6# mpif77
7# Simple script to compile and/or link MPI programs.
8# This script knows the default flags and libraries, and can handle
9# alternative C compilers and the associated flags and libraries.
10# The important terms are:
11#    includedir, libdir - Directories containing an *installed* mpich2
12#    prefix, execprefix - Often used to define includedir and libdir
13#    FC                 - Fortran 77 compiler
14#    WRAPPER_FFLAGS        - Any special flags needed to compile
15#    WRAPPER_LDFLAGS       - Any special flags needed to link
16#    MPILIBNAME         - Name of the MPI library
17#    MPI_OTHERLIBS      - Other libraries needed in order to link
18#    F77_OTHER_LIBS     - Yet more libraries, needed just with F77
19#   
20#   
21# We assume that (a) the C compiler can both compile and link programs
22#
23# Handling of command-line options:
24#   This is a little tricky because some options may contain blanks.
25#
26# Special issues with shared libraries - todo

67# where F77name is the name of the compiler with all spaces replaced by hyphens
68# (e.g., "f77 -64" becomes "f77--64", that file is sources, allowing other
69# changes to the compilation environment.  See the variables used by the

85# This is somewhat awkward because of the handling of arguments within
86# the shell.  We want to handle arguments that include spaces without
87# loosing the spacing (an alternative would be to use a more powerful
88# scripting language that would allow us to retain the array of values,
89# which the basic (rather than enhanced) Bourne shell does not.
