Fortran Interface

The Fortran interface is provided through the fmsg_m module. This module defines the specgrid_t, photgrid_t and axis_t derived types, together with supporting parameters and procedures.

Compiling/Linking

The module file fmsg_m for the Fortran interface is provided in the directory $MSG_DIR/include, and executables should be linked against $MSG_DIR/lib/libfmsg.so (Linux) or $MSG_DIR/lib/libfmsg.dylib (MacOS). To simplify this process, a script $MSG_DIR/scripts/fmsg_link is provided that writes the appropriate linker commands to standard output. This script can be used to compile/link a program with gfortran as follows:

gfortran -I $MSG_DIR/include -o myprogram myprogram.f90 `$MSG_DIR/scripts/fmsg_link`
