# SYNOPSIS
|
|
#
|
|
# AX_BOOST_ASIO
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Test for Asio 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_ASIO_LIB)
|
|
#
|
|
# And sets:
|
|
#
|
|
# HAVE_BOOST_ASIO
