$ ifx –o hello hello.f90 => Looks like the issue here is a typo in
Intel's documentation where you copied and pasted from it an en dash (–)
instead of a dash (-).
ifx: error #10236: File not found: '–o'
make: ifort: No such file or directory => In siteconfig, you probably
specified "Your compiler: ifort".
If using ifx, you need to specify:
***********************************************************************
* Specify compilers *
***********************************************************************
Recommended setting for f90 compiler: ifort
Current selection (for current default just press ENTER): ifx
Your compiler: ifx
There is a "WIEN2k24.1_Ubuntu22.04_Install_with_OneAPI(ifx).pdf" file
that might help you compile with ifx using -O0:
https://github.com/gsabo/WIEN2k-Docs
The recent discussions have been about compiling ifx with higher
optimization (-O):
https://www.mail-archive.com/[email protected]/msg23567.html
If you want to compile with gfortran instead, there is also a
"WIEN2k24.1_Ubuntu24.04.1_Install_with_gfortran.pdf" file at:
https://github.com/gsabo/WIEN2k-Docs
To follow the steps in those PDF, you might have to remove the WIEN2k
install folder and start over with the tar file. Alternatively, you
could try removing the WIEN2k_INSTALLDATE file before running siteconfig:

The problem with ifort for users that don't have the older OneAPI
installed or if it gets removed in an update is Intel removed the free
public download link in the summer of 2024 to the last OneAPI version
2024.2.0 that contained it. That older version should still be
obtainable by those who bought Intel's Priority Support by logging into
the Intel Registration Center according to the webpage:
https://community.intel.com/t5/Blogs/Tech-Innovation/Tools/A-Historic-Moment-for-The-Intel-Fortran-Compiler-Classic-ifort/post/1614625
There is a thread of Intel posts about the slow program execution times
when compiled with ifort compared to ifx at:
https://community.intel.com/t5/Intel-Fortran-Compiler/Last-build-for-ifort-and-plans-for-removing-ifort-from-packages/m-p/1615558
One of the developers on the Intel software team says in one post they
are working on the performance issues and states about it:
/And as a software developer, you know that not all issues are created
equal: some can be fixed over a cup of coffee, others take months or
years and major refactoring.
/
Hope that helps,

Did you follow the recent discussions about ifort and ifx in the
mailing list ???
Most likely at the moment an unexperienced user CANNOT use the latest
OneAPI versions.
In your siteconfig you still use ifort as compiler name and got
the following message:
make: ifort: No such file or directory
What do you think could be the reason for this message:
It simply means, the program ifort does NOT exist on your computer
(in your path). Why is this ? If you have read the many mails on the
mailing list you should know that ifort does not exist anymore in
recent OneAPI versions and has been replaced by ifx.
However, at the moment it is not clear if IWEN2k can be compiled by
ifx.
I recommend to use gfortran and openblas at the moment.
There were recent posts on the mailing list with detailed instructions
for gfortran+openblas on some Linux systems.

Subject: Re: [Wien] Error in Installation of Wien2k
Dears,
I managed to remove the warning from the terminal, the issue was that
there was a duplicate entry of source /opt/intel/oneapi/setvars.sh in
the .bashrc file.
But hello world program is not running, with below error:
$ ifx –o hello hello.f90
ifx: error #10236: File not found: '–o'
ifx: error #10236: File not found: 'hello'
Moreover, also facing the warning and errors at the end while doing
compilation of Wien2k via ./siteconfig_lapw :
ifort -c -O -FR -mp1 -w -prec_div -pc80 -pad -ip -DINTEL_VML
-traceback -assume buffered_io -I/opt/intel/oneapi/mkl/2025.0/include
blas_lapw1.f
make: ifort: No such file or directory
