dnl @synopsis AX_BOOST_DATE_TIME

dnl
|
|
dnl This macro checks to see if the Boost.DateTime library is
|
|
dnl installed. It also attempts to guess the currect library name using
|
|
dnl several attempts. It tries to build the library name using a user
|
|
dnl supplied name or suffix and then just the raw library.
|
|
dnl
|
|
dnl If the library is found, HAVE_BOOST_DATE_TIME is defined and
|
|
dnl BOOST_DATE_TIME_LIB is set to the name of the library.
|
|
dnl
|
|
dnl This macro calls AC_SUBST(BOOST_DATE_TIME_LIB).
