failure of fortran oneAPI base+HPC to function


@Ron_Green  The attached 2pp file gives the history of my inability to get the referenced compiler to do its job, and an earnest plea for assistance.

@Ward_B_Watt I had to remove your doc file as it had your license key.  We don't advise that as anyone could have attempted to steal it for their own use.  I saved my own copy, however.


It looks like an environment issue.  Once you have that window open, and you have run the vars batch file, do this command and capture the full output:

echo %PATH%


I will have more suggestions but first I need to charge my PC laptop.

It appears you have both oneapi Base Toolkit and HPC Toolkit installed.  And yes, the "access denied" during the run of the batch script is a strong indicator of a problem.  Looks like maybe an error in the python kit.


So let's simplify


Uninstall all of Base Tookit and HPC Toolkit, HPC first, Base second.  Use Settings -> Apps -> Intel oneAPI * Toolkit -> uninstall

remove both.


This should leave you with VS2019 with just Microsoft C/C++ installed (you did install the C++ Component in VS 2019?)

Then just to be safe, reboot.


Next, read my article on installing JUST the Compilers:


and download and install JUST Fortran compilers.  Just this 1 package, no more at this time.


Now, open the special

'Intel oneAPI command prompt for Intel 64"

and NOT a Windows command prompt!

Do this from desktop:

Start -> Intel oneAPI 2022 -> Intel oneAPI command prompt for Intel 64 for Visual Studio 2019


in this window, try

ifort /V 

does that give the Ifort logo information and an error that no files specified?

Thanks for your advice.  I do still get the error message that no file is specified. 

Here is the output from the echo %PATH% command,

I have not counted the path lenght you have, but if it is over 260 characters, you may have problems. 


i just counted it it is 3260 characters.  I would start there. 


Just a thought

can you find or create a 'helloworld.f90' program

compile with 

ifort  helloworld.f90


and attach the output.

next, same for this command


ifort -# helloworld.f90

I am a molecular evolutionary geneticist (now “emeritus”, but still active) support period end 2023-09-29, license number etc. available to those authorized) for the Intel oneAPI base + HPC combined toolkit. It did not work. Being overworked myself, I could spare only limited time to struggle with it until recently, despite some kind suggestions from Ron Green centered on functional conflict between certain oneAPI Fortran releases and Microsoft Visual Studio, MVS being the source of the conflict.


My fundamental interest here is in being able to use the oneAPI compiler to program biological models, not to develop code features to begin with.  Accordingly, can you advise me which versions of oneAPI Fortran are functionally compatible with what is now hopefully a corrected version of MVS? If you can supply me with that advice on functional compatibility of the software in question, my problem will be solved.

The current version of the oneAPI HPC Toolkit (2023.1) works with the current version of Visual Studio 2022 or 2019.
