|
# SYNOPSIS
|
|
#
|
|
# AX_OPENMP([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# This macro tries to find out how to compile programs that use
|
|
# OpenMP a standard API and set of compiler directives for parallel
|
|
# programming (see http://www-unix.mcs/)
|
|
#
|
|
# On success, it sets the
|
|
# OPENMP_CFLAGS/OPENMP_CXXFLAGS/OPENMP_F77FLAGS output variable to
|
|
# the flag (e.g. -omp) used both to compile *and* link OpenMP
|
|
# programs in the current language.
|
|
#
|
|
# NOTE: You are assumed to not only compile your program with these
|
|
# flags, but also link it with them as well.
|
|
#
|
|
# If you want to compile everything with OpenMP, you should set:
|
|
#
|
|
# CFLAGS="$CFLAGS $OPENMP_CFLAGS"
|
|
# #OR# CXXFLAGS="$CXXFLAGS $OPENMP_CXXFLAGS"
|
|
# #OR# FFLAGS="$FFLAGS $OPENMP_FFLAGS"
|
|
#
|
|
# (depending on the selected language).
|
|
#
|
|
# The user can override the default choice by setting the
|
|
# corresponding environment variable (e.g. OPENMP_CFLAGS).
|
|
#
|
|
# ACTION-IF-FOUND is a list of shell commands to run if an OpenMP
|
|
# flag is found, and ACTION-IF-NOT-FOUND is a list of commands to run
|
|
# it if it is not found. If ACTION-IF-FOUND is not specified, the
|
|
# default action will define HAVE_OPENMP.
