Thank you. Now I have this FPC command line (added -Xe):

D:\Programy\Lazarus\fpc\2.6.4\bin\i386-win32\fpc.exe -B -MObjFPC -Scghi 
-O1 -g -gl -XX -l -vewnhibq -FiD:\TEMP\zmazma\lib\i386-win32 
-FlD:\TEMP\zmazma\Intel_IPP -FuD:\TEMP\zmazma\ 
-FUD:\TEMP\zmazma\lib\i386-win32\ -Xe test_IPP.lpr

But I still get :
   Error: Invalid DLL .\Intel_IPP\ippcoremt.lib, Dos Header invalid

When I have removed from source code {$linklib} and use this command line:
(added: -k--library -k:ippcoremt.lib -k--library-path 
-kD:\TEMP\zmazma\Intel_IPP)

D:\Programy\Lazarus\fpc\2.6.4\bin\i386-win32\fpc.exe -B -MObjFPC -Scghi 
-O1 -g -gl -k--library -k:ippcoremt.lib -k--library-path 
-kD:\TEMP\zmazma\Intel_IPP -vewnhibq -FiD:\TEMP\zmazma\lib\i386-win32 
-FlD:\TEMP\zmazma\Intel_IPP -FuD:\TEMP\zmazma\ 
-FUD:\TEMP\zmazma\lib\i386-win32\ -Xe test_IPP.lpr

Then I get:
   test_IPP.lpr(17,1) Error: undefined reference to `ippGetLibVersion'
(I have tried also: _ippGetLibVersion, _ippGetLibVersion at 0 ...)
