Then I get:

I've downloaded the IPP libs and did some tests to make sure that static
linking is possible.
The working declaration is:
{$L ippcoremt.lib}
function ippGetLibVersion: PIppLibraryVersion; cdecl; external name
'ippGetLibVersion@0';
You need to use the external linker via the -Xe option, since internal
linker does not support static libraries. Only single object files can
be linked.
ippGetLibVersion@0 - is the C++ mangled name used by MS VC++. FPC
supports then "cppdecl" calling convention, but only for the GCC
compiler, which uses different name mangling algorithm. So you need to
use cdecl and manually specify the name. Function names can be found
using "objdump -t ippcoremt.lib". You should specify the name without
the "_" prefix. It is added automatically when cdecl is used.
