ippiResizeGetBufSize() error

Nick_T_1 — Fri, 09 Nov 2012 14:31:14 GMT

Hi Folks:

I am trying to use ResizeSqrPixel() function in Intel IPP, and I simply started with the example in the IPP manual, which is:

#ifdefOPENMP

#include <omp.h>

#endif

IppStatus ResizeSqrPixel( void )

{

Ipp32f src[12*12], dst[12*12];

IppiSize size = {12,12};

IppiRect srect = {0,0,12,12};

IppiRect drect = {0,0,6,6};

Ipp8u *buf;

int bufsize, nt;

IppStatus status = ippStsNoErr;

/* source image */

{

IppiSize roi = {12,12};

int i;

for( i=0; i<12; ++i ) {

ippiSet_32f_C1R( (Ipp32f)i, src+12*i+i, 12*sizeof(Ipp32f), roi );

--roi.width;

--roi.height;

}

/* calculation of work buffer size */

ippiResizeGetBufSize( srect, drect, 1, IPPI_INTER_SUPER, &bufsize );

#ifdefOPENMP

/* parallel algorithm */

#pragma omp parallel

{

#pragma omp master

{

/* number of threads */

nt = omp_get_num_threads();

/* memory allocate */

buf = ippsMalloc_8u( nt*bufsize );

}

#pragma omp barrier

{

/* thread's number */

int id = omp_get_thread_num();

/* ROI for one slice */

drect.y = (drect.height/nt)*id;

drect.height = (drect.height/nt)*(id+1);

if( NULL != buf )

status = ippiResizeSqrPixel_32f_C1R(

src, size, 12*sizeof(Ipp32f), srect,

dst, 6*sizeof(Ipp32f), drect,

0.5, 0.5, 0, 0, IPPI_INTER_SUPER, buf+id*bufsize );

}

#else

/* single algorithm */

{

/* memory allocate */

buf = ippsMalloc_8u( bufsize );

if( NULL != buf )

status = ippiResizeSqrPixel_32f_C1R(

src, size, 12*sizeof(Ipp32f), srect,

dst, 6*sizeof(Ipp32f), drect,

0.5, 0.5, 0, 0, IPPI_INTER_SUPER, buf );

}

#endif

/* memory free */

if( NULL != buf ) ippsFree( buf );

return status;

}

However, my compile could not succeed because of ippiResizeGetBufSize( srect, drect, 1, IPPI_INTER_SUPER, &bufsize ); and here is the error message:

>IntelIPPTest.obj : error LNK2019: unresolved external symbol _ippiResizeGetBufSize@44 referenced in function "enum IppStatus __cdecl ResizeTemplate(void)" (?ResizeTemplate@@YA?AW4IppStatus@@XZ)
1>C:\Users\ncui.THORLABS\Documents\Visual Studio 2008\Projects\IntelIPP\Debug\IntelIPP.exe : fatal error LNK1120: 1 unresolved externals

I am very confused since there seems no reason for this failure. I have included the ippi.h file, and I am using vs2008 on windows 7 32bit. Any one can please give some hint? Thanks a lot.

how did you link the example?

how did you link the example? it seems you need to add these libraries ippi.lib ipps.lib ippcore.lib to your linking line.

Hi Sergey: Thanks, I added libs you mentioned, it looks the project can be built now. But now issues came across: the project is builtable, but not excutable. If I click the green little triangle to "start debugging", a message box popped up and it says: The program can't start because ipps-7.0.dll is missing from your computer. Try reinstalling the program to fix this problem. I searched my entire computer, seems I don't have this ipps-7.0.dll.

Hi Nick,

Hi Nick, The IPP DLLs are installed as part of IPP on the system you're developing on. If you're trying to run on a non-development PC, then you will need to install the IPP redistributable package. Alternatively, you can just link against the IPP static libs and forget about the DLLs completely - this is the way I have IPP set up in my projects. Peter

Hi Peter: Thanks a lot for your reply, and I hope I understand it correctly: statically linking libraries will solve this problem. If so, how do I statically link the IPP libraries (*.lib files) when I am using VS2008 on a win 32 machine? Thanks a lot.

there 2 comments on this: 1.see the user's quide description about how you can link your application: http://software.intel.com/sites/products/documentation/doclib/ipp_sa/71/ipp_userguide_lnx/index.htm 2. since version 7.0, threaded static libraries (_t) are available as a separate download. You need to download it from registration center.

Thanks Federov, that helps.
