Intel Fortran unknown option

[WexeI]

Its working with gfortran but not with ifort. How can I change unknown option?

$ fpm build --compiler ifort --flag ' /warn:all /Qopenmp'
common_mod.f90                         done.
.............
main.f90                             done.
main.exe                             failed.

There should be the corresponding --link-flags / --ar-flags options to overwrite arguments passed to the linker / archiver.

I've not been able to reproduce this issue; can you tell us a little more about your environment? Are you running this from the Windows command prompt or via some another shell? Are you able to show us the output with the --verbose flag added? Thanks.

From my experience of using the Windows-ifort environment, you probably haven't fully established the ifort environment.
As far as I know, the oneAPI environment has a lot of components that need to be introduced into the environment variables. It is not enough to just introduce ifort into the environment path, preferably using the Intel oneAPI command prompt for Intel 64 for Visual Studio 2022 in the Windows start menu to start the oneAPI environment.

## The following is the command used in Powershell
## - Introduce only ifort to PATH ❎
>> $Env:PATH += ";C:\Program Files (x86)\Intel\oneAPI\compiler\2022.1.0\windows\bin\intel64\"
>> fpm run --compiler ifort
main.f90                               done.
