error LNK2001: unresolved external symbol _ippsGetLibVersion@0

i'm having:
error LNK2001: unresolved external symbol _ippsGetLibVersion@0
with my MS VS2005, although i have already included the ippcore.h in my project and linked to ippcore.lib?

You need to add ipps library to your linker settings. You also might be interested to see IPP samples, which demostrate how to use IPP functions in many areas.

i did 'ippcore.lib' add in Linker->Command line->additional options?

[Vladimir_Dudnik]

Please add ipps.lib as well.

[Vladimir_Dudnik]

By the way, it is easy to learn which functions correspond to which library by looking through IPP header files. For example, ippGetCpuClock function is declared in ippcore.h and so it contained in ippcore.lib library (ippcorel.lib for static library) whereas function ippsZero_8u is declared in ipps.h and is implemented in ipps.lib file (ippsmerged.lib/ippsemerged.lib for static libraries)
