# F2PY and PGI Fortran on Windows

A variant of these are part of the so called “classic” Flang, however, as classic Flang requires a custom LLVM and compilation from sources.

Warning

Since the proprietary compilers are no longer available for usage they are not recommended and will not be ported to the new `f2py` CLI.

Note

As of November 2021

As of 29-01-2022, PGI compiler toolchains have been superseded by the Nvidia HPC SDK, with no native Windows support.
