Intel OneAPI Fortran Compiler ifx works with MSVS 2019 (16.11.55) for old source files

WH- — Mon, 11 May 2026 04:02:18 GMT

Hello folks,

I've got a couple of questions as follows:

Q1. Does Intel Fortran Compiler ifx.exe work with MSVS- Microsoft Visual Studio 2019 (16.11.55) ?

I've tried to switch modes between Console and Windows in order for a test-run of the project named "Hello World" on the system of "Windows 11 Home." Unfortunately, it kept turning out the message indicating: "The code execution cannot proceed because libifcoremdd.dll was not found. Reinstalling the program may fix this problem." However, this dll file has been sitting with ifx.exe in the same directory "bin" since ifx.exe compiler was installed.

Q2. As what was done in the years of 1990's, I'm wondering if there is still a makefile program like Make.exe to compile/link a group of project files into an executable code to be able to run on the Windows command mode?

The latest ONEAPI has been released. Although the Intel note on this forum said the Fortran compiler is available they did not mention you really need the whole lot as you need DPC upgrade, it is easy to find. It will not update through control panel as there is only one API installer not the LPC and HPC.

It will only install with 2026 and 2022, you need to ditch VS 2019, the latest 2026 and ONEAPI will install in a few minutes and it runs old code nicely.

The minor annoyances are not worth the hassle.

Make is still around. It is much easier to just compile a SLNX VS file and just run in a nice IDE.

Thank Mr. Nichols so much for the big help. After having followed your kind instructions, I finally got Fortran Compiler ifx.exe worked out for my first project, TestRun with only one statement as Print *, 'Hello World' in the source code. It's going to take some time- maybe several days or even weeks on learning SLNX VS files and then just run in a nice IDE. Thanks again.

Got any clues for share? I'm still suffering.

Dear John,

Thanks a lot for your kind support two weeks ago, I have followed your helpful information for VS and Intel OneAPI upgrade and even further got to the bottom of my old Fortran code. My old Fortran source codes were then put in one file, named Cosole1.f90 for project 1 and all the way up to console3.f90 for project 3 within the VS2026 platform. After 2-3 tries per project to "Build and/or Rebuild" all three console projects (IFX), they all ended up with similar message as follows:

Console3 - 0 error(s), 0 warning(s)
========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========
========== Rebuild completed at 12:58 PM and took 00.202 seconds ==========

In fact, minor warning or error messages were only generated a couple of times. Once the errors get corrected, IFX.exe kept doing nothing except for the messages shown above. The three projects contain the same Fortran code with the lower heading part of messages in the following; will ifx remember the program name CRVGRD and stop compiling work immediately?

Console3.f90

ZIP it all into a zip file and upload your solution folder, I am lost in your descriptions.

Hi John:

Having attached the Zip file ready for you, I really have no idea what's going on along with the installation.

Thanks in advance for taking into the problem.

Best Regards,

Wen

You code is designed for .for file and it is a f90 file

I have fixed fist 1000 lines, I cannot do 4000 lines.

It compiles on absolute latest VS and Oneapi, with errors

You need to stop speaking 1993 Fortran and update to at least 2008.

Example

common /BR!/ is an error the ! is in the wrong place.

But you have enough samples now

Hello John,

Thank you so much for editing my old code into a thousand lines to make a good example for me to follow.

I really appreciate your kindness very much.

Since your attachment has nothing to download, would you please upload your work examples so that I can see the first 1,000 lines and finish the rest 3,000 lines more?

Thanks again for looking deep into the problem.

Best Regards,

Wen

I just did a simple syntax correction for the example of the exclamation! in the wrong place

by substiputing block "common /BR!C/" with "common /BR!C/". Then, I resubmit Rebuild Console3 (IFX) in VS2026.

Here follows Part Console3.f90 and the compiler still said the same thing, so other than lots of obsolete language used in the source code, both the installation of compiler and skip of registration might all have to be fixed...
