How to download older version of Intel oneAPI HPC Toolkit for Centos 7?ins

[tanglaoya]

Dear administrator,

I need to install Intel oneAPI HPC Toolkit on Centos 7 (I can't change the OS), I tried the latest version and build my program with -mkl, the following errors displayed:

/opt/intel/oneapi/compiler/2025.2/bin/compiler/xfortcom: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by /opt/intel/oneapi/compiler/2025.2/bin/compiler/xfortcom)

/opt/intel/oneapi/compiler/2025.2/bin/compiler/xfortcom: /lib64/libc.so.6: version `GLIBC_2.28' not found (required by /opt/intel/oneapi/compiler/2025.2/bin/compiler/xfortcom)

therefore, I need to install an older version, could you please give me the best version and download link to get this package?

Thanks,

Tang Laoya

At the top of the forum there is a sticky topic on "

"

Thank you very much for your kindly reply.

However, when logged into the download center, the following error message displayed:
An unexpected error occurred. Please refresh and try again or contact Intel support.

Thanks,

Well if that persists raise a ticket if you have support, otherwise and Intel person might pick that up for here in due course.

I think you are going to have to be creative and go looking for the files, if not on your computer then try another installation.  

I found this https://stackoverflow.com/questions/55363823/redhat-centos-glibc-2-18-not-found

You might be out of luck.

Thank you very much for your kindly reply. 

However, after installed Redis 3.2 and launched the service, the same build errors still displayed.

Which steps did I miss?

Thanks,

Centos and Redhat 7 support was dropped with the 2023 versions.  You'd need a 2022 version and that is no longer available for download.

CHeck to see where ifx is finding libc.so.  use the commands
which ifx

ldd <path>/ifx

Below is an example.  'ldd' will show you where the compiler is finding libc.so

$ which ifx
/nfs/pdx/disks/cts2/tools/oneapi/2025.2.0/compiler/2025.2/bin/ifx
$ 
$ ldd /nfs/pdx/disks/cts2/tools/oneapi/2025.2.0/compiler/2025.2/bin/ifx
	linux-vdso.so.1 (0x000076242d7e6000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x000076242d6eb000)
	libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x000076242d6bd000)
	libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x000076242d6b8000)
	libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x000076242d6b1000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x000076242d400000)
	/lib64/ld-linux-x86-64.so.2 (0x000076242d7e8000)

Thank you very much for your kindly reply. The 'ldd' shows the following information:

$ldd /opt/intel/oneapi/compiler/2025.2/bin/ifx
	linux-vdso.so.1 =>  (0x00007ffd1d1f4000)
	libm.so.6 => /lib64/libm.so.6 (0x00007efce37c4000)
	libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007efce35ae000)
	libdl.so.2 => /lib64/libdl.so.2 (0x00007efce33aa000)
	libpthread.so.0 => /lib64/libpthread.so.0 (0x00007efce318e000)
	libc.so.6 => /lib64/libc.so.6 (0x00007efce2dc0000)
	/lib64/ld-linux-x86-64.so.2 (0x00007efce3ac6000)

what is next step?

Thanks,

The Intel Registration Center (IRC) has SOME older HPC Toolkits for download.  However, the oldest version available for Download via IRC is 2023.  If you have paid Priority Support you can open a ticket on the Online Service Center and ask if someone can send you this older version of the HPC Toolkit. 

I do see some v2022 COMPILER packages available on IRC.  but these will not have Intel MPI, MKL, or any other oneAPI tool.  And you will need a valid support contract on Intel Priority Support to have access to these older compiler versions.
