fpp
fpp or FPP may refer to one of many Fortran preprocessors:
-
GFortran invokes cpp, the C preprocessor, running in “traditional mode.” (See Enable and customize preprocessing in the GFortran manual). It’s main limitation is the lack of support for variadic macros.
-
The Intel Fortran compiler ships with the Intel Fortran preprocessor, called fpp. (See Can I Invoke fpp from the command line? in the Intel Fortran knowledge base.)
-
The Nvidia compiler (previously PGI) also comes with a preprocessor. (See Command-Line Options in the reference manual.)
-
The NAG Fortran compiler provides a Fortran preprocessor. (See fpp: Fortran preprocessor at NAG.)
-
A preprocessor written in FORTRAN 77 referred to in the paper fpp - A Fortran pre-processor by Adam Boyarski at the Stanford Linear Accelerator Center. This program was originally at
ftp://heplib.slac.stanford.edu/pub/fpp.tar.Zbut is no longer available. -
A Fortran preprocessor written by Sun and made available on Netlib at http://www.netlib.org/fortran/. A thread on comp.lang.fortran describes the modified version by Martin Wilck which uses autoconf.
-
Nelson Beebe’s fpp, inspired by the C-preprocessor. Preprocessing directives are written as Fortran comments. All directives of cpp are supported, with the exception of #include.
