fc1

Usage

Overview

fc is a script intended to be used as a front end to the f2c FORTRAN-to-C translator. It is supposed to make the whole f2c and C compiler setup look like a real Fortran compiler.

File arguments with a .f suffix are compiled as Fortran source. Files with a .F suffix are passed through the C preprocessor cpp(1) first. Files with .c (C source) or .s (assembly source) suffixes are passed to the C compiler directly. Files with a .e suffix are treated as efl source files, and files with a .r suffix are treated as RATFOR source files.

Options

-o objfile

Produce an output executable named objfile rather than using the default name a.out.

-c

Do not call the linker; instead, leave relocatable object files as *.o.

-S

Produce assembly output as file.s

-C

Compile in extra code to check that array subscripts are in bounds.

-l library

Libraries specified with this option are passed to the linker.

-U def

Definitions specified with this option are passed to C compiler (for .c files) or to cpp (for .F files) to remove definition.

-u

Complain about undeclared variables.

-v, --version

Print version of f2c in use

-w

Omit all warning messages.

-w66

Omit Fortran 66 (Fortran IV) compatibility warning messages.

-D switch

The given switch is passed to the C compiler (for .c files), to cpp (for .F files) and to f2c.

-I includepath

Passed to the C compiler (for .c files), to cpp (for .F files) and to f2c.

-Ntnnn

Allow nnn entries in table t.

-P

Emit .P files.
