Automake includes full 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.
