Hello,
I am using the Fortran oneAPI Fortran Compiler Classic 2021.1.1 with Visual Studio 2019.
I am trying to call a function in a Fortran static library I have built, from a C++ program.
I combine both projects in a single Visual Studio solution, define the dependencies for the C++ project (= it depends on the Fortran object file).
The fortran library builds first without any problem, the C++ source compiles, but then the linker gives me the following error:
LINK : fatal error LNK1104: cannot open file 'ifmodintr.lib'
From my understanding, I need to follow the solution of the following link:
However, this link is out-of-date, as it apparently does not cover Visual Studio 2019 and the oneAPI compilers. I wanted to ask if it is possible for Intel to update the instructions, or if someone can explain which of the previous versions' procedure (and with what changes) will work.
Link Copied

Referring to that article, the x64 build library is
IFORT_COMPILER21, which should evaluate to
C:\Program Files (x86)\Intel\oneAPI\compiler\2021.1.1\windows\
Look up the IFORT_COMPILERxx env var, like IFORT_COMPILER21. TO see you env vars, web search "How do I view environment variables in Windows 11?" or WIndows 10.
Should be that IFORT_COMPILER21, or IFORT_COMPILER22, or IFORT_COMPILER19. Again, check your Settings, Advanced, Environment Variables to confirm. I don't have your compiler version on my PC. It should be something like
c:\Program Files (x86)\Intel\oneAPI\compiler\2021.1.1\compiler\windows
Include:
you can use $(IFORT_COMPILER21)\compiler\include:$(Include_Path)
Lib dir
$(IFORT_COMPILER21)\compiler\lib\intel64:$(LibraryPath)
this assumes you are using the Intel64 build for the C++ project.
I'll see if one of my Windows saavy colleagues can update that web page you referenced
