| 5 | # SYNOPSIS | |
| 6 | # | |
| 7 | # AX_BOOST_SIGNALS | |
| 8 | # | |
| 9 | # DESCRIPTION | |
| 10 | # | |
| 11 | # Test for Signals library from the Boost C++ libraries. The macro | |
| 12 | # requires a preceding call to AX_BOOST_BASE. Further documentation is | |
| 13 | # available at <http://randspringer.de/boost/index.html>. | |
| 14 | # | |
| 15 | # This macro calls: | |
| 16 | # | |
| 17 | # AC_SUBST(BOOST_SIGNALS_LIB) | |
| 18 | # | |
| 19 | # And sets: | |
| 20 | # | |
| 21 | # HAVE_BOOST_SIGNALS | |
| 22 | # | |
