Warnings while building MKL 2024.0 with gcc 8.3

[Aniket_Mane]

Hi, 
I'm trying to upgrade MKL version in our application to 2024.0

I'm not getting any warnings while building application with GNU 4.8.5, however I get below warnings on GNU 8.3 version.

How do I fix these?

/opt/rh/devtoolset-8/root/usr/libexec/gcc/x86_64-redhat-linux/8/ld: warning: <mkl lib path>/mkl_linux/2024.0/lib/intel64_lin/libmkl_core.a(_mc3_dtrmm_ll.o): unsupported GNU_PROPERTY_TYPE (5) type: 0xc0010001

could you show how did you link against onemkl?

Thanks for your response.

I'm adding below for linking:

-Wl,--start-group {mkl path}/mkl_linux/2024.0/lib/intel64_lin/libmkl_intel_lp64.a {mkl path}/mkl_linux/2024.0/lib/intel64_lin/libmkl_intel_thread.a {mkl path}/mkl_linux/2024.0/lib/intel64_lin/libmkl_core.a -Wl,--end-group -liomp5 -lpthread -lm -lresolv -lrt -lintexcmo -ldl

Aniket,

We see the problem on our end either

and will try to investigate the cause of this case.... meantime, we could see

the very similar reports e.x. here (https://github.com/intel/linux-sgx/issues/785

) and the cause of the problem is related to version of binutils used.

into this thread, I see as follows: "After following the instructions here to install the toolchain mitigations,

these warnings no longer appear on linking."

I hope it will help you as well.
