# SYNOPSIS |
|
# |
|
# AX_BOOST_SYSTEM |
|
# |
|
# DESCRIPTION |
|
# |
|
# Test for System 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_SYSTEM_LIB) |
|
# |
|
# And sets: |
|
# |
|
# HAVE_BOOST_SYSTEM |
