[Insight-users] Re: Help on link error with a template function

[Ritesh Bafna]

Hi Sam,

You need to call your function in this way :

myPyramid<InputArray2D, FloatArray2D >( inputImageArray2D,  
outputImageArray2D, (unsigned
int)lWidth, (unsigned int)lHeight ) ;

Dear ITK developers and users;



I defined a template function:



template<class InputArrayType, class OutputArrayType>

void myPyramid(itk::Array2D< InputArrayType > in, itk::Array2D<
OutputArrayType > out, unsigned int nColumns, unsigned int nRows) ;



and used it in the main file:



        typedef signed short InputPixelType;



typedef       itk::Array2D< InputPixelType > InputArray2D ;

        InputArray2D  inputImageArray2D( lWidth, lHeight ) ;



        typedef       itk::Array2D< float > FloatArray2D ;

        FloatArray2D  outputImageArray2D( lWidth/2, lHeight/2 ) ;



        myPyramid( inputImageArray2D, outputImageArray2D, (unsigned
int)lWidth, (unsigned int)lHeight ) ;



but a link error displays:



DicomImageReadWrite.obj : error LNK2019: unresolved external symbol "void
__cdecl myPyramid(class itk::Array2D<short>,class
itk::Array2D<float>,unsigned int,unsigned int)"
(?myPyramid@@YAXV?$Array2D at F@itk@@V?$Array2D at M@2 at II@Z) referenced in
function _main



Debug\DicomImageReadWrite.exe : fatal error LNK1120: 1 unresolved externals



Would you please help me to find where the problem is and how to fix it?
Your kind help is greatly appreciated.



Best regards,

Sam
