Setting environment variables on Windows

[Petr_Parik]

Hi,

I have installed the newest Intel Fortran Compiler for Windows (oneAPI 2023.2.0), but I can't figure out how to set the environment variables to use ifort from the command line.

In older versions, I just needed to run

"%IFORT_COMPILER12%\bin\compilervars.bat" intel64 

to be able to invoke ifort, but this does not work anymore.

Here is the output of the setvars.bat file:

Microsoft Windows [Version 10.0.19044.3086]

I don't need or want to install Visual Studio.

I'd be grateful for any advice.

Best, Petr

The Intel Fortran Compiler relies on the Visual Studio tools (linker, CRT, etc.) to function. Regardless of whether or not you intend to use the Visual Studio IDE, you will need to install the desktop VC++ development package from Microsoft. That is a prerequisite, and setting environment variables is no substitute.

I have installed standalone VS Build Tools. It seems to work when I first run "x64 Native Tools Command Prompt for VS 2022" and then from within I run Intel oneAPI setvars.bat .

Thank you.

It should not be necessary to run setvars.bat manually - this is done as part of the "native tools command prompt".

Oh, wait. I was thinking of the command prompt that comes under the Intel Fortran menu.

So, the environment is still not set up properly, because ifort complains about missing libraries (ifmodintr & ifconsol). In older versions (compilervars.bat), this was set up by the 'intel64' parameter. It does not seem to work now.

EDIT: Solved, it was my mistake overwriting the LIB environment variable.
