unresolved external symbol DcmFileFormat()

[quyps]

Hi all!

I have a problem when i use dcmtk 3.5.4, it is built correctly by both VS6
and VS2008. But when i try to use load a DCM file using DcmFileFormat as following:

CFileDialog oFileDlg(TRUE, NULL, NULL, OFN_OVERWRITEPROMPT, "DCM Files (*.dcm)|*.dcm|");
if(oFileDlg.DoModal() == IDOK)
{
CString str = oFileDlg.GetPathName();
DcmFileFormat *dfile = new DcmFileFormat();

OFCondition cond = dfile->loadFile(str, EXS_Unknown,EGL_withoutGL,DCM_MaxReadLength,ERM_autoDetect);
if(cond.bad())
{
AfxMessageBox(cond.text());
}
}

i got this link error:
Linking...
DCMLoad6Dlg.obj : error LNK2001: unresolved external symbol "public: __thiscall DcmFileFormat::DcmFileFormat(void)" (??0DcmFileFormat@@QAE@XZ)
Debug/DCMLoad6.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

i check all include files and lib carefully but it seem not be caused by this. This problem occur in both case that dcmtk is built by VS6 and VS2008.

i need your help! thanks!

by the way, do you know any tutorial about programming with dcmtk or examples code ?

Did you read and check FAQ #27?

There are numerous examples in the "apps" subfolders of the source code package.

What's wrong here?

i installed both vs2008 and vs6 on my computer, i use vs6 to compile dcmtk and my program

Hi Marco! i solved it.
Thank you very much!

Hi !

I try to load a .dcm file by following code:

Code: Select all

	if(oFileDlg.DoModal() == IDOK)
	{
		CString str = oFileDlg.GetPathName();
		DcmFileFormat *dfile = new DcmFileFormat();
		
		char* pz = (char*)str.GetBuffer(0);
	
		OFCondition cond = dfile->loadFile(str, EXS_Unknown,EGL_withoutGL,DCM_MaxReadLength,ERM_autoDetect);
				if(cond.bad())
				{
					AfxMessageBox(cond.text());
				}
		
		E_TransferSyntax xfer = dfile->getDataset()->getOriginalXfer();
		 unsigned long       opt_compatibilityMode = CIF_MayDetachPixelData | CIF_TakeOverExternalDataset;
		DicomImage *di = new DicomImage(dfile, xfer,  opt_compatibilityMode, 0, 1);

		
		if (di->getStatus() != EIS_Normal)
			AfxMessageBox(DicomImage::getString(di->getStatus()));
		
		di->writeBMP(".\\from_dicom.bmp",24);
	
	}

but di->getStatus() always return EIS_NotSupportedValue
i try to test my image with dcm2pnm.exe with command
dcm2pnm +obt "CT_test.dcm" "D:\test.bmp"
it run correctly, i also tried to debug dcm2pnm project in dcmtk source and set all parameters exactly same as my code, it's OK.

What's wrong here?

Thanks
