Downloaded the Linux online installer from:
https://www.intel.com/content/www/us/en/developer/tools/oneapi/fortran-compiler-download.html?operatingsystem=linux&distribution-linux=online
Then executed:
$ ./intel-fortran-compiler-2025.0.4.21.sh
Then did:
$ source ~/intel/oneapi/setvars.sh
Then, as per instructions, entered into hello.f90:

print *, "Hello, world!"
end
$ ifx -o hello hello.f90
ld: cannot find -lm: No such file or directory
ld: cannot find -lpthread: No such file or directory
ld: cannot find -lc: No such file or directory

Bummer...

Then did:
sudo apt install gfortran

Miraculously, hello.f90 then compiled. :)
