FORTRAN for Win32

[BroSte]

What is the last version of OneAPI which must be used to generate x86 Fortran code?

I installed the version 2025.3 and it seems to only consider 64 bits compiler.

Intel dropped support for 32 bit in 2023 with the move to replace ifort with the ifx compiler. You might be able to get hold of an earlier download that includes 32 bit if you pay for support.

From oneAPI 2024 onward, Intel dropped the IA-32 (x86 32-bit) Fortran compiler support only x86-64 is available now. The last releases that still included 32-bit Fortran were in the oneAPI 2023 line on Windows. If you specifically need Win32 output, you’ll have to stick with oneAPI 2023 classic Intel Fortran (ifort) or an older standalone Intel Parallel Studio build, 2025.3 won’t do it.

In fact, the latest version of the Intel oneAPI toolkit to include the ifort compiler is 2024.2.0 (ifort 2021.13.0):
