Function ippSetCpuFeatures not loaded with IPP 2021.11

[Showvick]

It appears that function ippSetCpuFeatures isn't loaded when we build zlib 1.2.13 with Intel SDK 2021.11.

sdt34788: # nm -Ca libipp_z.so.1.2.13 | grep -i cpu

sdt34788: #

However, in past, when we build zlib with Intel SDK 2020.4 it has it loaded.

 # nm -Ca libipp_z.so.1.2.11 | grep -i cpu

0000000000000000 a owncpudefs.c

0000000000000000 a owncpufeatures.c

For our product we require the function to disable AVX512 instructions on certain CPUs.

We are building the product in the exact same way. I have attached logs of the old build and the new build.

How can we get these functions to load with 2021.11?

I see no problem with this patch and latest version of IPP 2021.11:

Thanks for that. That worked for me. It needed a minor tweak.

[Gennady_F_Intel]

ok, thanks for confirmation. This thread is closing.
