# SYNOPSIS
|
|
#
|
|
# AX_BOOST_PROCESS
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Test for Process library from the Boost C++ libraries. The macro
|
|
# requires a preceding call to AX_BOOST_BASE. Further documentation is
|
|
# available at <http://randspringer.de/boost/index.html>.
|
|
#
|
|
# This macro calls:
|
|
#
|
|
# AC_SUBST(BOOST_PROCESS_LIB)
|
|
#
|
|
# And sets:
|
|
#
|
|
# HAVE_BOOST_PROCESS
