ldconfig: /opt/intel/oneapi/redist/lib/libmkl_sycl.so is not an ELF file

Running AlmaLinux 8.9 with intel-oneapi-runtime-mkl-2024-2024.0.0-49656.x86_64

When running yum/dnf updates I get the following output:

Running transaction

Hi,

Thanks for posting in Intel Communities.

>>Running AlmaLinux 8.9 with intel-oneapi-runtime-mkl-2024-2024.0.0-49656.x86_64

From the information provided by you, we can see that you are using Alma Linux which is not a supported Operating System as per the  Intel MKL System Requirements. We recommend you use the supported Operating System.

Also, if your issue persists with the supported Operating Systems, could you please provide us with the details of the OS and the steps you have followed to reproduce the issue at our end?

Thanks & Regards,

Varsha

AlmaLinux is a RedHat Enterprise Linux clone like CentOS and Rocky Linux, so it should be equivalent.

Hower I can reproduce it on RHEL8.9 with:

root@vmrhel8.cora.nwra.com [~]# yum install intel-oneapi-runtime-mkl-2024-2024.0.0-49656.x86_64 -y

I am having the same problem, installing on SLES12 SP5.  Would you please provide a working libmkl_sycl.so[.3] file?

Note that libmkl_sycl.so is 144 characters.  Its file type:

libmkl_sycl.so: ASCII text

Thanks,

Martha

[Gennady_F_Intel]

the problem would be fixed the next update of oneMKL. We will keep this thread updated.

as a temporarily workaround you could just remove libmkl_sycl.so 

[lzyla]

same issue here on ubuntu 23.10

[jdal]

This is also happening with ubuntu 22.04.3. The file has a length of 144 and doesn't appear to have been properly compiled.

[Gennady_F_Intel]

as we noticed above, the problem will be fixed in the next update ( 2024.1) of oneMKL. 

check the MKL Linker Adviser to see how properly links against oneMKL.

[cpmech]

The issue persists in 2024.2

[crobar]

Issue persists in 2025.0

at least when installing from apt on Ubuntu

[JW___mkl]

Same issue on 2025.0 on RHEL/Fedora

Looks like an issue with your build scripts.

[Viraj_M_Intel]

Starting 2024.0, mkl_sycl library is split into domain-specific libraries. This is particularly helpful when redistributing oneMKL with only specific domain functionality.

libmkl_sycl.so is not an ELF file but it is a linker script which links the application with all oneMKL supported domains using the INPUT command:

INPUT(-lmkl_sycl_blas -lmkl_sycl_lapack -lmkl_sycl_sparse -lmkl_sycl_dft -lmkl_sycl_vm -lmkl_sycl_rng -lmkl_sycl_stats -lmkl_sycl_data_fitting)

Hence, the ASCII file type is expected.

Your installation will contain the files listed above within the INPUT command.

More on linker scripts and commands: Using LD, the GNU linker - Command Language

Is there a problem other than the file type that affects linking with oneMKL or with ldconfig usage after 2024.1 release?

[JW___mkl]

Thanks @Viraj_M_Intel this makes sense

[Orion_P_]

I'll just note that with intel-oneapi-runtime-mkl-2025.1.0-801.x86_64 this file is no longer present.

[Shiquan_Su]

In my oneapi 2025.1 installation, I can find libmkl_sycl.so here:

[Orion_P_]

Sure, but that's not a path in /etc/ld.so.conf.d/intel-oneapi-runtime.conf and so ldconfig no longer complains about it.
