| 5 | +# SYNOPSIS |
| 6 | +# |
| 7 | +# AX_BOOST_THREAD |
| 8 | +# |
| 9 | +# DESCRIPTION |
| 10 | +# |
| 11 | +# Test for Thread library from the Boost C++ libraries. The macro requires |
| 12 | +# a preceding call to AX_BOOST_BASE. Further documentation is available at |
| 13 | +# <http://randspringer.de/boost/index.html>. |
| 14 | +# |
| 15 | +# This macro calls: |
| 16 | +# |
| 17 | +# AC_SUBST(BOOST_THREAD_LIB) |
| 18 | +# |
| 19 | +# And sets: |
| 20 | +# |
| 21 | +# HAVE_BOOST_THREAD |
