including ipp libraries

[Oleg_M_2]

Hello!

I'm trying to use Intel IPP for signal processing. I began the work with the Add functions (ippsAdd_64f_A53 and ippsAdd_64f). I included ippvm.h, ippcore.h and ipps.h and wrote the CMakeLists.txt file as follows:

cmake_minimum_required(VERSION 3.7)
project(Test)
find_library(IPP_CORE libippcore.a PATHS /opt/intel/ipp/lib/intel64)
find_library(IPP_VM libippvm.a PATHS /opt/intel/ipp/lib/intel64)
find_library(IPP_S libipps.a PATHS /opt/intel/ipp/lib/intel64)
add_executable(Test main.cpp)
target_include_directories(Test PRIVATE /opt/intel/ipp/include)
target_link_libraries(Test ${IPP_CORE} ${IPP_VM} ${IPP_S})

The first of the function (_A53) works well, but while using the second one I get the following error:

/opt/intel/ipp/lib/intel64/libipps.a(jmp_ippsAdd_64f.o): In function 'in_ippsAdd_64f':
jmp_ippsAdd_64f.c:(.text+0x1): undefined reference to 'ippSafeInit'
/opt/intel/ipp/lib/intel64/libipps.a(jmp_ippsAdd_64f.o): In function 'ippsAdd_64f':
jmp_ippsAdd_64f.c:(.text+0x2a): undefined reference to 'ippJumpIndexForMergedLibs'

Tell me please, what is wrong? As I understand, I need to link some more libraries, but which of them?

Thanks in advance.

+ ipps.a

Sorry, but as I understand you recomend including libipps.a. But I've already included it with:

find_library(IPP_S libipps.a PATHS /opt/intel/ipp/lib/intel64)
...
target_link_libraries(Test ${IPP_CORE} ${IPP_VM} ${IPP_S})

Could you, please explain my mistake?

[Gennady_F_Intel]

sorry, I missed that you added ipps.a lib, then at the first galnce everything looks correct.  Could you try to link this case explicitly w/o Cmake?

Hello,

Try to change the order of the libraries in "target_link_libraries" statement. First IPPS, then IPPVM and CORE at the end.
It's important for Linux linker.

Thank you for the reply. I've tried - unfortunately it doesn't help.

Yes, it works with both dynamic and static linking through using g++ command.

Now what could it be with cmake? I would be grateful for your help. Because g++ command is ok for test application, but not for the whole project))

The answer appeared to be quite simple: cmake somehow links a static version of ipps and dynamic versions of other libs. As I understand, IPP needs to be whole static or whole dynamic. To do so I added

set(IPP_STATIC "ON")

to CMakeLists.txt

I see those names in several of the of the other ipp libs ... try adding more until the references are resolved.  e.g., try adding

find_library(IPP_I libippi.a PATHS /opt/intel/ipp/lib/intel64)
...

target_link_libraries(Test ${IPP_CORE} ${IPP_VM} ${IPP_S} ${IPP_I})

Also, I don't know if order matters (it matters to the linker), but it seems that the most

general library should be at the end :

target_link_libraries(Test  ${IPP_S} ${IPP_I}${IPP_VM}  ${IPP_CORE})
