Linker Warning

[dwinfield]

I'm staic linking and recived the following warning using VS2008

warning LNK4248: unresolved typeref token (01000015) for 'MomentState64f'; image may not run

Any ideas? The code does seem to run as well as the moment commands.

THANKS

It seems you missed some of IPPlibrary in link options. Please check you link with ippcore library

Hi Vladmir,
I do have ippcore linked in and still get that warning.
THANKS

I never seen that problem with IPP. Might be something is wrong in project settings? And by the way, what version of IPP do you use?

Hi dwindield!

This error mean that you try to use struct MomentState64f directly not by IPP functions. It isn't corret, you have to use IPP functions only!

From Microsoft MSDN:

The following sample generates LNK4248. Define struct A to resolve.

Copy Code
// LNK4248.cpp
// compile with: /clr /W1
// LNK4248 expected
struct A;
void Test(A*){}

int main() {
Test(0);
}

This is interesting --> I'm using the later version of IPP. Here's the only part where I use the structure"

IppiMomentState_64f* pState;
IppiSize Small;
IppiPoint pointROI = {0,0};
int ROIoffset;
Small.width = m_sc_Blobs.m_Info.rect.width;
Small.height = m_sc_Blobs.m_Info.rect.height;
ROIoffset = m_sc_width*( m_sc_Blobs.m_Info.rect.y) + ( m_sc_Blobs.m_Info.rect.x);
m_Status = ippiMomentInitAlloc_64f( &pState, ippAlgHintNone );
m_StatusString = ippGetStatusString( m_Status );
m_Status = ippiMoments64f_8u_C1R(m_sc_AnalyzedImage+ROIoffset, m_sc_width, Small, pState );
m_StatusString = ippGetStatusString( m_Status );
m_Status = ippiGetSpatialMoment_64f( pState, 0, 0, 0, pointROI, &m_sc_Blobs.m_mom0 );
m_StatusString = ippGetStatusString( m_Status );
m_Status = ippiGetSpatialMoment_64f( pState, 1, 0, 0, pointROI, &m_sc_Blobs.m_momx );
m_StatusString = ippGetStatusString( m_Status );
m_sc_Blobs.m_cgx = m_sc_Blobs.m_momx / m_sc_Blobs.m_mom0;
m_sc_Blobs.m_cgx += (m_sc_Blobs.m_Info.rect.x);
m_Status = ippiGetSpatialMoment_64f( pState, 0, 1, 0, pointROI, &m_sc_Blobs.m_momy );
m_StatusString = ippGetStatusString( m_Status );
m_sc_Blobs.m_cgy = m_sc_Blobs.m_momy / m_sc_Blobs.m_mom0;
m_sc_Blobs.m_cgy += (m_sc_Blobs.m_Info.rect.y);
m_Status = ippiGetCentralMoment_64f(pState,2,0,0,&m_sc_Blobs.m_moix);
m_Status = ippiGetCentralMoment_64f(pState,0,2,0,&m_sc_Blobs.m_moiy);
m_Status = ippiGetCentralMoment_64f(pState,1,1,0,&m_sc_Blobs.m_moixy);
ippiMomentFree_64f(pState);

Hi!

Probably not. I've created the simple example according your text:

#include "ipp.h"

int main()
{
IppiMomentState_64f* pState;
IppStatus m_Status;
Ipp64f pValue;
const Ipp8u* pSrc;
const char* m_StatusString;
IppiSize Small;
IppiPoint pointROI = {1,1};
int ROIoffset;
Small.width = 1;
Small.height = 1;
m_Status = ippiMomentInitAlloc_64f( &pState, ippAlgHintNone );
m_StatusString = ippGetStatusString( m_Status );
m_Status = ippiMoments64f_8u_C1R(pSrc, 1, Small, pState );
m_StatusString = ippGetStatusString( m_Status );
m_Status = ippiGetSpatialMoment_64f( pState, 0, 0, 0, pointROI, &pValue );
m_StatusString = ippGetStatusString( m_Status );
m_Status = ippiGetSpatialMoment_64f( pState, 1, 0, 0, pointROI, &pValue );
m_StatusString = ippGetStatusString( m_Status );
m_Status = ippiGetSpatialMoment_64f( pState, 0, 1, 0, pointROI, &pValue );
m_StatusString = ippGetStatusString( m_Status );
m_Status = ippiGetCentralMoment_64f(pState,2,0,0,&pValue);
m_Status = ippiGetCentralMoment_64f(pState,0,2,0,&pValue);
m_Status = ippiGetCentralMoment_64f(pState,1,1,0,&pValue);
ippiMomentFree_64f(pState);
}

and no problem:
