8.15 Fortran 9x Support

Automake includes support for Fortran 9x.

Any package including Fortran 9x code must define the output variable FC in ‘configure.ac’; the simplest way to do this is to use the AC_PROG_FC macro (see Particular Program Checks in The Autoconf Manual).

A few additional variables are defined when a Fortran 9x source file is seen:

FC

The name of the Fortran 9x compiler.

FCFLAGS

Any flags to pass to the Fortran 9x compiler.

AM_FCFLAGS

The maintainer’s variant of FCFLAGS.

FCCOMPILE

The command used to actually compile a Fortran 9x source file. The file name is appended to form the complete command line.

FCLINK

The command used to actually link a pure Fortran 9x program or shared library.
