ax_boost_wave

Synopsis

AX_BOOST_WAVE

Description

Test for Wave 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_WAVE_LIB)

And sets:

  HAVE_BOOST_WAVE
