.Sh DESCRIPTION
|
|
.Nm f77
|
|
is a simple driver for the FORTRAN compilation process under FreeBSD.
|
|
.Pp
|
|
.Nm f77
|
|
calls the FORTRAN to C translator
|
|
.Nm f2c
|
|
to translate the FORTRAN source to C. Then it calls
|
|
.Nm cc
|
|
to compile the resulting C code and
|
|
.Nm as
|
|
to assemble it. After this stage it may call
|
|
.Nm ld
|
|
to link the resulting object files together with the
|
|
.Nm f2c
|
|
library
|
|
.Nm libf2c
|
|
, the
|
|
.Nm math
|
|
library
|
|
.Nm libm
|
|
and other user specified libraries into an executable. Files ending in other
|
|
suffixes than .f (.o, .c, ...) are also accepted in the commandline and will
|
|
processed by the appropriate program.
|
|
.Pp
|
|
From the user side of view this FORTRAN to C translation is completely
|
|
transparent -
|
|
.Nm f77
|
|
looks like a traditional FORTRAN compiler.

|

|
|
Available options:
|
|
.Pp
|
|
The options that
|
|
.Nm f77
|
|
recognizes are a superset of the
|
|
.Nm f2c
|
|
and the
|
|
.Nm cc
|
|
options - please refer to their manpages for more details.

The input file must end in .f - for instance .for will give problems.
