将DCMTK与Visual Studio一起使用时，链接器错误LNK2019

Question

This is not a new question but the solutions haven't worked for me. I want to read dicom files using C++. I have 32-bit Windows PC with VS 2013 community edition.

This post and other answers therein suggested using DCMTK. I installed DCMTK (using CMake followed by VS) and configured it for use with VS using guidelines and links provided in this post . Then I wrote a simple test program and tried to compile it:

#include "stdafx.h"
#include "dcmtk\dcmdata\dctk.h"
#include "dcmtk\config\osconfig.h"
#include "dcmtk\dcmimgle\dcmimage.h"
#include <iostream>
using namespace std;

int main()
{
    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
            cerr << "Error: cannot load DICOM image (" << DicomImage::getString(image->getStatus()) << ")" << endl;
    }
    delete image; 
    return 0;
}

Upon compilation, it gives the following error:

dcmdata.lib(dcuid.obj) : error LNK2019: unresolved external symbol _Netbios@4 referenced in function "unsigned char * __cdecl getMACAddress(unsigned char * const)" (?getMACAddress@@YAPAEQAE@Z)

This error seems to be common but none of the following solutions work for me:

1. FAQ#27 and another post of DCMTK forum: It suggests using particular order of lib files to be included. My order of including files is as follows (I tried the reverse order as well but it didn't work):

   

All of this doesn't work. In fact, I'm not sure which lib files are supposed to be included? How to decide that?

I've also included "C:\\Program Files\\DCMTK\\lib" under additional library directories and "C:\\Program Files\\DCMTK\\include" under additional include directories in project properties.

2. Another similar question at stackoverflow has not been answered. Comments suggest to re-run CMake by disabling DCMTK_OVERWRITE_WIN32_COMPILER_FLAGS. I didn't do it because the DCMTK help page says don't disable this unless you really know what you're doing.

Can someone please guide?

Answer 1

NetBios函数驻留在NETAPI32.LIB中，因此您可以尝试将NetAPI32.lib（位于列表中）移动到该列表的顶部。

Answer 2

Not sure which version of the DCMTK you use, but for the current development snapshot you need the following standard libraries (on Windows): "ws2_32 netapi32 wsock32". This information can be found in DCMTK's CMake files. By the way, you don't seem to use CMake for your project, right?

Answer 3

I think you misspelled dcmsign.lib as dcmsig.lib.

If changing that doesn't fix it, I would suggest the following order based on the support page that you linked to: NetAPI32.lib WSock32.lib ofstd.lib oflog.lib dcmdata.lib dcmsign.lib dcmnet.lib dcmsr.lib dcmqrdb.lib dcmtls.lib dcmwlm.lib dcmimgle.lib dcmpstat.lib dcmjpls.lib dcmjpeg.lib dcmimage.lib ijg16.lib ijg12.lib ijg8.lib

I think that in this list, each library has to come after all the libraries that it depends on.

Answer 4

检查你的.lib和vs平台是否相同，例如x64的lib，那么你的vs平台必须是x64。

Answer 5

I had the same error. You can go to project properties-> linker -> input -> Additional Dependencies-> Edit -> add these two libraries-( netapi32.lib,wsock32.lib) before all other libraries . This solved the error for me .
