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?
