Compiling and linking

Fortran M version

This section describes how to compile and link a program based on the Fortran M implementation. It assumes that the Fortran M compiler (fm) [2, 1] is installed.

To compile and link a program based on the Fortran M implementation:

• Compile the ``main program file'' -- the file containing the archetype-supplied program skeleton plus the user-supplied code for the programs that execute in the host and grid processes.
• Compile any additional source files (e.g., for user-written subroutines called from the host and grid programs).
• Compile the archetype library routines (mesh_lib.FM).
• Link the results of the above compilations.

For example, to compile the skeleton program p0.FM shown earlier:

        fm -c p0.FM
        fm -c mesh_lib.FM
        fm -o p0.exe p0.o mesh_lib.o

Observe that the library routines and the main program file must be recompiled if any of the PARAMETERs in mesh_uparms.h are changed -- this is because of the static nature of Fortran 77, on which Fortran M is based.

Fortran M version with parallel I/O

To include the optional parallel I/O, compile all the provided C routines (.c files) with a C compiler and include the resulting .o files in the above link. See the sample Makefile for an example. The utility programs split and merge must be compiled separately.

Other implementations

Compilation is similar to that for Fortran M, but using the appropriate compiler and/or message-passing library. See the sample Makefile for an example.
