I get the following linker errors (VS 2010) for the functions ippsln_32f and ippsexp_32f using the static, single-threaded (ipps_l.lib) Ipp 7.1.1 libraries:

(psexp32f_m7---ippsExp_32f_I.obj) : error LNK2019: unresolved external symbol m7_ippsExp_32f_A21 referenced in function m7_ippsExp_32f_I

The same errors appear for ippsln_32f

This worked fine with ipp 7.0.  Is this a known issue or is there a work around to this problem?

It looks similar to:

Forum topic: Static Linking Error - ippcore-7.1 Dependency
Web-link: http://software.intel.com/en-us/forums/topic/328164

and please take a look.

I believe it is related - but doesn't appear to be quite the same thing.  We are not using the Intel compiler (as the poster is) - just the VS 2010 compiler with the single-threaded static IPP libraries.  However, the dependency is still there for those 2 functions (ippsln_32f, ippsexp_32f) - the static library does not contain their dependencies, hence you cannot link.  I believe this should be very easy to replicate (attempt to link any code referencing ippsln_32f using only the single-threaded static library (ipps_l.lib, ippcore_l.lib).  The problem is evident in both 32- and 64-bit builds.

Notably, linking to ipps.lib does not resolve the problem either, so I believe it something actually missing from ipps_l.lib.

Sorry for my wrong assumption.
