Hi,

Using cmake 3.22.2 or later and ninja 1.11.0 with Intel oneAPI 2022.1 we get with the following CMakeList.txt:

cmake\_minimum\_required(VERSION 3.22.2)

set ( CMAKE\_C\_COMPILER “C:/Program Files (x86)/Intel/oneAPI/compiler/2022.1.0/windows/bin/icx.exe” )  
set ( CMAKE\_CXX\_COMPILER “C:/Program Files (x86)/Intel/oneAPI/compiler/2022.1.0/windows/bin/icx.exe” )  
set ( CMAKE\_Fortran\_COMPILER “C:/Program Files (x86)/Intel/oneAPI/compiler/2022.1.0/windows/bin/ifx.exe” )

# set the project name

project(Tutorial C CXX Fortran)

The following output on Windows:

– The C compiler identification is IntelLLVM 2022.1.0 with MSVC-like command-line  
– The CXX compiler identification is IntelLLVM 2022.1.0 with MSVC-like command-line  
– The Fortran compiler identification is unknown

CMakeFortranCompilerId.F: fatal: can’t fopen file: C:/Users/f.i

It seems that the intel ifx has the problem when one tries to compile by  
ifx -fpp source.f  
then output is  
source.F: fatal: can’t fopen file: C:/Users/f.i  
I’ll post that in the intel forum…

Please close this thread because it has nothing to do with cmake.  
Its the problem of intel ifx when TMP variable points to path with dots e.g. /c/f.roeser/tmp.  
There is an entry in the intel forum.
