<p>On the Intel webpage at [1], there is:</p>
<p><i>In late calendar year 2025, all downloads of ifort will be
removed from our repositories and Intel® Registration Center
downloads.</i></p>
<p>I don't see an exact date given, but that "Error 403 Forbidden"
might be an indication that the above has taken place.</p>
<p>On the Intel webpage at [2] under "What kind of support can I
expect for legacy products like Intel<span><em>®</em></span> Parallel
Studio or products that are no longer available to download", it
looks the following is still a way to obtain ifort:</p>
<p><i>Users who originally purchased prior generational products
(like Intel® Parallel Studio XE or Intel® System Studio) and
still have an active Priority Support entitlement may request
access to older downloads and limited installation support by
opening a support ticket [<a class="moz-txt-link-freetext" href="https://supporttickets.intel.com/">https://supporttickets.intel.com/</a>].</i></p>

<p>Thanks Laurence for your suggestions!</p>

<p>1) Using ifort / icc .. Compiling fftw3 with icx of the

<p>2) Unfortunately I have only the latest and last ifort

all,<br>
<br>
<br>
I am back now to ifort 2021.13 because it crashes
much less as the new <br>
ifx compiler, also it produces omp errors using
fftw3 during compilation.<br>
<br>
All worked fine since the last Open Suse Tumbleweed
version using Kernel <br>
6.16.3-1 (Opensuse Tumbleweed 202250827). Parallel
Jobs terminate when <br>
using "mpirun" with the following error. The same
error appears when I <br>
have compiled fftw 3.10 with gcc 15.1 and run "make
check" the check <br>
routine crashes when using mpirun with the same
error.<br>
<br>
<br>
Does somebody know what that relink error means and
how to solve it? Is <br>
it maybe the opensuse libm.so.6 library (glibc
version 2.42.1) causing <br>
the error, because the new version does not contain
the symbol, libmpi <br>
is reqeusting?<br>
<br>
<br>
<br>
Best regards,<br>
<br>
