# Simple script to compile and/or link MPI programs.
|
|
# This script knows the default flags and libraries, and can handle
|
|
# alternative C compilers and the associated flags and libraries.
|
|
# The important terms are:
|
|
# includedir, libdir - Directories containing an *installed* mpich
|
|
# prefix, execprefix - Often used to define includedir and libdir
|
|
# CC - C compiler
|
|
# WRAPPER_CFLAGS - Any special flags needed to compile
|
|
# WRAPPER_LDFLAGS - Any special flags needed to link
|
|
# WRAPPER_LIBS - Any special libraries needed in order to link
|
|
#
|
|
# We assume that (a) the C compiler can both compile and link programs
|
|
#
|
|
# Handling of command-line options:
|
|
# This is a little tricky because some options may contain blanks.
|
|
#
|
|
# Special issues with shared libraries - todo
