I installed parallel_studio_xe_2018_update4_composer_edition_for_cpp in Suse Leap 15. I chose the 30-day trial license, as I was not sure that it will work in the newer distro (it is not listed as a supported OS). Then I installed parallel_studio_xe_2018_update4_composer_edition_for_fortran.
It did not ask about what type of license I will use. I can run icc or icpc, but ifort reports:
Error: A license for (Comp-FL) could not be found.
Indeed Comp-FL is not in the license file.
I am sure I did this years ago, with 2012 or 2013 version of Intel compilers (which seemed to have different license files) and I could run ifort as well.
So how should the fortran compiler be installed? Or is it not possible to get 30-day license for both compilers?
Did you activate the license, download and install the license file? I believe that if the downloaded files are separate packages for C++ and Fortran they also necessitate different license files. I actually didn't know that it is still possible to download separate packages, and not a unified one for C, C++, and Fortran.
You need separate licenses for those two products. I'm a bit surprised, though, as I thought that Intel provided only the Cluster Edition (which includes all the tools) for evaluation. Maybe this changed in the past two years.
Intel does still sell C-only and Fortran-only versions of the Composer Edition (as well as one with both). There are many customers who use only one of the languages. The higher editions all contain both compilers.
Okay, so I found version 2019 now has update 1, and downloaded the cluster edition (5 billion bytes!) as it supports SLE 15.
Just did the evaluation license, as RHEL 8 beta is now out. Once I have installed that, I will want to see if the compilers work
on that, or I will have to wait for Intel 2020?
You probably won't have to wait that long. Intel often supports newly released distros in updates. But Intel tends not to support OS betas.
