      ~myitk();

};

----------------
myitk.cpp:
----------------

#define __HELLO__
#include "myitk.h"

myitk::myitk() {


    typedef itk::Image< unsigned short, 3 > ImageType;

    ImageType::Pointer image = ImageType::New();
    std::cout << "ITK Hello World !" << std::endl;
    FILE *f;
    f = fopen("c:/temp/itk.txt","w");
    fprintf(f,"itk : hello world!!!\n");
    fclose(f);

}


myitk::~myitk()
{

}

__HELLOLIB__ int myitkhello() {

    myitk mtk();
    return 0;
}
